示例1: it
it('should pass a blog item to remove to the blogService during delete', () => {
blogRoll.ngOnInit();
// alerts/confirm are an awful idea (short timeframe for this demo)
// but we can deal with the confirm message box by mocking it away,
// and returning true to continue processing - thanks Jasmine!
spyOn(window, 'confirm')
.and.callFake(() => { return true; });
// now mock the actual call to
spyOn(blogService, 'deleteBlogEntry')
.and.returnValue(Observable.of({ complete: true}));
