pytest directory structure

Note. Test Directory Structure¶ Salt's test suite is located in the tests/ directory in the root of Salt's codebase. I put the tests next to the package. The tests directory should also contain a requirements.txt file which lists all of the packages that are needed to run the tests. In my case the problem with vscode being unable to discover tests was the coverage module being enabled in the setup.cfg (alternatively this could be a pytest.ini), i.e.. addopts= --cov -ra which caused the test discovery to fail due to low coverage. OpenAI Baselines is a set of high-quality implementations of reinforcement learning algorithms. This is because the deployment project code is independent of the testing code. ¶. The path is interpreted as relative to the working directory when starting pytest. Some people prefer to keep their tests in the same folder as their components. According to its homepage: Pytests may be written either as functions or as methods in classes – unlike unittest, which forces tests to be inside classes. Status: Maintenance (expect bug fixes and minor updates) Baselines. You can either organize our data science file and test file in the same directory or in 2 different directories, one for source code and one for tests.
