Any way mocking @Transactional()

[sunjoong85]

Problem

I got this message in my test codes No CLS namespace defined in your app ... please call initializeTransactionalContext() before application start.

Question

Are there any ways to mock @Transactional() in my test codes?

My test codes are below.

describe('Approval', () => {
    test('Approve booking.', async () => {
      /**
       * Given
       * orderId
       */
      const orderId = '1234';

      const spy_OrderRepository_findOrder = jest.spyOn(orderRepository, 'findOrder');
      const spy_OrderRepository_saveOrder = jest.spyOn(orderRepository, 'saveOrder');

      /**
       * When
       * Host confirms booking request.
       */
     //confirmRequest is wrapped by @Transactional()
      await hostOrderService.confirmRequest(orderId');

     /**
     * Then
     *  Success
     */

Furthermore, is it possible to manage transactions in a service layer without this hook? Currently, NestJS integration is not possible to control typeorm transaction features among services, not repositories.

Great job! Thanks!

Oops.

I think calling ' initializeTransactionalContext()' works fine.

I will close this issue.

describe('Reservation Management', () => {
  let hostOrderService: HostOrderService;
  let orderRepository: OrderRepository;

  beforeAll(async () => {
    initializeTransactionalContext();

    const module = await Test.createTestingModule({
      providers: [HostOrderService, OrderRepositoryMock, PaymentServiceMock],
    }).compile();

    hostOrderService = module.get<HostOrderService>(HostOrderService);
    orderRepository = module.get<OrderRepository>(OrderRepository);
  });

Sorry. It didn't work.

Without DB connection I got this error.

 ConnectionNotFoundError: Connection "default" was not found.

I got it! Mock Transactional decorator
