230621 실전프로젝트20 [Nest.js] Jest로 Unit test code 짜기

프로젝트 마무리 단계에 접어들었고 CI/CD를 위한 UNIT TEST CODE 작성을 시작했다. 

 

✅오늘 겪은 문제

아래와 같은 에러가 떴다. 

 ● StoresRepository › updateCoord › 카톡에서 추출한 좌표를 postgresql에 저장

    Nest can't resolve dependencies of the StoresRepository (StoresRepository, ?). Please make sure that the argument TablesRepository at index [1] is available in the RootTestModule context.

    Potential solutions:
    - Is RootTestModule a valid NestJS module?
    - If TablesRepository is a provider, is it part of the current RootTestModule?
    - If TablesRepository is exported from a separate @Module, is that module imported within RootTestModule?
      @Module({
        imports: [ /* the Module containing TablesRepository */ ]
      })

에러의 내용을 살펴보면 TablesRepository가  StoresRepository의 의존성으로 등록되어있지 않다는 뜻인데, 

실제로 StoresRepository에 TablesRepository가 등록되어 있었지만 더이상 프로젝트에서 Tables 는 쓰이지 않기에 삭제해주었더니 해결되었다. 

 

✅오늘 알게된 점 및 추후 학습 방향

 service부분의 testcode도 구현할 예정이다.
