+# CTest Framework for NOAA Global Workflow
+
+This directory contains the CTest framework for testing Rocoto JJOBS. The framework allows you to stage, execute, and validate individual JJOBS independently from other jobs in the workflow. Each test requires its own YAML definition of inputs and configurations.
+
+## Overview
+
+The CTest framework consists of the following scripts:
+- **setup.sh.in**: Prepares the environment and creates the experiment.
+- **stage.sh.in**: Stages the input files needed to run a JJOB.
+- **execute.sh.in**: Executes the JJOB and monitors its status.
+- **validate.sh.in**: (TODO) Validates the results of the JJOB.
+
+## Usage
+
+### CMake Configuration
+
+To configure the CTest framework using CMake, you need to provide several environment variables or default values. Here is an example of how to configure and build the project:
+
+```bash
+# Set environment variables (may also be include at command line with -D)
+export HPC_ACCOUNT="your_hpc_account"
+export ICSDIR_ROOT="/path/to/icsdir_root"
+export STAGED_TESTS_DIR="/path/to/staged_tests_dir"
+
+# Run CMake to configure the ctest framework
+cmake -S /path/to/HOMEgfs -B /path/to/build -DRUNTESTS=/path/to/runtests
+
+```
+
+### Running Tests with CTest
+
+Once the project is configured, you can run the tests using CTest. Here are some examples:
+
+#### Run All Tests
+
+```bash
+cd /path/to/build
+ctest
+```
+
+#### Run Tests for a Specific Case
+
+You can use the `-L` option with CTest to run tests for a specific case. For example, to run tests for the `C48_ATM` case:
+
+```bash
+cd /path/to/build
+ctest -L C48_ATM
+```
+
+To add a new test use the **AddJJOBTest()** function at the end of the `$HOMEgfs/ctest/CMakeLists.txt` file as follows:
+```cmake
+AddJJOBTest(
+  CASE "C48_ATM"
+  JOB  "gfs_fcst_seg0"
+  TEST_DATE "2021032312"
+)
+```
+Then create a new YAML file with the required staged input files as is done with this example found in `$HOMEgfs/ctests/cases/C48_ATM_gfs_fcts_seg0.yaml`
