Backend Testing Guidelines

• All the tests should test Backend functionalities. Frontend functionalities and e2e tests are done in Frontend.
• Make use of pytest fixtures whenever it is possible. With fixtures, objects with high initialize durations are reused within tests, ex. a client session.
• All testdata resides within _gradio/test_data and all test_files reside within test/test_files.
• When doing network operations do not forget to make use of async to make tests faster.
• Have clear class and function naming within the tests.
• Short descriptions within test functions are great.
• Library function docstrings is expected to contain an example, please add missing docstrings to the library while you are writing tests the related function.
• Library docstring examples and descriptions are expected to align with tests, please fix divergent tests and library docstrings.
