parameterized. I love the @parametrize decorator in pytest, which lets you run the same test multiple times against multiple parameters. The only catch is that the decorator in pytest doesn’t work for old-style unittest TestCase tests, which means you can’t easily add it to test suites that were built using the older model. I just found out about parameterized which works with unittest tests whether or not you are running them using the pytest test runner.
