尽管存在预期，但规范没有预期控制台错误

我有必须期待的规范，但它仍然说没有期望......

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();
        });
   });
});

它会抛出错误，因为规范测试组件应该单击技术人员的“是”按钮并检查“保存并继续”功能没有预期... 可以请您推荐一下吗...

您应该在async or fakeAsync阻止，否则所有代码都会同步运行而不会遇到任何问题expects.

这是因为你内部有断言fixture.whenStable().then(() => {....})它异步运行。

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();
    ........

}));
