示例1: dispatchEvent
tcb.createAsync(DemoFormWithEvents).then((fixture) => {
let el = fixture.debugElement.nativeElement;
let input = fixture.debugElement.query(By.css("input")).nativeElement;
let form = fixture.debugElement.query(By.css("form")).nativeElement;
fixture.detectChanges();
input.value = '';
dispatchEvent(input, 'input');
fixture.detectChanges();
tick();
// no value on sku field, all error messages are displayed
