Conveying Modified Versions. + + If you modify a copy of the Library, and, in your modifications, a +facility refers to a function or data to be supplied by an Application +that uses the facility (other than as an argument passed when the +facility is invoked), then you may convey a copy of the modified +version: + + a) under this License, provided that you make a good faith effort to + ensure that, in the event an Application does not supply the + function or data, the facility still operates, and performs + whatever part of its purpose remains meaningful, or + + b) under the GNU GPL, with none of the additional permissions of + this License applicable to that copy. + + 3. Object Code Incorporating Material from Library Header Files. + + The object code form of an Application may incorporate material from +a header file that is part of the Library. You may convey such object +code under terms of your choice, provided that, if the incorporated +material is not limited to numerical parameters, data structure +layouts and accessors, or small macros, inline functions and templates +(ten or fewer lines in length), you do both of the following: + + a) Give prominent notice with each copy of the object code that the + Library is used in it and that the Library and its use are + covered by this License. + + b) Accompany the object code with a copy of the GNU GPL and this license + document. + + 4. Combined Works. + + You may convey a Combined Work under terms of your choice that, +taken together, effectively do not restrict modification of the +portions of the Library contained in the Combined Work and reverse +engineering for debugging such modifications, if you also do each of +the following: + + a) Give prominent notice with each copy of the Combined Work that + the Library is used in it and that the Library and its use are + covered by this License. + + b) Accompany the Combined Work with a copy of the GNU GPL and this license + document. + + c) For a Combined Work that displays copyright notices during + execution, include the copyright notice for the Library among + these notices, as well as a reference directing the user to the + copies of the GNU GPL and this license document. + + d) Do one of the following: + + 0) Convey the Minimal Corresponding Source under the terms of this + License, and the Corresponding Application Code in a form + suitable for, and under terms that permit, the user to + recombine or relink the Application with a modified version of + the Linked Version to produce a modified Combined Work, in the + manner specified by section 6 of the GNU GPL for conveying + Corresponding Source. + + 1) Use a suitable shared library mechanism for linking with the + Library. A suitable mechanism is one that (a) uses at run time + a copy of the Library already present on the user's computer + system, and (b) will operate properly with a modified version + of the Library that is interface-compatible with the Linked + Version. + + e) Provide Installation Information, but only if you would otherwise + be required to provide such information under section 6 of the + GNU GPL, and only to the extent that such information is + necessary to install and execute a modified version of the + Combined Work produced by recombining or relinking the + Application with a modified version of the Linked Version. (If + you use option 4d0, the Installation Information must accompany + the Minimal Corresponding Source and Corresponding Application + Code. If you use option 4d1, you must provide the Installation + Information in the manner specified by section 6 of the GNU GPL + for conveying Corresponding Source.) + + 5. Combined Libraries. + + You may place library facilities that are a work based on the +Library side by side in a single library together with other library +facilities that are not Applications and are not covered by this +License, and convey such a combined library under terms of your +choice, if you do both of the following: + + a) Accompany the combined library with a copy of the same work based + on the Library, uncombined with any other library facilities, + conveyed under the terms of this License. + + b) Give prominent notice with the combined library that part of it + is a work based on the Library, and explaining where to find the + accompanying uncombined form of the same work. + + 6. Revised Versions of the GNU Lesser General Public License. + + The Free Software Foundation may publish revised and/or new versions +of the GNU Lesser General Public License from time to time. Such new +versions will be similar in spirit to the present version, but may +differ in detail to address new problems or concerns. + + Each version is given a distinguishing version number.

If the Library as you +received it does not specify a version number of the GNU Lesser +General Public License, you may choose any version of the GNU Lesser +General Public License ever published by the Free Software Foundation. + + If the Library as you received it specifies that a proxy can decide +whether future versions of the GNU Lesser General Public License shall +apply, that proxy's public statement of acceptance of any version is +permanent authorization for you to choose that version for the +Library. diff --git a/Makefile b/Makefile new file mode 100644 index

0096/2055] Add Python 3.9 Docker image for CI MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Experimentally add the latest Python 3.9 Docker image for unit test and nightly test runs. This currently uses the Python 3.9a1 version but might automatically move to a later alpha or beta version as soon as they are released and the according Docker file was adjusted on Docker Hub. We activate this as an experiment, and also to make sure that you implementation won't break as soon as Python 3.9 will be released. According to the release schedule [1], the beta phase of Python 3.9 is planned to start on 2020–05–18 and the release candidate phase is planned to start on 2020–08–10. There is not yet a planned date for the final release of Python 3.9. This is truly an experiment, which might fail. In case we suffer from issues with Python 3.9, we might need to revert this commit and re-add the changes later. --- .gitlab-ci.yml | 10 ++++++++++ 1 file changed, 10 insertions(+) diff --git a/.gitlab-ci.yml b/.gitlab-ci.yml index 75e25462a..4353cc562 100644 --- a/.gitlab-ci.yml +++ b/.gitlab-ci.yml @@ -23,6 +23,11 @@ unit-tests:python-3.8: variables: PYTHON_VERSION: '3.8-buster' +unit-tests:python-3.9: + <<: *unit-tests + variables: + PYTHON_VERSION: '3.9-rc-buster' + .nightly-tests: only: - schedules @@ -40,6 +45,11 @@ nightly-tests:python-3.8: variables: PYTHON_VERSION: '3.8-buster' +nightly-tests:python-3.9: + extends: .nightly-tests + variables: + PYTHON_VERSION: '3.9-rc-buster' + flake8: stage: build image: python:3.8 From 6b24bab6d7a5d9af945176eb4fe4cf67b3442663 Mon Sep 17 00:00:00 2001 From: Stephan Lukasczyk Date: Thu, 19 Dec 2019 16:40:52 +0100 Subject: [PATCH 0097/2055] Revert "Add Python 3.9 Docker image for CI" This reverts commit d532788d18e76ebd84beff1637f11c3d2c2880d3.

