Question

我具有此登录功能，我想对其进行测试。但是我收到一个错误“异步回调未在5000毫秒内调用”

public async Login(email: string, password: string): Promise<any> {
    const body = { email, password };
    await this.getCSRFToken().toPromise();
    return this.http
      .post<any>(this.baseUrl + 'login', body)
      .pipe(
        tap(data => {
          this.user = data;
          return this.user;
        })
      )
      .toPromise();
  }

我的测试：

it('should login', (done) => {
    const service: AuthenticationService = TestBed.get(AuthenticationService);
    const http = TestBed.get(HttpTestingController);
    let userResponse;

    service.Login('email', 'password').then((response) => {
      userResponse = response;
    });

    http.expectOne((req) => {
      return req.method === 'POST'
        && req.url === '/frontend/login';
    }).flush({user_type: 'Test'});
    expect(userResponse).toEqual({user_type: 'Test'});

  });

任何想法??

可能有两个原因：

您忘了在最后添加done()函数。

it('should login', (done) => {
  const service: AuthenticationService = TestBed.get(AuthenticationService);
  const http = TestBed.get(HttpTestingController);
  let userResponse;

  service.Login('email', 'password').then((response) => {
    userResponse = response;
  });

  http.expectOne((req) => {
    return req.method === 'POST'
    && req.url === '/frontend/login';
  }).flush({user_type: 'Test'});
  expect(userResponse).toEqual({user_type: 'Test'});
  done(); // missed done function 
});

您需要增加默认超时时间jasmine.DEFAULT_TIMEOUT_INTERVAL。 `

可以在任何给定描述之外全局设置。
```
jasmine.DEFAULT_TIMEOUT_INTERVAL = 10000;
```
