Hi,

using pytest 3.0.5 (and xdist (1.15) + cov plugins (2.3.1)), under linux :

reproduce steps :

18:58 $ cat test_pytest_pdb_skip.py

import platform

import unittest2 as unittest


@unittest.skipIf(platform.system() != 'Windows', 'This test need to be run on Windows!')
class MyTestCase(unittest.TestCase):

    def test_one(self):
        self.assertTrue(False)

this is ok :
pytest -xv test_pytest_pdb_skip.py

this is not ok : the test is executed and here obviously fail
pytest --pdb -xv test_pytest_pdb_skip.py

Thanks for the report!

This is a side effect of #1890, because now the skip machinery for unittest.TestCase tests is not reached when --pdb is given in the command line (unittest.py:155):

    def runtest(self):
        if self.config.pluginmanager.get_plugin("pdbinvoke") is None:
            self._testcase(result=self)
        else:
            # disables tearDown and cleanups for post mortem debugging (see #1890)
            self._testcase.debug()

Have to think about a proper fix for this, we probably need to handle other types of failures as well (such as unexpectedSuccess). Perhaps @mbyt can chime in?

Thanks for reporting - and yes, that's definitely a regression.

@nicoddemus, sorry for being late. I looked into this and proposed a possible solution in #2225.