From eea16449f9cb87bc840cda2e72691a0df231855e Mon Sep 17 00:00:00 2001 From: Stephan Lukasczyk Date: Wed, 22 Jan 2020 15:34:56 +0100 Subject: [PATCH 0157/2055] Extract fixtures for module imports Working with real modules is necessary for a couple of tests of the generation algorithms. Thus we create fixtures for the usage. Both fixtures are meant to be session-wide, i.e., their effect is only done once. This should not be a problem but more efficient, since it avoids the reloading of modules for each and every test case. It should not be a problem as long as we only do read accesses on the fixture's return values. The fixtures purpose are the following: - provide_imported_modules returns a dictionary of module names and the imported module content; the module name is only the last path of the fully-qualified name, thus be careful to not introduce duplicates when extending this fixture. - provide_callables_from_fixtures_modules returns a dictionary of callable name to callable, which provides access to all classes, methods, and functions of the modules defined in the `provide_imported_modules` fixture. Take care that there are no duplicate names for the callable names within the modules when you extend the modules! --- tests/conftest.py | 39 ++++++++++++++++++- .../algorithms/randoopy/test_algorithm.py | 31 +++++++-------- 2 files changed, 52 insertions(+), 18 deletions(-) diff --git a/tests/conftest.py b/tests/conftest.py index e5420f844..fab60285e 100644 --- a/tests/conftest.py +++ b/tests/conftest.py @@ -12,7 +12,10 @@ # # You should have received a copy of the GNU Lesser General Public License # along with Pynguin.

The tests now also have an automatic fixture that resets the configuration to some default values. The required parameters are now also the absolute minimum to run pynguin. Removed configargparse and added simple-parsing. Why: This removes the need to pass the configuration around to every object which needs some information from it.

The raising statements where covered, however, thus should also be part of the coverage value. Note that this change introduces a difference on purpose!

Previously, we could not handle them properly at all. If we had a signature such as `foo(*args, **kwargs)`, we generated two argument values for the two arguments—which is conceptually wrong, since `*args` accepts a list of arguments of undefined length and `**kwargs` accepts keyworded arguments. This change now skips those types explicitly, i.e., it does not generate argument values for these. It only logs their appearance and continues with the next parameter. This should be implemented in the future, together with the handling of lists, sets, and dictionaries. --- pynguin/testcase/testfactory.py | 27 ++++++++++++++++++++------- 1 file changed, 20 insertions(+), 7 deletions(-) diff --git a/pynguin/testcase/testfactory.py b/pynguin/testcase/testfactory.py index bcbdfe915..e7f23d1f0 100644 --- a/pynguin/testcase/testfactory.py +++ b/pynguin/testcase/testfactory.py @@ -15,6 +15,7 @@ """Provides a factory for test-case generation.""" from __future__ import annotations +import inspect import logging from typing import List, Type, Optional, Dict, Set, cast @@ -29,6 +30,7 @@ import pynguin.testcase.variable.variablereference as vr import pynguin.utils.generic.genericaccessibleobject as gao from pynguin.setup.testcluster import TestCluster +from pynguin.typeinference.strategy import InferredSignature from pynguin.utils import randomness from pynguin.utils.exceptions import ConstructionFailedException from pynguin.utils.generic.genericaccessibleobject import GenericAccessibleObject @@ -174,7 +176,7 @@ def add_constructor( try: parameters: List[vr.VariableReference] = self.satisfy_parameters( test_case=test_case, - parameter_types=signature.parameters, + signature=signature, position=position, recursion_depth=recursion_depth + 1, allow_none=allow_none, @@ -233,7 +235,7 @@ def add_method( assert callee, "The callee must not be None" parameters: List[vr.VariableReference] = self.satisfy_parameters( test_case=test_case, - parameter_types=signature.parameters, + signature=signature, position=position, recursion_depth=recursion_depth + 1, allow_none=allow_none, @@ -322,7 +324,7 @@ def add_function( length = test_case.size() parameters: List[vr.VariableReference] = self.satisfy_parameters( test_case=test_case, - parameter_types=signature.parameters, + signature=signature, position=position, recursion_depth=recursion_depth + 1, allow_none=allow_none, @@ -692,7 +694,7 @@ def _dependencies_satisfied( def satisfy_parameters( self, test_case: tc.TestCase, - parameter_types: Dict[str, Optional[Type]], + signature: InferredSignature, callee: Optional[vr.VariableReference] = None, position: int = -1, recursion_depth: int = 0, @@ -702,7 +704,7 @@ def satisfy_parameters( """Satisfy a list of parameters by reusing or creating variables. :param test_case: The test case - :param parameter_types: The list of parameter types + :param signature: The inferred signature of the method :param callee: The callee of the method :param position: The current position in the test case :param recursion_depth: The recursion depth @@ -717,14 +719,25 @@ def satisfy_parameters( parameters: List[vr.VariableReference] = [] self._logger.debug( "Trying to satisfy %d parameters at position %d", - len(parameter_types), + len(signature.parameters), position, ) - for _, parameter_type in parameter_types.items(): + for parameter_name, parameter_type in signature.parameters.items(): self._logger.debug("Current parameter type: %s", parameter_type) previous_length = test_case.size() + parameter: inspect.Parameter = signature.signature.parameters[ + parameter_name + ] + if parameter.kind == inspect.Parameter.VAR_POSITIONAL: + self._logger.info("Skip variational parameter %s", parameter_name) + # TODO Implement generation for positional parameters of variable length + continue + if parameter.kind == inspect.Parameter.VAR_KEYWORD: + self._logger.info("Skip keyword parameter %s", parameter_name) + # TODO Implement generation for keyword parameters of variable length + continue if can_reuse_existing_variables: self._logger.debug("Can re-use variables") From 66f01b9b241b36c7a12092da03e8d0c6c643c8ac Mon Sep 17 00:00:00 2001 From: Florian Kroiss Date: Fri, 27 Mar 2020 19:17:55 +0100 Subject: [PATCH 0506/2055] ParametrizedStatement: Add tests for mutation related methods.

