The parametrization order appears to be random when @pytest_fixture_plus is used with several @pytest.mark.parametrize

[smarie]

Consider the following example:

A = [1, 2]
B = [10, 20]

@pytest_fixture_plus
@pytest.mark.parametrize("a", A)
@pytest.mark.parametrize("b", B)
def my_fix(a, b):
    return a + b

def test_my_fix(my_fix):
    pass

The order of execution will randomly be 1-10, 1-20, 2-10, 2-20 or 10-1, 10-2, 20-1, 20-2.

This was a stupid error in the code: a dict was used instead of an OrderedDict
