Parameterized tests for Python's unittest module

Project description

Parameterized tests for Python’s unittest module

This was inspired by the parameterized tests feature in py.test. I had been using py.test for the particular test that motivated this, but my colleague had some reservations about using py.test and all I really needed was the parameterized tests so I whipped this up with a bit of metaclass hackery.

Example usage

from parameterizedtestcase import ParameterizedTestCase

class MyTests(ParameterizedTestCase):
        ("input", "expected_output"),
            ("2+4", 6),
            ("3+5", 8),
            ("6*9", 54),
    def test_eval(self, input, expected_output):
        self.assertEqual(eval(input), expected_output)

Result of running this:

~/dev/git-repos/python_unittest_parameterized_test_case$ python -m unittest -v tests
test_eval_input_2+4_expected_output_6 (tests.MyTests) ... ok
test_eval_input_3+5_expected_output_8 (tests.MyTests) ... ok
test_eval_input_6*9_expected_output_54 (tests.MyTests) ... ok
