Tests directory name gets autocompleted

[jdelafon]

My project has a directory tests containing the unit tests I want to run with pytests. It also has a directory tests_functional, which I don't want to run continuously.

py.test tests/

will run only my unit tests, while

ptw tests/

will also run everything in tests_functional, even so:

ptw --ignore ./tests_functional ./tests

I don't see any way to run only what is in the tests folder. Moreover, I would expect a pytest extension to gather tests the same way pytest (and pytest-xdist) does.

Hi, @muraveill!

At a glance, this looks like a bug. I'll take a deeper look at this later to see what's going on.

For now, try passing those args directly to py.test:

$ ptw -- --ignore ./tests_functional

(Note the extra --. Also the ./tests argument shouldn't be necessary.)

Ok, so it turns out this worked as implemented. But since the CLI is misleading about what --ignore does, and that running ptw --ignore tests_functional -- --ignore tests_functional is way too verbose, I'm looking into improving this.

In the next release, you should be able to do what you did an expect it to ignore tests_functional in both the pytest-watch observer and in py.test.

Thanks for pointing out this awkward design!

Just published v4.0, which forwards all --ignore arguments to pytest (6f3eb56).

After running pip install --upgrade pytest-watch, you should be able to run

$ ptw --ignore ./tests_functional

and have it work as expected (ptw doesn't watch that directory and pytest doesn't collect tests from it either). Thanks again!

It works perfectly now, thanks!
