Running Tests Using the Angular CLI

Command to run tests

To run the tests within an Angular application, we can simply use a single command to the Angular CLI:

ng test

This will begin the process of starting Karma, launching the browser, and finding and running all the test specs we have in our code base. Then, within the same Terminal window, we will see the outcome of the tests and if they have passed or failed.

📝 Note: Press the RUN button to run the ng test command. Once the test runs, click on the URL given after Your app can be found at, and see what happens!
