How do I set up testing in Angular CLI?

To set up testing in Angular CLI, you can use the built-in testing framework, Jasmine, along with Karma as the test runner. First, ensure you have Angular CLI installed, then create a new Angular project using ng new my-app. This will automatically set up testing for you.

What files are created for testing?

When you create a new Angular project, you'll find a src/app/app.component.spec.ts file, which is a test file for the AppComponent. Additionally, the karma.conf.js file is created for configuring the Karma test runner.

How do I run the tests?

You can run the tests by executing the command ng test in your terminal. This will start the Karma test runner and execute all the tests in your project.

Can I add more tests for my components?

Yes, you can add more tests by creating additional .spec.ts files for your components or by adding more test cases within the existing spec files.
