Chapter learning outcomes

In this chapter, we are going to look at testing, which is an essential part of developing an enterprise-level application. We will briefly discuss the importance of writing tests and the benefits of following a Test-Driven Development (TDD) approach. We will then look at how Angular supports testing by reviewing the test spec files that Angular generates automatically through the CLI. Then, we’ll see how to run our tests to check if they have all passed or failed.
