Question

我正在测试服务getTokenRequest是否失败。然后我要测试这两行MyExtensions

在测试this.ngLoggerDispatcher(JSON.stringify(error)); return throwError('get token request');中，我监视了getTokenRequest should throw an error，并抛出了一个错误httpService.getAccessToken 然后，我致电get token request，然后检查是否已致电utilsService.getTokenRequest。

该测试运行成功，但是测试utilsService.ngLoggerDispatcher失败，并显示错误getFile，我不明白为什么。

在浏览器控制台中，我出现错误object ErrorEvent thrown

utils.service.spec.ts

Uncaught get token request

utils.service.ts

it('getTokenRequest should throw an error', inject([UtilsService, HttpService],
    (utilsService: UtilsService, httpService: HttpService) => {

      spyOn(httpService, 'getAccessToken').and.returnValue(throwError('get token request'));
      utilsService.getTokenRequest('test.pdf', 'hashcode').pipe(
        tap(() => expect(spyOn(utilsService, 'ngLoggerDispatcher')).toHaveBeenCalled())
      ).subscribe();

    }));



it('getFile', inject([UtilsService, HttpService],
    (utilsService: UtilsService, httpService: HttpService) => {

      store.dispatch(new SetUrlDownload('urlDownloadTest'));
      utilsService.getFile().pipe(
        tap(() => expect(spyOn(httpService, 'getFile')).toHaveBeenCalledWith('urlDownloadTest'))
      ).subscribe();

    }));

http.service.ts

getTokenRequest(fileName: string, hashcode: string): Observable<TokenRequestResponse> {

    return this.httpService.getAccessToken()
      .pipe(
        mergeMap((accessToken: string) =>
          this.httpService.getTokenRequest(fileName, hashcode, accessToken)
        ),
        catchError((error: Error) => {
          this.ngLoggerDispatcher(JSON.stringify(error));
          return throwError('get file');
        })
      );
  }

编辑：执行命令getAccessToken(): Observable<string> { return from(this.tokenService.token).pipe( map(({ accessToken }) => accessToken) ); } getTokenRequest(fileName: string, hashcode: string, accessToken: string): Observable<TokenRequestResponse> { return this.httpClient.post<TokenRequestResponse>('...'); } } 我收到错误ng test --source-map=false，但不知道有什么帮助 error screenshot

引发对象ErrorEvent
