Improved Jest debugging experience in Angular

Improved Jest debugging experience in Angular

Jest is user-friendly, has a great command-line interface, and most importantly it's fast. Jest is fast because doesn't have to spin up a browser but instead runs its tests against a virtual DOM. The virtual DOM has many advantages but it also makes debugging Angular components harder. In this video, I am going to show you a nice tip on how to improve your debugging experience with Jest while writing Angular component tests.