Otherwise, one needs to subtract the failing size and length from the non-failing numbers during analysis, to achieve the correct results. --- pynguin/generator.py | 10 +++++----- 1 file changed, 5 insertions(+), 5 deletions(-) diff --git a/pynguin/generator.py b/pynguin/generator.py index 23e6bfe02..df663617c 100644 --- a/pynguin/generator.py +++ b/pynguin/generator.py @@ -219,7 +219,7 @@ def _run(self) -> int: failing.test_chromosomes, "_failing", wrap_code=True ) - self._track_statistics(combined, failing) + self._track_statistics(non_failing, failing) self._collect_statistics() if not StatisticsTracker().write_statistics(): self._logger.error("Failed to write statistics data") @@ -261,13 +261,13 @@ def _collect_statistics() -> None: @staticmethod def _track_statistics( - combined: tsc.TestSuiteChromosome, failing: tsc.TestSuiteChromosome, + non_failing: tsc.TestSuiteChromosome, failing: tsc.TestSuiteChromosome, ) -> None: tracker = StatisticsTracker() - tracker.current_individual(combined) - tracker.track_output_variable(RuntimeVariable.Size, combined.size()) + tracker.current_individual(non_failing) + tracker.track_output_variable(RuntimeVariable.Size, non_failing.size()) tracker.track_output_variable( - RuntimeVariable.Length, combined.total_length_of_test_cases + RuntimeVariable.Length, non_failing.total_length_of_test_cases ) tracker.track_output_variable(RuntimeVariable.FailingSize, failing.size()) tracker.track_output_variable( From d3c64670d3137a982a289c8dc92f1ebf269976db Mon Sep 17 00:00:00 2001 From: Florian Kroiss Date: Thu, 23 Apr 2020 11:25:50 +0200 Subject: [PATCH 0621/2055] Update dependencies --- poetry.lock | 6 +++--- 1 file changed, 3 insertions(+), 3 deletions(-) diff --git a/poetry.lock b/poetry.lock index cb2dfc764..d2601b265 100644 --- a/poetry.lock +++ b/poetry.lock @@ -142,7 +142,7 @@ description = "A library for property-based testing" name = "hypothesis" optional = false python-versions = ">=3.5.2" -version = "5.10.1" +version = "5.10.3" [package.dependencies] attrs = ">=19.2.0" @@ -612,8 +612,8 @@ execnet = [ {file = "execnet-1.7.1.tar.gz", hash = "sha256:cacb9df31c9680ec5f95553976c4da484d407e85e41c83cb812aa014f0eddc50"}, ] hypothesis = [ - {file = "hypothesis-5.10.1-py3-none-any.whl", hash = "sha256:2c33b1f50bbe6eaa2d4b45f125c40957fbc479d20b631f9717963eb589974a7a"}, - {file = "hypothesis-5.10.1.tar.gz", hash = "sha256:790acebcd8445fbc897b0f1a8e1e29ec4f476e6fdb64692c13c14b1e4f3c178d"}, + {file = "hypothesis-5.10.3-py3-none-any.whl", hash = "sha256:f59a16be1184af7cf0052f58d1b1ac2c0ddd0858a73f5cc8de48294c96000bdb"}, + {file = "hypothesis-5.10.3.tar.gz", hash = "sha256:f37b5c90e2922b4d2a129690ee11735f94bd714ec13b5ee2ae2317c5a3304735"}, ] isort = [ {file = "isort-4.3.21-py2.py3-none-any.whl", hash = "sha256:6e811fcb295968434526407adb8796944f1988c5b65e8139058f2014cbe100fd"}, From 7d844c3c0c23460ed2cd6cb44c32c5c1ab492979 Mon Sep 17 00:00:00 2001 From: Florian Kroiss Date: Thu, 23 Apr 2020 12:19:27 +0200 Subject: [PATCH 0622/2055] ExecutionTracer: Improve debugging capabilities.

Only methods that are defined in a particular class should be, together with overridden methods. This change provides a regression test case exposing the issue, where before it `__iter__` method was added to the methods of class `Bar`, although only being inherited from `Foo`; it was furthermore not part of the available methods of `Foo`. The implementation now checks whether a method was defined in the currently inspected class, if not it will not be added to the cluster. Furthermore, we provide a small readability refactoring for the skip conditions. --- pynguin/setup/testclustergenerator.py | 27 +++++++++++++--- pynguin/utils/type_utils.py | 24 ++++++++++++++ .../cluster/overridden_inherited_methods.py | 31 +++++++++++++++++++ tests/setup/test_testclustergenerator.py | 25 ++++++++++++++- 4 files changed, 101 insertions(+), 6 deletions(-) create mode 100644 tests/fixtures/cluster/overridden_inherited_methods.py diff --git a/pynguin/setup/testclustergenerator.py b/pynguin/setup/testclustergenerator.py index f2c8eee7e..3959e7a00 100644 --- a/pynguin/setup/testclustergenerator.py +++ b/pynguin/setup/testclustergenerator.py @@ -40,6 +40,7 @@ is_primitive_type, class_in_module, function_in_module, + get_class_that_defined_method, ) @@ -160,11 +161,15 @@ def _add_dependency(self, klass: Type, recursion_level: int, add_to_test: bool): for method_name, method in inspect.getmembers(klass, inspect.isfunction): # TODO(fk) why does inspect.ismethod not work here?! self._logger.debug("Analyzing method %s", method_name) - if method_name == "__init__": - # The constructor is handled elsewhere. - continue - if method_name.startswith("_") and not method_name.startswith("__"): - self._logger.debug("Skip private method %s", method_name) + if ( + self._is_constructor(method_name) + or not self._is_method_defined_in_class(klass, method) + or self._is_private_method(method_name) + ): + # Skip methods that should not be added to the cluster here. + # Constructors are handled elsewhere; inherited methods should not be + # part of the cluster, only overridden methods; private methods should + # neither be part of the cluster. continue generic_method = GenericMethod( @@ -177,6 +182,18 @@ def _add_dependency(self, klass: Type, recursion_level: int, add_to_test: bool): self._add_callable_dependencies(generic_method, recursion_level) # TODO(fk) how do we find attributes? + @staticmethod + def _is_constructor(method_name: str) -> bool: + return method_name == "__init__" + + @staticmethod + def _is_method_defined_in_class(class_: type, method: object) -> bool: + return class_ == get_class_that_defined_method(method) + + @staticmethod + def _is_private_method(method_name: str) -> bool: + return method_name.startswith("_") and not method_name.startswith("__") + def _resolve_dependencies_recursive(self): """Resolve the currently open dependencies.""" while self._dependencies_to_solve: diff --git a/pynguin/utils/type_utils.py b/pynguin/utils/type_utils.py index b13fe059d..8a24a1582 100644 --- a/pynguin/utils/type_utils.py +++ b/pynguin/utils/type_utils.py @@ -13,6 +13,7 @@ # You should have received a copy of the GNU Lesser General Public License # along with Pynguin.

