Unit Testing for Unity 101: Theory (Full Lecture with Q&A)

Stop! You have committed crimes against programming. In this lecture, we will give you an introduction to the topic of Unit Testing, why it’s necessary for writing good code, and how to do it. School curriculums usually don’t cover this, especially in Game Design, but Unity codebases can get so huge that even small projects become unmanageable without proper tests in place. Vasil and Anne from Den of Thieves Games will cover why Unit Testing is essential and will show you how to get started with it in Unity.
