nestjsx-automapper profiles not found in nestjs test modules

EDIT: This is an old question that I made in my earlies. Looking at the docs would have solved this instantly (so this should not be relevant for anyone).

Im trying to make unit testing for some features in my NestJS API.

I make use of nestjsx-automapper. The exception happens only while testing any service that uses mappings. I use @nestjs/testing and jest. I have managed to replicate the error in this test:

describe('UserController', () => {
  let userServiceInterface: UserServiceInterface;

  beforeEach(async () => {
    const app: TestingModule = await Test.createTestingModule({
      imports: [AutomapperModule.withMapper('user')],
      providers: [
        {
          provide: 'UserServiceInterface',
          useClass: UserService,
        },
      ],
    }).compile();

    userServiceInterface = app.get<UserServiceInterface>(
      'UserServiceInterface',
    );
  });

  describe('find', () => {
    it(`should return user with name 'pipo'`, () => {
      const user = userServiceInterface.find('pipo');
      expect(user.username).toBe('pipo');
    });
  });
});

I've been looking for different ways to configure profiles, but importing them is the only way I've found.

Thanks in advance.

I figured out how nestjsx-automapper load profiles. As you can't provide profiles in modules, you depend on that the application runs the profiles first, and it is handled by AutomapperModule from nestjsx-automapper.

I don't know why nest Modules load AutomapperModule and consequently the profiles, but Test Modules doesn't, I will have to work more with nest to understand it.

To tell Test Modules to load AutomapperModule (as they don't by default) on init, use:

moduleRef.get(AutomapperModule).onModuleInit();
