Testing Angular components - Advanced

In this section, we will delve more deeply and learn some more important and advanced aspects of testing Angular components.

If you observe, you can note the following in the example mentioned in the preceding section:

1. We create an instance of the object individually each time in each test case.
2. We have to inject all the providers individually for each test case.

Instead, it will be great if we can define an instance of the component before each test script. We can achieve this by using TestBed--one of the most important utilities provided by Angular for testing.
