스프링 부트 컨트롤러의 테스트 모델 속성

Question

단위 테스트를 처음 사용했습니다. 스프링 부트 애플리케이션 컨트롤러에 대한 테스트를하려고합니다. 그러나 테스트에서 내 모델 속성이나 그런 것을 찾을 수 없습니다. 아래에서 내 코드를 찾고 내가 잘못하고있는 것을 발견하는 데 도움이되기를 바랍니다. 미리 감사드립니다!

Answer 1

먼저 테스트 클래스에서 주석을 제거해야합니다. 주석은 통합 테스트에 사용되며 테스트가 느려지 게됩니다.

지금까지 문제가가는대로, 내 생각 엔 당신의 RestaurantFilter 당신이

when(restaurantService.findByNameIgnoreCaseContaining(filter)) 
    .thenReturn(Arrays.asList(first, second)); 

Mockito에서 사용할 때 아무튼 그래서 equals 및 hashCode 그래서 실제로 모의에 인수 일치하지 않는 구현하지 않는다는 것입니다 당신이 준 배열을 반환하지 않습니다. 당신은 equals 및 hashCode를 구현해야 하나 또는, 빠르지 만 가능성이 더 오류가 발생하기 쉬운으로 when(...) 정의를 대체 :

when(restaurantService.findByNameIgnoreCaseContaining(refEq(filter))) 
    .thenReturn(Arrays.asList(first, second)); 

Matchers.refEq이 반사를 사용하여 값을 비교하고 .equals 비교에 의존하지 않습니다.
