当Mockito.()被调用时，Mockito调用它的mock？

设置如下：

@BeforeEach
void setUp() {
  mockAddressClient();
}

private void mockAddressClient() {
  Mockito
    .when(addressClient.addAddress(Mockito.any()))
    .thenAnswer(
      in -> {
        de.vbg.suvi.api.address.v1.model.Address adr = in.getArgument(0);
        de.vbg.suvi.api.address.v1.model.ValueAddress values = adr.getValues();
        AddressResponse addressResponse =
          new AddressResponse()
            .id(UUID.randomUUID())
            .streetLine1(values.getStreetLine1())
            .streetLine2(values.getStreetLine2())
            .streetNumber(values.getStreetNumber())
            .zipCode(values.getZipCode())
            .city(values.getCity())
            .country(values.getCountry());
        addresses.put(addressResponse.getId(), addressResponse);
        return new ResponseEntity<>(addressResponse, HttpStatus.CREATED);
    });
}

@Test
void postFullAccidentReport_firstWitnessAddressStreetNumberMissing() {
  /*
   * Given
   */
  final String placeId = UUID.randomUUID().toString();
  AccidentReport accidentReport = createFullAccidentReport();
  accidentReport.getFirstWitness().getPerson().getAddress().setPlaceId(placeId);
  accidentReport.getFirstWitness().getPerson().getAddress().setValues(null);
  Mockito.when(addressClient.addAddress(Mockito.argThat(a -> a.getPlaceId().equals(placeId))))
    .thenThrow(
      new ValidationException(
        List.of(
          new SuviFieldValidationError(
            ViolationCode.INVALID, "message", "streetNumber"))));

  /*
   * When
   */
  ResponseEntity<ValidationProblem> response =
    postAccidentReport(accidentReport, ValidationProblem.class);

  /*
   * Then
   */
  Assertions.assertEquals(HttpStatus.BAD_REQUEST, response.getStatusCode());
  Assertions.assertNotNull(response.getBody());
  ValidationProblem validationProblem = response.getBody();
  FieldViolation fieldViolation = validationProblem.getViolations().get(0);
  Assertions.assertEquals(
    "firstWitness.person.address.placeId.streetNumber", fieldViolation.getField());
}

现在，当我运行我的测试时，我在adr.getValues()上的mockAddressClient()方法中收到了一个NullPointerException。检查调用跟踪，看起来好像NPE在我的测试方法中的Mockito.when()行上抛出。好像Mockito正在调用它自己的mock。
以前有人经历过这种情况吗？设置错了吗？有什么办法绕过它？
编辑：模拟的注解是@MockBean。addAddress()的返回类型是ResponseEntity<AddressResponse>。

通过这种构造，您的thenThrow设置确实调用了mock上的方法，而不是设置它。
您可以使用替代的模拟设置来修复此问题，例如（为了便于阅读，示例不完整）：

Mockito.doThrow(myException).when(addressClient).addAddress(matchers)

在我自己的一个项目中验证了这一点。
如果Mockito随后抱怨这个mocking构造被认为是不必要的（在any上有一个匹配器，在argThat上有一个特定的匹配器），你可以在启用lenient的情况下设置它：

Mockito.lenient().doThrow(myException).when(addressClient).addAddress(matchers)

从https://www.baeldung.com/mockito-unnecessary-stubbing-exception开始
这基本上是因为在你的@BeforeEach中你设置了一个通用的答案，而在特定的测试postFullAccidentReport_firstWitnessAddressStreetNumberMissing中你希望它抛出一个Exception。所以第一个设置实际上并没有在这个测试方法中使用。
我猜想您有其他使用通用设置的测试方法，但是对于每种方法来说，正确的设置都是cleaner。