Our CFG generation then takes this and adds a node to the CFG that has no predecessor but only the jump target as a successor. The underlying assumption and invariant on the CFG is that there is only one entry node. The above produces further entry nodes, which then let the computation of, e.g., dominator trees fail. We now assume all nodes that have no predecessors and do not have the index 0, i.e., that are not the original method entry, dead code and remove them from the graph. --- pynguin/analyses/controlflow/cfg.py | 13 +++++++++++++ 1 file changed, 13 insertions(+) diff --git a/pynguin/analyses/controlflow/cfg.py b/pynguin/analyses/controlflow/cfg.py index 918b96928..68272634f 100644 --- a/pynguin/analyses/controlflow/cfg.py +++ b/pynguin/analyses/controlflow/cfg.py @@ -51,6 +51,9 @@ def from_bytecode(bytecode: Bytecode) -> CFG: # Insert all edges between the previously generated nodes CFG._create_graph(cfg, edges, nodes) + # Filter all dead-code nodes + cfg = CFG._filter_dead_code_nodes(cfg) + # Insert dummy exit node cfg = CFG._insert_dummy_exit_node(cfg) return cfg @@ -149,6 +152,16 @@ def _insert_dummy_exit_node(cfg: CFG) -> CFG: cfg.add_edge(exit_node, dummy_exit_node) return cfg + @staticmethod + def _filter_dead_code_nodes(graph: CFG) -> CFG: + for node in graph.nodes: + if graph.get_predecessors(node) == set() and node.index != 0: + # The only node in the graph that is allowed to have no predecessor + # is the entry node, i.e., the node with index 0.

The particular version of the Library +with which the Combined Work was made is also called the "Linked +Version". + +The "Minimal Corresponding Source" for a Combined Work means the +Corresponding Source for the Combined Work, excluding any source code +for portions of the Combined Work that, considered in isolation, are +based on the Application, and not on the Linked Version. + +The "Corresponding Application Code" for a Combined Work means the +object code and/or source code for the Application, including any data +and utility programs needed for reproducing the Combined Work from the +Application, but excluding the System Libraries of the Combined Work. + +1. Exception to Section 3 of the GNU GPL +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + +You may convey a covered work under sections 3 and 4 of this License +without being bound by section 3 of the GNU GPL. + +2. Conveying Modified Versions +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + +If you modify a copy of the Library, and, in your modifications, a +facility refers to a function or data to be supplied by an Application +that uses the facility (other than as an argument passed when the +facility is invoked), then you may convey a copy of the modified +version: + +* **a)** under this License, provided that you make a good faith effort to + ensure that, in the event an Application does not supply the + function or data, the facility still operates, and performs + whatever part of its purpose remains meaningful, or + +* **b)** under the GNU GPL, with none of the additional permissions of + this License applicable to that copy. + +3. Object Code Incorporating Material from Library Header Files +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + +The object code form of an Application may incorporate material from +a header file that is part of the Library. You may convey such object +code under terms of your choice, provided that, if the incorporated +material is not limited to numerical parameters, data structure +layouts and accessors, or small macros, inline functions and templates +(ten or fewer lines in length), you do both of the following: + +* **a)** Give prominent notice with each copy of the object code that the + Library is used in it and that the Library and its use are + covered by this License. +* **b)** Accompany the object code with a copy of the GNU GPL and this license + document. + +4. Combined Works +~~~~~~~~~~~~~~~~~ + +You may convey a Combined Work under terms of your choice that, +taken together, effectively do not restrict modification of the +portions of the Library contained in the Combined Work and reverse +engineering for debugging such modifications, if you also do each of +the following: + +* **a)** Give prominent notice with each copy of the Combined Work that + the Library is used in it and that the Library and its use are + covered by this License. + +* **b)** Accompany the Combined Work with a copy of the GNU GPL and this license + document. + +* **c)** For a Combined Work that displays copyright notices during + execution, include the copyright notice for the Library among + these notices, as well as a reference directing the user to the + copies of the GNU GPL and this license document. + +* **d)** Do one of the following: + + - **0)** Convey the Minimal Corresponding Source under the terms of this + License, and the Corresponding Application Code in a form + suitable for, and under terms that permit, the user to + recombine or relink the Application with a modified version of + the Linked Version to produce a modified Combined Work, in the + manner specified by section 6 of the GNU GPL for conveying + Corresponding Source. + - **1)** Use a suitable shared library mechanism for linking with the + Library. A suitable mechanism is one that **(a)** uses at run time + a copy of the Library already present on the user's computer + system, and **(b)** will operate properly with a modified version + of the Library that is interface-compatible with the Linked + Version. + +* **e)** Provide Installation Information, but only if you would otherwise + be required to provide such information under section 6 of the + GNU GPL, and only to the extent that such information is + necessary to install and execute a modified version of the + Combined Work produced by recombining or relinking the + Application with a modified version of the Linked Version. (If + you use option **4d0**, the Installation Information must accompany + the Minimal Corresponding Source and Corresponding Application + Code. If you use option **4d1**, you must provide the Installation + Information in the manner specified by section 6 of the GNU GPL + for conveying Corresponding Source.) + +5. Combined Libraries +~~~~~~~~~~~~~~~~~~~~~ + +You may place library facilities that are a work based on the +Library side by side in a single library together with other library +facilities that are not Applications and are not covered by this +License, and convey such a combined library under terms of your +choice, if you do both of the following: + +* **a)** Accompany the combined library with a copy of the same work based + on the Library, uncombined with any other library facilities, + conveyed under the terms of this License. +* **b)** Give prominent notice with the combined library that part of it + is a work based on the Library, and explaining where to find the + accompanying uncombined form of the same work. + +6. Revised Versions of the GNU Lesser General Public License +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + +The Free Software Foundation may publish revised and/or new versions +of the GNU Lesser General Public License from time to time. Such new +versions will be similar in spirit to the present version, but may +differ in detail to address new problems or concerns. + +Each version is given a distinguishing version number. If the +Library as you received it specifies that a certain numbered version +of the GNU Lesser General Public License "or any later version" +applies to it, you have the option of following the terms and +conditions either of that published version or of any later version +published by the Free Software Foundation. If the Library as you +received it does not specify a version number of the GNU Lesser +General Public License, you may choose any version of the GNU Lesser +General Public License ever published by the Free Software Foundation. + +If the Library as you received it specifies that a proxy can decide +whether future versions of the GNU Lesser General Public License shall +apply, that proxy's public statement of acceptance of any version is +permanent authorization for you to choose that version for the +Library.

