Question

我有一个必须期待的规范，它说没有期望...

 it('should click on yes button of technician and check save&continue 
  functionality', () => {
    const saveAndContinue = 
    fixture.debugElement.query(By.css(saveContinueBtn)).nativeElement;
    saveAndContinue.click();
    fixture.detectChanges();
    fixture.whenStable().then(() => {
    const spy = spyOn(component, 
    'isSaveAndContinueClicked').and.callThrough();
    expect(component).toBeDefined();
    expect(spy);
    component.isSaveAndContinueClicked();
    expect(component.isSaveAndContinueClicked).toHaveBeenCalled();
    const yesbutton = 
    fixture.debugElement.query(By.css('#yesButton')).nativeElement;
    expect(yesbutton).toBeTruthy();
    fixture.detectChanges();
    fixture.whenStable().then(() => {
    spyOn(component, 'change').and.callThrough();
    spyOn(component, 'change2').and.callThrough();
    yesbutton.click();
    expect(component.change).toHaveBeenCalled();
    expect(component.change2).toHaveBeenCalled();
    });
  });
});

它抛出错误，因为spec testComponent应该单击技术人员的“是”按钮，并检查“保存并继续”功能没有期望... 你能建议...

您应该在async或fakeAsync块中添加回调，否则所有代码将同步运行而不会遇到任何expects。

这是因为您在fixture.whenStable().then(() => {....})内部有断言，该断言是异步运行的。

it('should click on yes button of technician and check save&continue 
  functionality', async(() => {
    const saveAndContinue = 
    fixture.debugElement.query(By.css(saveContinueBtn)).nativeElement;
    saveAndContinue.click();
    ........

}));

规格没有期望值控制台错误，尽管存在期望值
