사용자 범위 파인더로 전환 한 후 Rspec 테스트가 실패했습니다.

Question

그래서 작은 작업 추적 애플리케이션을 작성하여 레일 학습을 시작했습니다. 이제 리팩토링을 좀 더 안전하게하려고 노력 중입니다. 예를 들어 업데이트 또는 파기 전에 범위를 사용하여 자신의 작업을보고 있는지 확인합니다.

그러나이 작업을 수행하면 세 가지 테스트가 더 이상 진행되지 않으며 문제를 해결하는 방법을 모르겠습니다. 내가 도대체 ​​뭘 잘못하고있는 겁니까? 테스트를 변경해야합니까, 아니면 공장에서 무언가를하는 것을 잊었습니까?

감사합니다.
