Inject TypeORM repository into NestJS service for mock data testing

Question

There\'s a longish discussion about how to do this in this issue.

I\'ve experimented with a number of the proposed solutions but I\'m not having much luck.

I also found that this worked for me:

export const mockRepository = jest.fn(() => ({
  metadata: {
    columns: [],
    relations: [],
  },
}));

and

const module: TestingModule = await Test.createTestingModule({
      providers: [{ provide: getRepositoryToken(Entity), useClass: mockRepository }],
    }).compile();
