pytest.mark on TestCase affects base classes

[qwiglydee]

When pytest.mark.skipif applied to a class with bases (mixins) the tests from base clases are disabled for all other testcases.

platform linux -- Python 3.4.3, pytest-2.9.0, py-1.4.30, pluggy-0.3.1

from unittest import TestCase
import pytest


class BaseMixin():
    def test_foo(self):
        True


@pytest.mark.skipif(True, reason="disabled")
class TestBar(BaseMixin, TestCase):
    def test_bar(self):
        True


class TestBaz(BaseMixin, TestCase):
    def test_baz(self):
        True

output:

collected 4 items 

tests.py::TestBar::test_bar SKIPPED
tests.py::TestBar::test_foo SKIPPED
tests.py::TestBaz::test_baz PASSED
tests.py::TestBaz::test_foo SKIPPED
=============================== 1 passed, 3 skipped in 0.04 seconds

The tests.py::TestBaz::test_foo was skipped because of mark at TestBar

Yep, it's a known issue... fixing it unfortunately is not so simple. 😬

See #631, #725, #568.
