Markers and fixtures

There are some builtin markers and fixtures in pytest-cov.

Markers

no_cover

Eg:

@pytest.mark.no_cover
def test_foobar():
    # do some stuff that needs coverage disabled

Warning

Caveat

Note that subprocess coverage will also be disabled.

Fixtures

no_cover

Eg:

def test_foobar(no_cover):
    # same as the marker ...

cov

For reasons that no one can remember there is a cov fixture that provides access to the underlying Coverage instance. Some say this is a disguised foot-gun and should be removed, and some think mysteries make life more interesting and it should be left alone.
