How to choose the right test types for Node and JavaScript, code them correctly, measure their effectiveness and host them in a CI/CD pipeline in the right way 💪🏼

But today i’m here to hopefully take some of that pressure off of your shoulders and hopefully walk you through some examples that you can begin to implement in the code base your working on right now!

​​I recently decided to improve unit test performance on a newly joined project. It felt like it takes too long to test the whole suite (32 tests only) as well as test a separate file in isolation with watch mode. The direct consequences of that are that developers are not enjoying the process and trying to avoid touching unit tests. Product quality suffers in the long run.
