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.
