PytestUnknownMarkWarning: Unknown pytest.mark.datafiles with pytest 6.2.4

[KirkDCO]

I see a similar issue with an earlier version of pytest (4.3.0) which appears to have been fixed with pytest v4.5.0. But I'm using pytest v6.2.4 - is there something I'm missing?

Hi, same here

Have you tried registering the marker in your config file? Check out hf-krechan's Feb. 10 answer on the 4.3.0 issue thread. Worked for me.

Doubt.

Right you are @travipross and sorry about that! Too many things and I haven't needed the plugin myself in years, so yeah... I want to have a look at all the pull requests and issues in the next weeks. To be honest I can't believe that so many people appear to be using the plugin. I will try to do better!

[travipross]

@omarkohl haha don't take my comment too seriously at all. I was just being cheeky. Thank you for contributing to the open source world! This is a solid plugin.

[omarkohl]

Should be fixed in commit f95315e . I will make a release soon.

Released in 2.0.1
