这是我的仓库

@Injectable()
export class MyRepository extends Repository<MyData> {
  constructor(private dataSource: DataSource) {
    super(MyData, dataSource.createEntityManager());
  }
}

和spec文件

beforeEach(async () => {
    const module: TestingModule = await Test.createTestingModule({
      controllers: [MyController],
      providers: [
        MyService,
        MyRepository ,

      ],
    }).compile();

但我正在面对

Nest can't resolve dependencies of the MyRepository (?). Please make sure that the argument DataSource at index [0] is available in the RootTestModule context.

有人帮忙吗？
