Experimental Class Class Overview class Title { getTitle() : string setTitle(newTitle: string) } Class Description A service that can be used to get and set the title of a current HTML document. Since an Angular 2 application can't be bootstrapped on the entire HTML document (<html> tag) it is not possible to bind to the text property of the HTMLTitleElement elements (representing the <title> tag). Instead, this service can be used to set and get the current title value.

Experimental Function Class Export export tick(millis?: number) : void Simulates the asynchronous passage of time for the timers in the fakeAsync zone. The microtasks queue is drained at the very start of this function and after any timer callback has been executed. Example describe('this test', () => { it('looks async but is synchronous', <any>fakeAsync((): void => { var flag = false; setTimeout(() => { flag = true; }, 100); expect(flag).toBe(false);