Conveying Modified Versions -~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ - -If you modify a copy of the Library, and, in your modifications, a -facility refers to a function or data to be supplied by an Application -that uses the facility (other than as an argument passed when the -facility is invoked), then you may convey a copy of the modified -version: - -* **a)** under this License, provided that you make a good faith effort to - ensure that, in the event an Application does not supply the - function or data, the facility still operates, and performs - whatever part of its purpose remains meaningful, or - -* **b)** under the GNU GPL, with none of the additional permissions of - this License applicable to that copy. - -3. Object Code Incorporating Material from Library Header Files -~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ - -The object code form of an Application may incorporate material from -a header file that is part of the Library. You may convey such object -code under terms of your choice, provided that, if the incorporated -material is not limited to numerical parameters, data structure -layouts and accessors, or small macros, inline functions and templates -(ten or fewer lines in length), you do both of the following: - -* **a)** Give prominent notice with each copy of the object code that the - Library is used in it and that the Library and its use are - covered by this License. -* **b)** Accompany the object code with a copy of the GNU GPL and this license - document. - -4. Combined Works -~~~~~~~~~~~~~~~~~ - -You may convey a Combined Work under terms of your choice that, -taken together, effectively do not restrict modification of the -portions of the Library contained in the Combined Work and reverse -engineering for debugging such modifications, if you also do each of -the following: - -* **a)** Give prominent notice with each copy of the Combined Work that - the Library is used in it and that the Library and its use are - covered by this License. - -* **b)** Accompany the Combined Work with a copy of the GNU GPL and this license - document. - -* **c)** For a Combined Work that displays copyright notices during - execution, include the copyright notice for the Library among - these notices, as well as a reference directing the user to the - copies of the GNU GPL and this license document. - -* **d)** Do one of the following: - - - **0)** Convey the Minimal Corresponding Source under the terms of this - License, and the Corresponding Application Code in a form - suitable for, and under terms that permit, the user to - recombine or relink the Application with a modified version of - the Linked Version to produce a modified Combined Work, in the - manner specified by section 6 of the GNU GPL for conveying - Corresponding Source. - - **1)** Use a suitable shared library mechanism for linking with the - Library. A suitable mechanism is one that **(a)** uses at run time - a copy of the Library already present on the user's computer - system, and **(b)** will operate properly with a modified version - of the Library that is interface-compatible with the Linked - Version. - -* **e)** Provide Installation Information, but only if you would otherwise - be required to provide such information under section 6 of the - GNU GPL, and only to the extent that such information is - necessary to install and execute a modified version of the - Combined Work produced by recombining or relinking the - Application with a modified version of the Linked Version. (If - you use option **4d0**, the Installation Information must accompany - the Minimal Corresponding Source and Corresponding Application - Code. If you use option **4d1**, you must provide the Installation - Information in the manner specified by section 6 of the GNU GPL - for conveying Corresponding Source.) - -5. Combined Libraries -~~~~~~~~~~~~~~~~~~~~~ - -You may place library facilities that are a work based on the -Library side by side in a single library together with other library -facilities that are not Applications and are not covered by this -License, and convey such a combined library under terms of your -choice, if you do both of the following: - -* **a)** Accompany the combined library with a copy of the same work based - on the Library, uncombined with any other library facilities, - conveyed under the terms of this License. -* **b)** Give prominent notice with the combined library that part of it - is a work based on the Library, and explaining where to find the - accompanying uncombined form of the same work. - -6. Revised Versions of the GNU Lesser General Public License -~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ - -The Free Software Foundation may publish revised and/or new versions -of the GNU Lesser General Public License from time to time. Such new -versions will be similar in spirit to the present version, but may -differ in detail to address new problems or concerns. - -Each version is given a distinguishing version number. If the -Library as you received it specifies that a certain numbered version -of the GNU Lesser General Public License "or any later version" -applies to it, you have the option of following the terms and -conditions either of that published version or of any later version -published by the Free Software Foundation. If the Library as you -received it does not specify a version number of the GNU Lesser -General Public License, you may choose any version of the GNU Lesser -General Public License ever published by the Free Software Foundation. - -If the Library as you received it specifies that a proxy can decide -whether future versions of the GNU Lesser General Public License shall -apply, that proxy's public statement of acceptance of any version is -permanent authorization for you to choose that version for the -Library. diff --git a/docs/source/_static/example-stdout.txt b/docs/source/_static/example-stdout.txt new file mode 100644 index 000000000..6096ca6e5 --- /dev/null +++ b/docs/source/_static/example-stdout.txt @@ -0,0 +1,108 @@ +[INFO](pynguin.generator): Start Pynguin Test Generation… +[INFO](pynguin.generator): No seed given.

