Integration with pytest-watch

[brunolnetto]

Summary

I am able to run pytest in watch mode using package pytest-watch. However, when I want to see the code coverage with pytest-cov, I have to run command below. Can you provide a watch mode for pytest-cov as well

coverage run -m pytest
coverage report -m

You might like entr (http://eradman.com/entrproject/) which runs arbitrary commands when files change. Is there a reason this has to be tightly integrated with pytest?

[brunolnetto]

Well, for the same reason pytest-watch is a great dev tool.

Can you explain why? What does it do that works better than entr?

[brunolnetto]

Sure. The arguments are twofolded:

1. Usability: instead of memorizing an additional command, entr, having a tag like '--watch' i.e. '-w' would make the experience valuable;
2. Compliance: complies to pytest-watch interface, which is a familiar tool already.
