Question

 describe('BannerComponent (inline template)', () => {

    let comp:    LoginComponent;
    let fixture: ComponentFixture<LoginComponent>;
    let de:      DebugElement;
    let el:      HTMLElement;

    it('should display original title', () => {
      fixture.detectChanges();
      expect(el.textContent).toContain(comp.signIn);
    });

    it('should display a different test title', () => {
      comp.signIn = 'Test Title';
      fixture.detectChanges();
      expect(el.textContent).toContain('Test Title');
    });

    beforeEach(() => {
      TestBed.configureTestingModule({
        declarations: [ LoginComponent ], // declare the test component
      });

      fixture = TestBed.createComponent(LoginComponent);

      comp = fixture.componentInstance; // BannerComponent test instance

      // query for the title <h1> by CSS element selector
      de = fixture.debugElement.query(By.css('./login.component.scss'));
      el = de.nativeElement;
    });

以上是我写的代码，但我面临的错误如

类型的参数＆＃39;（userName：any，password：any）=＆gt;空隙＆＃39;不能分配给＆＃39;预期＆＃39;类型的参数。输入＆＃39;（userName：any，密码：any）=＆gt;空隙＆＃39;不能分配给＆＃39; ObjectContaining＆＃39;。物业＆＃39; jasmineMatches＆＃39;类型＆＃39;中缺少（userName：any，密码：any）=＆gt;空隙＆＃39;
