Let's recap

In this chapter we looked at four ways to test Angular components: isolated tests, shallow tests, integration tests, and protractor tests. Each of them have their time and place: isolated tests are a great way to test drive your components and test complex logic. Shallow tests are isolated tests on steroids, and they should be used when writing a meaningful test requires to render a component’s template. Finally, integration and protractor tests verify that a group of components and services (i.e., the application) work together.
