pytest-qgis Compatibility Issue with pytest>=8.0.0 - AssertionError in pytest_addoption

[zacdezgeo]

Hey! I came across your project while testing the https://github.com/gee-community/qgis-earthengine-plugin. It's really helpful, and I got things working with pytest==7.4.3. I wanted to raise the error I got with pytest>=8.

Description:

When using pytest-qgis 2.1.0 with pytest 8.x.x, running tests results in the following error:

Traceback (most recent call last):
  File "/path-to-site-packages/pytest_qgis/pytest_qgis.py", line 120, in pytest_addoption
    parser.addini(
  File "/path-to-site-packages/_pytest/config/argparsing.py", line 178, in addini
    assert type in (None, "pathlist", "args", "linelist", "bool")
AssertionError

The error occurs because pytest-qgis is attempting to register an unsupported type when using the parser.addini() method. This appears to be incompatible with stricter validation rules introduced in pytest>=8.0.0.

---

Expected Behavior:

pytest-qgis should register options with valid types supported by pytest>=8.0.0 without throwing an AssertionError.

---

Potential Fix?

Update the pytest-qgis source code to define the parser.addini() types as valid values (e.g., "args", "linelist"). Example:

parser.addini("qgis_plugins", type="args", help="QGIS plugin paths")

This change would ensure compatibility with pytest>=8.0.0.

Environment Details:

• OS: macOS 13.5
• Python Version: 3.9.5
• pytest Version: 8.3.4
• pytest-qgis Version: 2.1.0
• QGIS Version: 3.28 LTR

Thank you for the issue and apologies for the late reply. I cannot reproduce the error and by observing pytest source code, string and bool are still valid types. I tried to search from the file history if some values were dropped at some point, but I could not found any. Is this error still happening with newest pytest==8.3.5?
