TypeOrm自定义仓库迁移至NestJs可注入提供者的测试问题

已将TypeORM升级至0.3.12版本，@nestjs/typeorm升级至9.0.1版本，按参考方案完成所有自定义仓库迁移后，测试时将依赖添加至createTestingModule的providers元数据仍无法正常运行。怀疑dailyTaskRepository = module.get<TypeOrmDailyTaskRepository>(TypeOrmDailyTaskRepository)这行获取实例的代码已过时，但不清楚当前如何从模块中获取提供者实例。

环境版本 #

• TypeORM: 0.3.12
• @nestjs/typeorm: 9.0.1

      new DailyTask(dailyTasksFixtures[1]),
    ]

    const retrievedDailyTasks = await dailyTaskRepository.getAll()

    expect(retrievedDailyTasks).toStrictEqual(expectedDailyTasks)

    Nest无法解析DailyTask的依赖(?)。请确保索引[0]处的参数Object在RootTestModule上下文中可用。

    可能的解决方案：
    - 如果Object是提供者，它是否属于当前RootTestModule？
    - 如果Object是从独立@Module导出的，该模块是否已在RootTestModule中导入？
      @Module({
        imports: [ /* 包含Object的模块 */ ]
