Adding Tests for Examples

You are highly encouraged to add a test for your example so that we will be alerted if it breaks in the future:

  1. Put your test data in the tests folder. The test data can be a few text sentences, images or audio samples
  2. Create test_[your_example].py in the tests folder. Add your test cases to the tests file with meaningful asserts depending on example input and output
  3. Run the test locally to confirm before pushing with pytest
  4. Add your example folder name to the path variable in matrix of .github/worflows/ci.yml. This will trigger your example test on creating a pull request.

Testing Tips

  • For reference, check out the tests folder from any of the examples in this repo.
  • Try using the original example function by importing them to the test. Avoid any modifications to original Flow or logic.
  • Use the pytest fixture tmpdir for temporary directory