To the extent this Public +License may be interpreted as a contract, You are granted the Licensed Rights +in consideration of Your acceptance of these terms and conditions, and the +Licensor grants You such rights in consideration of benefits the Licensor +receives from making the Licensed Material available under these terms and +conditions. + +Section 1 – Definitions. + +a. Adapted Material means material subject to Copyright and Similar Rights +that is derived from or based upon the Licensed Material and in which the +Licensed Material is translated, altered, arranged, transformed, or otherwise +modified in a manner requiring permission under the Copyright and Similar +Rights held by the Licensor. For purposes of this Public License, where the +Licensed Material is a musical work, performance, or sound recording, Adapted +Material is always produced where the Licensed Material is synched in timed +relation with a moving image. + +b. Adapter's License means the license You apply to Your Copyright and Similar +Rights in Your contributions to Adapted Material in accordance with the terms +and conditions of this Public License. + +c. Copyright and Similar Rights means copyright and/or similar rights closely +related to copyright including, without limitation, performance, broadcast, +sound recording, and Sui Generis Database Rights, without regard to how the +rights are labeled or categorized. For purposes of this Public License, the +rights specified in Section 2(b)(1)-(2) are not Copyright and Similar Rights. + +d. Effective Technological Measures means those measures that, in the absence +of proper authority, may not be circumvented under laws fulfilling obligations +under Article 11 of the WIPO Copyright Treaty adopted on December 20, 1996, +and/or similar international agreements. + +e. Exceptions and Limitations means fair use, fair dealing, and/or any other +exception or limitation to Copyright and Similar Rights that applies to Your +use of the Licensed Material. + +f. Licensed Material means the artistic or literary work, database, or other +material to which the Licensor applied this Public License. + +g. Licensed Rights means the rights granted to You subject to the terms and +conditions of this Public License, which are limited to all Copyright and +Similar Rights that apply to Your use of the Licensed Material and that the +Licensor has authority to license. + +h. Licensor means the individual(s) or entity(ies) granting rights under this +Public License. + +i. Share means to provide material to the public by any means or process that +requires permission under the Licensed Rights, such as reproduction, public +display, public performance, distribution, dissemination, communication, or +importation, and to make material available to the public including in ways +that members of the public may access the material from a place and at a time +individually chosen by them. + +j. Sui Generis Database Rights means rights other than copyright resulting +from Directive 96/9/EC of the European Parliament and of the Council of 11 +March 1996 on the legal protection of databases, as amended and/or succeeded, +as well as other essentially equivalent rights anywhere in the world. + +k. You means the individual or entity exercising the Licensed Rights under +this Public License. Your has a corresponding meaning. + +Section 2 – Scope. + + a. License grant. + +1. Subject to the terms and conditions of this Public License, the Licensor +hereby grants You a worldwide, royalty-free, non-sublicensable, non-exclusive, +irrevocable license to exercise the Licensed Rights in the Licensed Material +to: + + A. reproduce and Share the Licensed Material, in whole or in part; and + + B. produce, reproduce, and Share Adapted Material. + +2. Exceptions and Limitations. For the avoidance of doubt, where Exceptions +and Limitations apply to Your use, this Public License does not apply, and +You do not need to comply with its terms and conditions. + + 3. Term. The term of this Public License is specified in Section 6(a). + +4. Media and formats; technical modifications allowed. The Licensor authorizes +You to exercise the Licensed Rights in all media and formats whether now known +or hereafter created, and to make technical modifications necessary to do +so. The Licensor waives and/or agrees not to assert any right or authority +to forbid You from making technical modifications necessary to exercise the +Licensed Rights, including technical modifications necessary to circumvent +Effective Technological Measures. For purposes of this Public License, simply +making modifications authorized by this Section 2(a)(4) never produces Adapted +Material. + + 5. Downstream recipients. + +A. Offer from the Licensor – Licensed Material. Every recipient of the Licensed +Material automatically receives an offer from the Licensor to exercise the +Licensed Rights under the terms and conditions of this Public License. + +B. No downstream restrictions. You may not offer or impose any additional +or different terms or conditions on, or apply any Effective Technological +Measures to, the Licensed Material if doing so restricts exercise of the Licensed +Rights by any recipient of the Licensed Material. + +6. No endorsement. Nothing in this Public License constitutes or may be construed +as permission to assert or imply that You are, or that Your use of the Licensed +Material is, connected with, or sponsored, endorsed, or granted official status +by, the Licensor or others designated to receive attribution as provided in +Section 3(a)(1)(A)(i). + + b. Other rights. + +1. Moral rights, such as the right of integrity, are not licensed under this +Public License, nor are publicity, privacy, and/or other similar personality +rights; however, to the extent possible, the Licensor waives and/or agrees +not to assert any such rights held by the Licensor to the limited extent necessary +to allow You to exercise the Licensed Rights, but not otherwise. + +2. Patent and trademark rights are not licensed under this Public License. + +3. To the extent possible, the Licensor waives any right to collect royalties +from You for the exercise of the Licensed Rights, whether directly or through +a collecting society under any voluntary or waivable statutory or compulsory +licensing scheme. In all other cases the Licensor expressly reserves any right +to collect such royalties. + +Section 3 – License Conditions. + +Your exercise of the Licensed Rights is expressly made subject to the following +conditions. + + a. Attribution. + +1. If You Share the Licensed Material (including in modified form), You must: + +A. retain the following if it is supplied by the Licensor with the Licensed +Material: + +i. identification of the creator(s) of the Licensed Material and any others +designated to receive attribution, in any reasonable manner requested by the +Licensor (including by pseudonym if designated); + + ii. a copyright notice; + + iii. a notice that refers to this Public License; + + iv. a notice that refers to the disclaimer of warranties; + +v. a URI or hyperlink to the Licensed Material to the extent reasonably practicable; + +B. indicate if You modified the Licensed Material and retain an indication +of any previous modifications; and + +C. indicate the Licensed Material is licensed under this Public License, and +include the text of, or the URI or hyperlink to, this Public License. + +2. You may satisfy the conditions in Section 3(a)(1) in any reasonable manner +based on the medium, means, and context in which You Share the Licensed Material. +For example, it may be reasonable to satisfy the conditions by providing a +URI or hyperlink to a resource that includes the required information. + +3. If requested by the Licensor, You must remove any of the information required +by Section 3(a)(1)(A) to the extent reasonably practicable. + +4. If You Share Adapted Material You produce, the Adapter's License You apply +must not prevent recipients of the Adapted Material from complying with this +Public License. + +Section 4 – Sui Generis Database Rights. + +Where the Licensed Rights include Sui Generis Database Rights that apply to +Your use of the Licensed Material: + +a. for the avoidance of doubt, Section 2(a)(1) grants You the right to extract, +reuse, reproduce, and Share all or a substantial portion of the contents of +the database; + +b. if You include all or a substantial portion of the database contents in +a database in which You have Sui Generis Database Rights, then the database +in which You have Sui Generis Database Rights (but not its individual contents) +is Adapted Material; and + +c. You must comply with the conditions in Section 3(a) if You Share all or +a substantial portion of the contents of the database. + +For the avoidance of doubt, this Section 4 supplements and does not replace +Your obligations under this Public License where the Licensed Rights include +other Copyright and Similar Rights. + +Section 5 – Disclaimer of Warranties and Limitation of Liability. + +a. Unless otherwise separately undertaken by the Licensor, to the extent possible, +the Licensor offers the Licensed Material as-is and as-available, and makes +no representations or warranties of any kind concerning the Licensed Material, +whether express, implied, statutory, or other. This includes, without limitation, +warranties of title, merchantability, fitness for a particular purpose, non-infringement, +absence of latent or other defects, accuracy, or the presence or absence of +errors, whether or not known or discoverable. Where disclaimers of warranties +are not allowed in full or in part, this disclaimer may not apply to You. + +b. To the extent possible, in no event will the Licensor be liable to You +on any legal theory (including, without limitation, negligence) or otherwise +for any direct, special, indirect, incidental, consequential, punitive, exemplary, +or other losses, costs, expenses, or damages arising out of this Public License +or use of the Licensed Material, even if the Licensor has been advised of +the possibility of such losses, costs, expenses, or damages. Where a limitation +of liability is not allowed in full or in part, this limitation may not apply +to You. + +c. The disclaimer of warranties and limitation of liability provided above +shall be interpreted in a manner that, to the extent possible, most closely +approximates an absolute disclaimer and waiver of all liability. + +Section 6 – Term and Termination. + +a. This Public License applies for the term of the Copyright and Similar Rights +licensed here. However, if You fail to comply with this Public License, then +Your rights under this Public License terminate automatically. + +b. Where Your right to use the Licensed Material has terminated under Section +6(a), it reinstates: + +1. automatically as of the date the violation is cured, provided it is cured +within 30 days of Your discovery of the violation; or + + 2. upon express reinstatement by the Licensor. + +c. For the avoidance of doubt, this Section 6(b) does not affect any right +the Licensor may have to seek remedies for Your violations of this Public +License. + +d. For the avoidance of doubt, the Licensor may also offer the Licensed Material +under separate terms or conditions or stop distributing the Licensed Material +at any time; however, doing so will not terminate this Public License. + + e. Sections 1, 5, 6, 7, and 8 survive termination of this Public License. + +Section 7 – Other Terms and Conditions. + +a. The Licensor shall not be bound by any additional or different terms or +conditions communicated by You unless expressly agreed. + +b. Any arrangements, understandings, or agreements regarding the Licensed +Material not stated herein are separate from and independent of the terms +and conditions of this Public License. + +Section 8 – Interpretation. + +a. For the avoidance of doubt, this Public License does not, and shall not +be interpreted to, reduce, limit, restrict, or impose conditions on any use +of the Licensed Material that could lawfully be made without permission under +this Public License. + +b. To the extent possible, if any provision of this Public License is deemed +unenforceable, it shall be automatically reformed to the minimum extent necessary +to make it enforceable. If the provision cannot be reformed, it shall be severed +from this Public License without affecting the enforceability of the remaining +terms and conditions. + +c. No term or condition of this Public License will be waived and no failure +to comply consented to unless expressly agreed to by the Licensor. + +d. Nothing in this Public License constitutes or may be interpreted as a limitation +upon, or waiver of, any privileges and immunities that apply to the Licensor +or You, including from the legal processes of any jurisdiction or authority. + +Creative Commons is not a party to its public licenses.

