In this video we cover unit testing from beginner to intermediate (and even touch on some advanced topics). We have a lot of practical examples of testing different types of code. We also cover many fundamental assertions, different ways to write your tests and how to maintain your tests. Finally, we examine how the source code you write can make tests easier or harder to write.
This video is language agnostic. We use JavaScript for the examples, but the examples are easy to understand and translate into your own programming language. The concepts are universal and apply for all programming languages.
