我有一個測試來驗證空對象的返回（如果該對象的字符串屬性與預先確定的值不匹配）。我的代碼是import guru.springframework.sfgpetclinic.model.Speciality;import guru.springframework.sfgpetclinic.repositories.SpecialtyRepository;import org.junit.jupiter.api.Test;import org.junit.jupiter.api.extension.ExtendWith;import org.mockito.InjectMocks;import org.mockito.Mock;import org.mockito.Mockito;import org.mockito.junit.jupiter.MockitoExtension;import java.util.Optional;import static org.assertj.core.api.Assertions.assertThat;import static org.junit.jupiter.api.Assertions.assertThrows;import static org.mockito.BDDMockito.*;import static org.junit.jupiter.api.Assertions.*;import static org.mockito.BDDMockito.given;import static org.mockito.BDDMockito.then;@ExtendWith(MockitoExtension.class)class SpecialtySDJpaServiceTest {    @Mock    SpecialtyRepository specialtyRepository;    @InjectMocks    SpecialtySDJpaService service;    @Test    void testSaveLambdaNoMatch() {       // Given       final String MATCH_ME = "MATCH_ME";       Speciality speciality = new Speciality();       speciality.setDescription("Not a match");       Speciality savedSpeciality = new Speciality();       savedSpeciality.setId(1L);       // Need mock to only return on match MATCH_ME string       given(specialtyRepository.save(argThat(argument -> argument.getDescription().equals(MATCH_ME)))).willReturn(savedSpeciality);       // When       Speciality returnedSpeciality = service.save(speciality);       // Then       assertNull(returnedSpeciality);    }   // Other tests...}此測試失敗并顯示消息org.mockito.exceptions.misusing.PotentialStubbingProblem: Strict stubbing argument mismatch. Please check:- this invocation of 'save' method:specialtyRepository.save(guru.springframework.sfgpetclinic.model.Speciality@19ae6bb我認為問題在于 argThat() 使用精確匹配方案。我想將模擬匹配設置為寬松通過@Mock(lenient = true)SpecialtyRepository specialtyRepository 但 Intellij 不識別 lenient 參數。我正在使用 JUnit 5 和 Mockito 2.23.0
