parametrize ignores marks if parameters are symbols

[TristenHayfield]

@pytest.mark.parameterize does not evaluate marks if parameters are symbols.
Here's an example:

import pytest


@pytest.mark.parametrize('v', [pytest.mark.alpha(0), pytest.mark.bravo(1)])
def test_bug(v):
    pass


def babby():
    pass

@pytest.mark.parametrize('v', [pytest.mark.alpha(babby), pytest.mark.bravo(babby)], ids=['alpha', 'bravo'])
def test_symbug(v):
    pass

$ pytest -v -s --collect-only -m alpha

Missing from the above is "<Function 'test_symbug[alpha]'>"

This reproduces in a clean virtual environment with python 2.7.9 and pytest 3.0.5 installed.

Is this a known issue?

marks applied to plain functions break apart, this is a known issue - the planned solution is #1921

[nicoddemus]

Should we close this? Feels like a duplicate of the known situation about markings/parametrize.

I lost track of the original issue

[TristenHayfield]

IMO duplicates can be kept open until the issue is resolved (although it depends on how well your bug-tracker can handle duplicates).

[RonnyPfannschmidt]

the github issue tracker is a bare minimum product ^^

#1921 fixed this - will be released on 3.1 or 4.1
