Pytest: Deselecting tests

Question

With pytest, one can mark tests using a decorator

@pytest.mark.slow
def some_slow_test():
    pass

Then, from the command line, one can tell py

Answer 1

Additionally, with the recent addition of the "-m" command line option you should be able to write:

py.test -m "not (slow or long)"

IOW, the "-m" option accepts an expression which can make use of markers as boolean values (if a marker does not exist on a test function it's value is False, if it exists, it is True).
