This commit introduces a new `pytest.ini` configuration file for backend tests, specifying test discovery patterns and output options. Additionally, the CI workflow is updated to set an environment variable that prevents DeepFace and TensorFlow from loading during tests, avoiding illegal instruction errors on certain CPUs. The face service and pose detection modules are modified to conditionally import DeepFace and RetinaFace based on this environment variable, enhancing test reliability. These changes improve the testing setup and contribute to a more robust CI process.
This commit enhances the CI workflow by adding steps to create test databases and install new testing dependencies, including `pytest`, `httpx`, and `pytest-cov`. Additionally, comprehensive test plan documentation is introduced to outline the structure and best practices for backend API tests. These changes improve the testing environment and contribute to a more robust CI process.
