💡 Learn how to design great software in 7 steps: https://arjan.codes/designguide.
Test-driven development (TDD), also known as red-green-refactor is a common software development technique in which you write tests before you write the actual code. In this video, I show an example in Python of how to do TDD using the unittest package. I also share a few practical tips related to software testing in this video.
