Update AppComponent Test

Run tests

We haven’t tested our app yet. For now, we only need to update the existing tests that Angular generated when we created our app.

Note: There are two types of application behaviors in this course.

• One will always have the ng test command set by default for testing.
• The other will have ng serve --port 8080 --host 0.0.0.0 --disable-host-check to run the server.

Throughout the course, if you wish to change the behavior, simply terminate the current execution using CTRL+C and start the desired process. Note that you need your API in running state (npm run api-test) before you serve your application.
