Double Parameterization

So I have a set of tests where I'd like to test multiple versions of a solution. Currently I have import pytest import product_not_at_index functions_to_test = [ product_no

Solution 1:

The solution I ended up using is this one

import pytest

import product_not_at_index


functions_to_test = [product_not_at_index.product_not_at_index_n_squared]
test_data = [
    ([], []),
    ([1], [1]),
    ([1, 1], [1, 1]),
    ([1, 7, 3, 4],  [84, 12, 28, 21]),
]

# TODO: turn into a list comprehension.
test_paramaters = []
for func in functions_to_test:
    for test_input, expected_result in test_data:
        test_paramaters.append([test_input, expected_result, func])

@pytest.mark.parametrize("function_input,expected_result,test_func", test_paramaters)
def test_run(function_input, expected_result, test_func):
    actual_result = test_func(function_input)
    assert actual_result == expected_result
