Unit testing—which involves testing small, isolatable pieces of code—can help you catch and fix bugs before they crop up in your final product. And by adopting test-driven development (TDD) and writing unit tests before production code, you can take even greater responsibility for your project's quality. Curious about how to best approach unit testing in your own Python projects? This course shows you how. Join instructor Jasmine Omeke as she goes over TDD techniques for Python projects using the pytest testing framework and a Docker container.
