org.assertj.core.error.AssertJMultipleFailuresError: Multiple Failures (1 failure) -- failure 1 -- Expecting actual: LetterResponse[id=1, player=com.now.naaga.player.presentation.dto.PlayerResponse@3d573851, coordinate=CoordinateResponse[latitude=37.515446, longitude=127.102899], message=안녕하세요. 나아가 개발자들 입니다., registerDate=2023-10-13T14:14:41.922818] to be equal to: LetterResponse[id=1, player=com.now.naaga.player.presentation.dto.PlayerResponse@282bc2de, coordinate=CoordinateResponse[latitude=37.515446, longitude=127.102899], message=안녕하세요. 나아가 개발자들 입니다., registerDate=2023-10-13T14:14:41.922817913] when recursively comparing field by field, but found the following difference: field/property 'registerDate' differ: - actual value : "2023-10-13T14:14:41.922818" - expected value: "2023-10-13T14:14:41.922817913" The recursive comparison was performed with this configuration: - all expected null fields were ignored in the comparison - no overridden equals methods were used in the comparison (except for java types) - these types were compared with the following comparators: - java.lang.Double -> DoubleComparator[precision=1.0E-15] - java.lang.Float -> FloatComparator[precision=1.0E-6] - java.nio.file.Path -> lexicographic comparator (Path natural order) - actual and expected objects and their fields were compared field by field recursively even if they were not of the same type, this allows for example to compare a Person to a PersonDto (call strictTypeChecking(true) to change that behavior). - the introspection strategy used was: DefaultRecursiveComparisonIntrospectionStrategy at LetterControllerTest.lambda$쪽지_식별자로_쪽지를_조회한다$0(LetterControllerTest.java:100)
