[pytest-dev] excluding marked tests as default behavior

[Ofer Nave]

I do have a working implementation with the following:

1) Create a marker:

slow = pytest.mark.skipif("'SLOW' not in os.environ")

2) Mark appropriate tests:

@slow
def test_which_is_slow():
     ...

3) Turn on slow tests from command line:

$ SLOW=1 py.test

Not exactly the form factor I was looking for, but it does work.
