How do I set up Jasmine for testing in my Angular project?

To set up Jasmine in your Angular project, you need to ensure that Jasmine is included in your testing framework. If you're using Angular CLI, Jasmine is already included by default. You can start by creating a spec file for your component.

What is a spec file?

A spec file is a JavaScript file that contains your test cases. It typically has the same name as the component you're testing, with a .spec.ts extension. For example, if your component is app.component.ts, the spec file would be app.component.spec.ts.

How do I write a simple test case in the spec file?

You can write a simple test case using the it function. For example: it('should create the component', () => { const fixture = TestBed.createComponent(AppComponent); const app = fixture.componentInstance; expect(app).toBeTruthy(); }); This checks if the component is created successfully.

How do I run the tests?

You can run your tests using the Angular CLI command ng test. This will start the Karma test runner and execute your Jasmine tests.
