How do you test a component in Angular?

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

beforeEach(() => {
  TestBed.configureTestingModule({ declarations: [MyComponent] }).compileComponents();
});

it('should create', () => {
  const fixture = TestBed.createComponent(MyComponent);
  const component = fixture.componentInstance;
  expect(component).toBeTruthy();
});
