Close but what I think we want here is a conditional xfail. This tests passes when run against production (mozillians.org) but fails when run against dev and stage. We want this https://github.com/mozilla/mozillians-tests/pull/120/files#diff-4f911ad9b2aff71ce2163e7146e59c7fR70

@pytest.mark.xfail("'allizom' in config.getvalue('base_url')",  reason="bug 960302 - <bug summary>””)
