In order to keep your unit tests running, you will need to import MaterialModule to any component's spec file that uses Angular material:
*.component.spec.ts... beforeEach( async(() => { TestBed.configureTestingModule({ ... imports: [..., MaterialModule, NoopAnimationsModule], }).compileComponents() }) )
You will also need to update any test, including e2e tests, that search for a particular HTML element.
For example, since the app's title, LocalCast Weather, is not in an h1 tag anymore, you must update the spec file to look for it in a span element:
src/app/app.component.spec.tsexpect(compiled.querySelector('span').textContent).toContain('LocalCast Weather')
Similarly, in e2e tests, you will need to update your page object ...
