Pytest no longer supports gen_tests

[naught101]

Following the Readme, I get this:

  tests/test_helloworld.py:23: PytestWarning: yield tests were removed in pytest 4.0 - test_helloworld will be ignored
    @pytest.mark.gen_test

Any idea what I can do to replace it? All I need to test is a single call to a tornado websocket API.

Relevant docs: https://docs.pytest.org/en/latest/deprecations.html#yield-tests

I think it would work to still use the decorator but make the test function async (async def test_helloworld…) and replace the inner yield with await.

@naught101 I tried the example from the readme and do net get such a message.

Could you show your code and what versions of pytest-tornado and pytest you are using?

[naught101]

Sorry for the delay. I get this error when I clone this repo, and run pytest in it.

I get this error when I clone this repo, and run pytest in it.

It looks like you didn't install the package from the cloned repository?

[vidartf]

Typically you would install it with pip install -e . if you plan to work on the code.

[naught101]

I get the same errors if I install that way.

Strange. When installed correctly, it should show up in the "plugins" list printed by pytest at the start of the run (e.g. form latest CI: plugins: tornado-0.8.1). In your output it says plugins: profiling-1.7.0, tornasync-0.6.0.post2, cov-2.6.1, repeat-0.8.0.

Maybe there is an issue with you environment? Some tips to debug could be to run which pytest and which pip, and ensure they are all working towards the same Python environment. You could try creating a new environment as well?

I found this strange aswell. One thing that did stick out in @naught101 s pytest env info is pytest-tornasync. Once I install this the tests break for me aswell.
