--looponfail consider junitxml output a change

[Daenyth]

Running pytest --looponfail --junitxml=report.xml tests/ results in the following:

• Runs the tests
• Generates the test report file
• File watcher says # MODIFIED path/to/report.xml
• Runs the tests
• Generates a new test report file...

I can invoke it without the report, that's fine, but it's annoying because I have the report argument in my tox.ini, so using tox -- --looponfail shows this behavior.

Given that the junitxml argument knows the file path, it seems like a potential solution here is to explicitly skip changes to that file.

It's likely there's a similar issue for html reports and coverage.

I'm still seeing this on the most recent pytest-xdist - 4 years later... 😕

--looponfail would require a new option to ignore some glob files to solve this I think.

A workaround is to use looponfailroots in your inifile to only watch the directories with your source code, instead of the current working directory.

The same issue occurs when pytest-cov or coverage is used to generate an HTML coverage report.
I think the best fix would indeed be a command line parameter to ignore a glob of files.
