我是Jest的新手，遇到了在多个it（）块中模拟httpService的问题。在第一个it（）块中模拟httpService之后，第二个it（）块无法通过。我尝试过使用spyOn，但它与AxiosResponse的效果并不好，即使修复了它，第二个块仍然失败。我还尝试了clearAllMocks（）和resetAllMocks（），但它们没有解决这个问题。有人可以帮助我理解和解决这个问题吗？

beforeEach(async () => {
    module = await Test.createTestingModule({
      providers: [CPDCService, ...providersMock]
    }).compile();

    service = module.get<CPDCService>(CPDCService);
    jest.resetAllMocks();
  });

  it('should be defined', () => {
    expect(service).toBeDefined();
  });

  describe('submit', () => {
    it('should throw BadRequestException when Recaptcha token is invalid', async () => {
      const httpService = module.get<HttpService>(HttpService);
      const cpdcData: CPDCDto = {
        formData: {
          recaptchaToken: 'mockRecaptchaToken',
          email: 'test@example.com'
        },
        campaignId: 'mockCampaignId',
        bountyId: 'mockBountyId',
        formId: 'mockFormId',
        referrer: 'google.com',
        deviceId: 'mockDeviceId'
      };

      // Mock the response from the recaptcha verification
      const recaptchaResponse = {
        data: {
          success: false
        }
      };
      // Create a spy on the `post` method of `httpService`
      const mockObservable = {
        toPromise: () => Promise.resolve(recaptchaResponse)
      };
      httpService.post = jest.fn().mockImplementation(() => mockObservable);

      await expect(service.submit(cpdcData, true, undefined, 'en')).rejects.toThrow(
        BadRequestException
      );
    });
    it('should throw NotFoundException when campaign is not found', async () => {
      const httpService = module.get<HttpService>(HttpService);
      const cpdcData: CPDCDto = {
        formData: {
          recaptchaToken: 'mockRecaptchaToken',
          email: 'test@example.com'
        },
        campaignId: 'mockCampaignId',
        bountyId: 'mockBountyId',
        formId: 'mockFormId',
        referrer: 'google.com',
        deviceId: 'mockDeviceId'
      };

      // Mock the response from the recaptcha verification
      const recaptchaResponse = {
        data: {
          success: true
        }
      };
      // Create a spy on the `post` method of `httpService`
      const mockObservable = {
        toPromise: () => Promise.resolve(recaptchaResponse)
      };
      httpService.post = jest.fn().mockImplementation(() => mockObservable);

      await expect(service.submit(cpdcData, true, undefined, 'en')).rejects.toThrow(
        NotFoundException
      );
    });
  });
});