Additional Definitions. + + + +As used herein, "this License" refers to version 3 of the GNU Lesser General +Public License, and the "GNU GPL" refers to version 3 of the GNU General Public +License. + + + +"The Library" refers to a covered work governed by this License, other than +an Application or a Combined Work as defined below. + + + +An "Application" is any work that makes use of an interface provided by the +Library, but which is not otherwise based on the Library. Defining a subclass +of a class defined by the Library is deemed a mode of using an interface provided +by the Library. + + + +A "Combined Work" is a work produced by combining or linking an Application +with the Library. The particular version of the Library with which the Combined +Work was made is also called the "Linked Version". + + + +The "Minimal Corresponding Source" for a Combined Work means the Corresponding +Source for the Combined Work, excluding any source code for portions of the +Combined Work that, considered in isolation, are based on the Application, +and not on the Linked Version. + + + +The "Corresponding Application Code" for a Combined Work means the object +code and/or source code for the Application, including any data and utility +programs needed for reproducing the Combined Work from the Application, but +excluding the System Libraries of the Combined Work. + + 1. Exception to Section 3 of the GNU GPL. + +You may convey a covered work under sections 3 and 4 of this License without +being bound by section 3 of the GNU GPL. + + 2. Conveying Modified Versions. + +If you modify a copy of the Library, and, in your modifications, a facility +refers to a function or data to be supplied by an Application that uses the +facility (other than as an argument passed when the facility is invoked), +then you may convey a copy of the modified version: + +a) under this License, provided that you make a good faith effort to ensure +that, in the event an Application does not supply the function or data, the +facility still operates, and performs whatever part of its purpose remains +meaningful, or + +b) under the GNU GPL, with none of the additional permissions of this License +applicable to that copy. + + 3. Object Code Incorporating Material from Library Header Files. + +The object code form of an Application may incorporate material from a header +file that is part of the Library. You may convey such object code under terms +of your choice, provided that, if the incorporated material is not limited +to numerical parameters, data structure layouts and accessors, or small macros, +inline functions and templates (ten or fewer lines in length), you do both +of the following: + +a) Give prominent notice with each copy of the object code that the Library +is used in it and that the Library and its use are covered by this License. + +b) Accompany the object code with a copy of the GNU GPL and this license document. + + 4. Combined Works. + +You may convey a Combined Work under terms of your choice that, taken together, +effectively do not restrict modification of the portions of the Library contained +in the Combined Work and reverse engineering for debugging such modifications, +if you also do each of the following: + +a) Give prominent notice with each copy of the Combined Work that the Library +is used in it and that the Library and its use are covered by this License. + +b) Accompany the Combined Work with a copy of the GNU GPL and this license +document. + +c) For a Combined Work that displays copyright notices during execution, include +the copyright notice for the Library among these notices, as well as a reference +directing the user to the copies of the GNU GPL and this license document. + + d) Do one of the following: + +0) Convey the Minimal Corresponding Source under the terms of this License, +and the Corresponding Application Code in a form suitable for, and under terms +that permit, the user to recombine or relink the Application with a modified +version of the Linked Version to produce a modified Combined Work, in the +manner specified by section 6 of the GNU GPL for conveying Corresponding Source. + +1) Use a suitable shared library mechanism for linking with the Library. A +suitable mechanism is one that (a) uses at run time a copy of the Library +already present on the user's computer system, and (b) will operate properly +with a modified version of the Library that is interface-compatible with the +Linked Version. + +e) Provide Installation Information, but only if you would otherwise be required +to provide such information under section 6 of the GNU GPL, and only to the +extent that such information is necessary to install and execute a modified +version of the Combined Work produced by recombining or relinking the Application +with a modified version of the Linked Version. (If you use option 4d0, the +Installation Information must accompany the Minimal Corresponding Source and +Corresponding Application Code. If you use option 4d1, you must provide the +Installation Information in the manner specified by section 6 of the GNU GPL +for conveying Corresponding Source.) + + 5. Combined Libraries. + +You may place library facilities that are a work based on the Library side +by side in a single library together with other library facilities that are +not Applications and are not covered by this License, and convey such a combined +library under terms of your choice, if you do both of the following: + +a) Accompany the combined library with a copy of the same work based on the +Library, uncombined with any other library facilities, conveyed under the +terms of this License. + +b) Give prominent notice with the combined library that part of it is a work +based on the Library, and explaining where to find the accompanying uncombined +form of the same work. + + 6. Revised Versions of the GNU Lesser General Public License. + +The Free Software Foundation may publish revised and/or new versions of the +GNU Lesser General Public License from time to time. Such new versions will +be similar in spirit to the present version, but may differ in detail to address +new problems or concerns. + +Each version is given a distinguishing version number. If the Library as you +received it specifies that a certain numbered version of the GNU Lesser General +Public License "or any later version" applies to it, you have the option of +following the terms and conditions either of that published version or of +any later version published by the Free Software Foundation. If the Library +as you received it does not specify a version number of the GNU Lesser General +Public License, you may choose any version of the GNU Lesser General Public +License ever published by the Free Software Foundation. + +If the Library as you received it specifies that a proxy can decide whether +future versions of the GNU Lesser General Public License shall apply, that +proxy's public statement of acceptance of any version is permanent authorization +for you to choose that version for the Library. diff --git a/Makefile b/Makefile index 035adf67a..b2877bd04 100644 --- a/Makefile +++

