The command is used to run the unit tests that are defined in the project. You can run the test by the ng test and ng t commands. You should call it per project but as long as you’re in the project directory you can skip that.

What are the tests? That’s not so obvious when there are multiple files related to tests across the project. But if you use the search to look for tests using their response message you’ll be able to spot them easily.
Voila!
