Quick Answer
Python unit testing: use unittest (built-in) or pytest (more popular). unittest: subclass TestCase, write test_* methods, use self.assertEqual/assertRaises/etc. pytest: just write functions starting with test_, use assert statements (pytest rewrites them for detailed failures). Fixtures, parametrize, and mocking with unittest.mock. Run with pytest or python -m unittest. Aim for 80%+ coverage.
