What does this PR do?

See title :)

This PR addresses two problems:

  • missing return
  • writing empty files

missing return

The filter_tests(tests, module=module) call always returned None, because it is missing a return. This None would then cause the fetcher to fail: https://app.circleci.com/pipelines/github/huggingface/transformers/102546/workflows/5e358605-da6b-4c2f-886f-84c9e455a211/jobs/1365782

With this return, the failing job above no longer happens, and CI runs as expected :) (see this PR)

writing empty files

The test fetcher can write empty files for a given job (e.g. test_preparation/tests_torch_and_tf_test_list.txt). This caused a downstream error because:

  • CircleCI skips uploads of empty files (see here, in Uploading artifacts)
  • We trigger a job when there is a file (before upload)
  • The job tried to download a file that didn't exist, causing a failure in the curl step (see here)

As such, this PR changes our test fetcher to skip writing a test file if the file is empty 🤗 No file -> no job -> no problem

thanks! If the test list is empty, we should not even have the job start! I think this was fixed on main by #33220
