Async tests using anyio are currently skipped. See: https://github.com/huggingface/dataset-viewer/actions/runs/9464138411/job/26070809625

tests/test_authentication.py ssssssssssssssssssssssssssssssssssssssssssssss

After investigation, I found that the issue arose after including pytest-memray by PR:

• https://github.com/huggingface/dataset-viewer/pull/2863
• The issue is caused when passing --memray to pytest: https://github.com/huggingface/dataset-viewer/blob/04f89d8a76e73874c9198c940ad2e61fe71f6f76/tools/PythonTest.mk#L7

I have reported the issue to pytest-memray team:

• https://github.com/bloomberg/pytest-memray/discussions/101#discussioncomment-9738673
• https://github.com/bloomberg/pytest-memray/issues/119

Let's remove --memray I think. I don't think we need it (it only shows a report of the four more memory-consuming tests), we're more interested in specific tests using decorators like @pytest.mark.limit_memory, no?
