Unit testing is a key tool for ensuring the correctness of our software, and Angular apps are no exception! In fact, part of what makes Angular so amazing is that it's a framework written from the ground up with testing in mind. Filters in Angular are often smaller and simpler than other Angular constructs like controllers or directives, but just like these other parts that make up an Angular application, filters can and should be unit tested to ensure they work as intended.
In this Coffee Break Course, Envato Tuts+ instructor Dan Wellman will show you how to take an existing Angular app and add tests for one of its filters. You'll see how to write unit tests with Jasmine and then use Karma to run the tests from the command line.
