Using multiple pytest.mark.parametrize decorators

Multiple pytest.mark.parametrize decorators could be used in test functions to get the cartesian product of the parameters.

This snippet:

import itertools
import pytest
​
numbers = [1,2,3,4,5]
vowels = ['a','e','i','o','u']
​
@pytest.mark.parametrize(
    itertools.product(number, vowels)
)
def test(number, vowel):
    ...

is equivalent to this other snippet.

import pytest
​
numbers = [1,2,3,4,5]
vowels = ['a','e','i','o','u']
​
@pytest.mark.parametrize('number', numbers)
@pytest.mark.parametrize('vowel', vowels)
def test(number, vowel):
    pass
