茉莉花角测试：无法读取未定义的属性“订阅”

Question

运行测试时，出现以下错误： TypeError：无法读取未定义的属性“ subscribe”

我正在将服务注入规范并尝试订阅服务调用

规格：

     it('should fetch my client stats', inject(
      [ProfileService], (service: ProfileService) => {

        const spyC = spyOn(component, 'loadNewAgencyDashboard');
        const spyS = spyOn(service, 'fetchMyClientStats');

        service.currentProfile.next(mockProfile);
        service.fetchMyClientStats().subscribe((response: any) => {
          if (service.currentProfile.getValue().role.includes('AGENCY_VIEW')) {
            component.agencyView = true;
            component.loadNewAgencyDashboard();
          } else {
            component.loadNewAgencyDashboard();
          }
        });
        fixture.detectChanges();
        expect(spyS).toHaveBeenCalledTimes(1);
        //expect(component.agencyView).toEqual(true);
        //expect(spyC).toHaveBeenCalledTimes(1);
      }));

ts：

loadDashboard() {
    this.loadingDashboard = true;
    this.myName = this.profileService.currentProfile.getValue().fullname;
    this.profileService.fetchMyClientStats().subscribe((response: any) => {
      // this.AgentData = response.response;
      if (this.profileService.currentProfile.getValue().role.includes('AGENCY_VIEW')) {
        this.agencyView = true;
        this.loadNewAgencyDashboard();
      } else {
        this.loadNewAgentDashboard();
      }

    });
  }
