单元测试错误预期对标准“匹配URL：/ test-env / v1 / ezshopcart / locale / create / 1”的一个匹配请求，未找到

Question

我是这个角单元测试的新手，在测试上述标题的服务电话时遇到错误。 建议一些解决方案。

**Service:** 

  // Add locale in particular store
  addlocale(appLocale) {
    return this.getJwt(this.adminToken).pipe(//Called jwt api 
      switchMap(data => {
        this.authToken = data;
        this.authToken1 = this.authToken.data.JWT;
        let header = new HttpHeaders();
        header = header.append('Authorization', this.authToken1);
        header = header.append('Content-Type', 'application/json');
        return this.http.post(this.url + 'locale/create/1', appLocale, { headers: header });    //HTtp call with header
      }));
  }



**Test case for the above service:**

   it('Should post locale', () => {

  const dummyParam = 1;
  const locale: AppLocale[] = [
    {locale_id: 10,
    country: 'India',
    language: 'Kan_In',
    locale: 'Bng'
     } ];

     service.addlocale(locale).subscribe(response => {
      console.log('Will come plz');
      expect(response['data'].locale_id).toEqual('10');
      //expect(response['data'].language).toEqual('Kan_In');
    });

  const req1 = http.expectOne('/test-env/v1/ezshopcart/JWT');

  const req = http.expectOne('/test-env/v1/ezshopcart/locale/create/1');

  //expect(req.request.method).toEqual('POST') && req.request.headers.get('Content-Type') === 'application/json' && req.request.headers.get('Authorization') === 'eyJhbGciOiJIUzUxMiJ9.eyJzdWIiOiJhdXRoMCJ9.93ijRbI37Czi8CW28R1aPNemFV7Qpfu1fNxtt75jxZWHBJQo5ex1NasASTm0y0o5CPygXD1tDYVMqvOFtfeZrg';
  expect(req.request.method).toEqual('POST');
  expect(req.cancelled).toBeFalsy();
  expect(req.request.responseType).toEqual('json');


  req.flush(locale);
  req1.flush(locale);
  });

收到这样的错误消息预期对标准“匹配URL：/ test-env / v1 / ezshopcart / locale / create / 1”的一个匹配请求，未找到任何请求。
