我正在email-service.spec.ts文件中编写测试用例
我的电子邮件服务文件

@Injectable()
export class EmailSubscriptionService {
  private nodeTokenCache;
  private result;
  constructor(@InjectRepository(ConsumerEmailSubscriptions) private readonly emailSubscriptions: Repository<ConsumerEmailSubscriptions>,
    @InjectRepository(EmailSubscriptions) private readonly emailSubscriptionLegacy: Repository<EmailSubscriptions>,
    @InjectRedisClient('0') private redisClient: Redis.Redis,
     private readonly config: ConfigService, private http: HttpService,
    private readonly manageSavedSearchService: ManageSavedSearchService) {
  }

我的email-service.spec.ts文件

import { RedisService } from 'nestjs-redis';
import { ConfigService } from '@nestjs/config';
import { HttpService } from '@nestjs/common';
import { ManageSavedSearchService } from './../manage-saved-search/manage-saved-search.service';

describe('EmailSubscriptionService', () => {
  let service: EmailSubscriptionService;
  let entity : ConsumerEmailSubscriptions;

  beforeEach(async () => {
    const module: TestingModule = await Test.createTestingModule({
      imports:[RedisModule],

      // https://github.com/nestjs/nest/issues/1229
      providers: [EmailSubscriptionService,
        {
          // how you provide the injection token in a test instance
          provide: getRepositoryToken(ConsumerEmailSubscriptions),
          // as a class value, Repository needs no generics
          useClass: Repository,
          // useValue: {

          // }
        }, 
        {
          provide: getRepositoryToken(EmailSubscriptions),
          useClass: Repository,
        },
        RedisService,
        // {
        //   provide : RedisService,
        //   useClass: Redis
        // },

       ConfigService, HttpService, ManageSavedSearchService

      ],
    }).compile();

    service = module.get<EmailSubscriptionService>(EmailSubscriptionService);
    // entity = module.get<Repository<ConsumerEmailSubscriptions>>(getRepositoryToken(ConsumerEmailSubscriptions));

  });

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

结果---->nest无法解析emailsubscriptionservice（ConsumerMailSubscriptionsRepository、emailsubscriptionsrepository、？configservice、httpservice、managesavedsearchservice）的依赖项。请确保索引[2]处的参数redis\u client\u provider\u 0在roottestmodule上下文中可用。
根据服务文件中的依赖关系，我无法在email-service.spec.ts中模拟我的redisclient。我尝试过useclass，在provide中添加了redisservice，但是没有get redis方法。我能够模仿存储库和服务，我不确定，因为我被redis困住了。
如果你知道如何模仿redis，在文档里找不到任何东西。同样在下一步中，导入服务会起作用还是我必须做其他事情？configservice、httpservice、managesavedsearchservice:managesavedsearchservice
