错误：超时 - 未在 30000 毫秒内调用异步回调（由 jasmine.DEFAULT_TIMEOUT_INTERVAL 设置）答案

【问题标题】：Error: Timeout - Async callback was not invoked within 30000ms (set by jasmine.DEFAULT_TIMEOUT_INTERVAL)错误：超时 - 未在 30000 毫秒内调用异步回调（由 jasmine.DEFAULT_TIMEOUT_INTERVAL 设置）

【问题描述】：

无论我做什么，仍然无法使测试正常运行。尽管通过所有其他帖子我尝试了所有可能的解决方案，但仍然无法正常工作。设置jasmine.DEFAULT_TIMEOUT_INTERVAL = 30000;我认为它会起作用，但没有成功。任何想法如何解决这个问题？

describe('DashboardComponent', () => {
  let component: DashboardComponent;
  let fixture: ComponentFixture<DashboardComponent>;
  let therapistStatus = TherapistStatus;

  let id = '';
  let firstName = '';
  let lastName = '';
  let email = '';
  let status = 2;
  let statusChanges = '';
  let therapist = new Therapist({id, firstName, lastName, email, status, statusChanges});


  beforeEach(async(() => {
    jasmine.DEFAULT_TIMEOUT_INTERVAL = 30000;
    TestBed.configureTestingModule({
      declarations: [ DashboardComponent],
      schemas: [NO_ERRORS_SCHEMA],
      imports: [
        RouterTestingModule,
        FormsModule,
        OAuthModule.forRoot(),
        ToastrModule.forRoot(),
        HttpClientTestingModule,
        ReactiveFormsModule,
        TranslateModule.forRoot()

      ],
      providers: [UserService]
    })
      .compileComponents().then(() => {
      fixture = TestBed.createComponent(DashboardComponent);
      component = fixture.componentInstance;
    });
  }));

  beforeEach(() => {
    fixture = TestBed.createComponent(DashboardComponent);
    component = fixture.componentInstance;
    fixture.detectChanges();
  });

  it('should create the dashboard component', () => {
    expect(component).toBeTruthy();

  });

【解决方案1】：

您不需要使模块实例化异步。尝试删除并修改您的代码如下（请检查括号是否遗漏）。希望这会有所帮助。

describe('DashboardComponent', () => {
  let component: DashboardComponent;
  let fixture: ComponentFixture<DashboardComponent>;
  let therapistStatus = TherapistStatus;

  let id = '';
  let firstName = '';
  let lastName = '';
  let email = '';
  let status = 2;
  let statusChanges = '';
  let therapist = new Therapist({id, firstName, lastName, email, status, statusChanges});


  beforeEach(() => {
    jasmine.DEFAULT_TIMEOUT_INTERVAL = 30000;
    TestBed.configureTestingModule({
      declarations: [ DashboardComponent],
      schemas: [NO_ERRORS_SCHEMA],
      imports: [
        RouterTestingModule,
        FormsModule,
        OAuthModule.forRoot(),
        ToastrModule.forRoot(),
        HttpClientTestingModule,
        ReactiveFormsModule,
        TranslateModule.forRoot()

      ],
      providers: [UserService]
    }).compileComponents();
  fixture = TestBed.createComponent(DashboardComponent);
  component = fixture.componentInstance;
  });

  beforeEach(() => {
    fixture = TestBed.createComponent(DashboardComponent);
    component = fixture.componentInstance;
    fixture.detectChanges();
  });

  it('should create the dashboard component', () => {
    expect(component).toBeTruthy();

  });
