What is Angular unit testing and how do I get started?

Angular unit testing involves testing individual components or services in isolation to ensure they work as intended. You can get started by using tools like Jasmine and Karma.

What tools do I need for Angular unit testing?

You'll need Jasmine for writing tests and Karma as a test runner. Angular CLI also provides built-in support for these tools.

Can you give me an example of a simple unit test in Angular?

Sure! Here's a simple test for a component:

import { ComponentFixture, TestBed } from '@angular/core/testing';
import { MyComponent } from './my.component';

describe('MyComponent', () => {
  let component: MyComponent;
  let fixture: ComponentFixture<MyComponent>;

  beforeEach(() => {
    TestBed.configureTestingModule({
      declarations: [MyComponent]
    });
    fixture = TestBed.createComponent(MyComponent);
    component = fixture.componentInstance;
  });

  it('should create', () => {
    expect(component).toBeTruthy();
  });
});

How do I run my unit tests?

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