Unit Tests for Angular 2 Applications
summary
Angular 2 unit testing focuses on concrete tools and recipes: use the testing module and TestBed.compileComponents to precompile templates, choose between real async (zones and fixture.whenStable) or fakeAsync/tick for controlled timing, get fixtures and call detectChanges to update the DOM, query with DebugElement or nativeElement, replace HTTP with MockBackend to control responses, and use RouterTestingModule or shallow stub components to keep tests isolated and fast.
