인프런 커뮤니티 질문&답변

안녕하세요

강의가 너무 좋아서 한번더 퀵하게 복습 중인데, 그 사이에 mongoose의 메이저버전이 6으로 올라갔습니다.

getProducts 통합 테스트할때, 전체 테스트(npm test)를 하면 오류가 안나지만, jest extension을 이용해서 아래 테스트만 진행하면 오류가 나네요.

it('GET /products', async () => {
  const res = await request(app).get('/products');
  expect(res.statusCode).toBe(200);
  expect(Array.isArray(res.body)).toBeTruthy();
  expect(res.body[0].name).toBeDefined();
  expect(res.body[0].description).toBeDefined();
});

검색해서 좀 알아봐도 뚜렷한 답이 안나와서 혹시 아시는 내용인지 문의 드립니다.

참고로 결과 공유 드립니다

Jest did not exit one second after the test run has completed.

This usually means that there are asynchronous operations that weren't stopped in your tests. Consider running Jest with `--detectOpenHandles` to troubleshoot this issue.
