Cannot select test by mark using lower case param

[ay0o]

import pytest

@pytest.mark.parametrize('kind', [
    pytest.param('integration', marks=[pytest.mark.integration]),
    pytest.param('stability', marks=[pytest.mark.stability]),
])
def test_foo(kind):
    assert kind == 'integration'

If I run for example pytest -m integration, it won't select any test. However, if I edit the param and make it uppercase, it works fine. So, above code doesn't work, but the below works:

import pytest

@pytest.mark.parametrize('kind', [
    pytest.param('INTEGRATION', marks=[pytest.mark.integration]),
    pytest.param('STABILITY', marks=[pytest.mark.stability]),
])
def test_foo(kind):
    assert kind == 'INTEGRATION'

I can successfully run pytest -m integration and only integration will be used. Likewise, pytest -m stability selects only stability.

I don't see any constraints about upper case characters in the documentation, in fact, the examples use params in lower case, so I suppose this is a bug.

Software:
Python 3.6.4
pytest 3.5.1

@ay0o this is possibly one of the mark issues, can you please verify if it happens on the features branch as well (there we changed some things to be more correct)

[pytestbot]

GitMate.io thinks possibly related issues are #552 (Can't mark.xfail a callable test param), #50 (Select tests according to their mark), #3100 (Cannot dynamically mark a test as xfail), #2355 (using pytest.mark.skipIf doesn't skip anything, but calling pytest.mark.skipif (all lower case) works), and #3368 (Applying multiple skipifs to parametrized test using param(marks=[]) is order dependent).

Hi @RonnyPfannschmidt, how can I use the version in the features branch? Is there any package I can just pip install?

[RonnyPfannschmidt]

you can pip install the feature branch either from a git checkout, or via a pip scm url that clones the repo

[ay0o]

ok, confirmed it's fixed in the branch "features".

Is there any expected release date?

[RonnyPfannschmidt]

@ay0o we aim to release this week, thanks for verifying
