Combining multiple @pytest.mark.parametrize lines #815
Description
I sometimes write tests something like this:
@pytest.mark.parametrize('foo, bar', itertools.product(['a', 'b', 'c'], [1, 2, 3]))
def test_things(foo, bar):
...to test all combinations of foo and bar. The itertools.product call sometimes gets a bit more complicated which makes this hard to follow.
IMHO, it'd be nicer to be able to write those tests like this:
@pytest.mark.parametrize('foo', ['a', 'b'. 'c'])
@pytest.mark.parametrize('bar', [1, 2, 3])
def test_things(foo, bar):
...And pytest would then generate all possible combinations. What are your thoughts on this?
I'm not sure if the difference between using two args in one parametrize call vs. using two parametrize calls with one argument each is too subtle, though.