sub-typing relationship in the type hierarchy. This is a first small version of the mock, it can be extended to provide some kind of symbolic execution/restart for branchings; this would be interesting for all comparison methods, such as `__eq__` or `__lt__`, but also to return a new instance of this duck mock class as a return value of methods to also track the information of those. --- pynguin/utils/duckmock/__init__.py | 6 ++ pynguin/utils/duckmock/duckmock.py | 71 ++++++++++++++++++ tests/utils/duckmock/__init__.py | 6 ++ tests/utils/duckmock/test_duckmock.py | 101 ++++++++++++++++++++++++++ 4 files changed, 184 insertions(+) create mode 100644 pynguin/utils/duckmock/__init__.py create mode 100644 pynguin/utils/duckmock/duckmock.py create mode 100644 tests/utils/duckmock/__init__.py create mode 100644 tests/utils/duckmock/test_duckmock.py diff --git a/pynguin/utils/duckmock/__init__.py b/pynguin/utils/duckmock/__init__.py new file mode 100644 index 000000000..f8d0bb1f9 --- /dev/null +++ b/pynguin/utils/duckmock/__init__.py @@ -0,0 +1,6 @@ +# This file is part of Pynguin. +# +# SPDX-FileCopyrightText: 2019–2020 Pynguin Contributors +# +# SPDX-License-Identifier: LGPL-3.0-or-later +# diff --git a/pynguin/utils/duckmock/duckmock.py b/pynguin/utils/duckmock/duckmock.py new file mode 100644 index 000000000..387d8da52 --- /dev/null +++ b/pynguin/utils/duckmock/duckmock.py @@ -0,0 +1,71 @@ +# This file is part of Pynguin. +# +# SPDX-FileCopyrightText: 2019–2020 Pynguin Contributors +# +# SPDX-License-Identifier: LGPL-3.0-or-later +# +"""Provides an extended version of a mock that can be used for type inference.""" +from dataclasses import dataclass +from typing import Any, Dict, List, Set +from unittest.mock import MagicMock + + +@dataclass(frozen=True, eq=False) +class CallInformation: + """A wrapper to store call information.""" + + name: str + args: List[Any] + kwargs: Dict[str, Any] + + def __eq__(self, other: Any) -> bool: + if self is other: + return True + if not isinstance(other, CallInformation): + return False + return self.name == other.name + + def __hash__(self) -> int: + return 31 + 17 * hash(self.name) + + +class DuckMock(MagicMock): + """Provides an extended version of a mock for type inference. + + The idea of this is to utilise Python's duck-typing abilities, i.e., if a type A + provides certain methods it is considered to be of type B—that is defined by + these methods—even if there is no relationship between A and B in terms of type + hierarchy. + + This mock captures all calls to its methods and allows to query them after + execution.

This design decision came from implementing the random algorithm following Randoop's algorithm. This split never seemed very reasonable, especially since we report the total coverage of all generated tests, independent whether they passed or failed, i.e., raised exceptions, during their execution. This now changes the return type such that a test-generation strategy yields only one test-suite chromosome containing all generated tests. The previous commit introduced a change that allows the splitting in the generator implementation just before exporting the test cases. We, however, do not yet care for test cases that raise exceptions on purpose; we need a special treatment for those test cases during code generation, such that the test case checks for the expected exception. --- .../algorithms/randoopy/randomteststrategy.py | 9 +++-- .../algorithms/testgenerationstrategy.py | 8 ++-- .../algorithms/wspy/wholesuiteteststrategy.py | 40 +++---------------- pynguin/generator.py | 26 +++++------- .../test_integration_randomteststrategy.py | 3 +- .../randoopy/test_randomteststrategy.py | 3 +- ...test_integration_wholesuiteteststrategy.py | 3 +- 7 files changed, 29 insertions(+), 63 deletions(-) diff --git a/pynguin/generation/algorithms/randoopy/randomteststrategy.py b/pynguin/generation/algorithms/randoopy/randomteststrategy.py index 879fad61b..a30f7f5fe 100644 --- a/pynguin/generation/algorithms/randoopy/randomteststrategy.py +++ b/pynguin/generation/algorithms/randoopy/randomteststrategy.py @@ -6,7 +6,7 @@ # """Provides a random test generation algorithm similar to Randoop.""" import logging -from typing import List, Set, Tuple +from typing import List, Set import pynguin.configuration as config import pynguin.ga.testcasechromosome as tcc @@ -35,7 +35,7 @@ def __init__(self, executor: TestCaseExecutor, test_cluster: TestCluster) -> Non def generate_sequences( self, - ) -> Tuple[tsc.TestSuiteChromosome, tsc.TestSuiteChromosome]: + ) -> tsc.TestSuiteChromosome: stopping_condition = self.get_stopping_condition() stopping_condition.reset() test_chromosome: tsc.TestSuiteChromosome = tsc.TestSuiteChromosome() @@ -82,7 +82,10 @@ def generate_sequences( RuntimeVariable.AlgorithmIterations, generation ) - return test_chromosome, failing_test_chromosome + combined_chromosome = self._combine_current_individual( + test_chromosome, failing_test_chromosome + ) + return combined_chromosome def generate_sequence( self, diff --git a/pynguin/generation/algorithms/testgenerationstrategy.py b/pynguin/generation/algorithms/testgenerationstrategy.py index f95f7e5bd..58797f7c2 100644 --- a/pynguin/generation/algorithms/testgenerationstrategy.py +++ b/pynguin/generation/algorithms/testgenerationstrategy.py @@ -62,14 +62,12 @@ def test_factory(self) -> tf.TestFactory: return self._test_factory @abstractmethod - def generate_sequences( - self, - ) -> Tuple[tsc.TestSuiteChromosome, tsc.TestSuiteChromosome]: + def generate_sequences(self) -> tsc.TestSuiteChromosome: """Generates sequences for a given module until the time limit is reached.
