Mockito 模拟未被调用 - ArgumentCaptor 被忽略

Question

我想在 UserServiceImplV1 类上测试以下代码：

    @Override
    public void updateUserPassword(VerificationCodeDTO code, String newPassword) {
        if(verificationCodeService.isValid(code)) {
            UserDTOV1 user = userService.findByEmail(code.getEmail());
            user.setPassword(newPassword);
            userService.save(user);
            verificationCodeService.delete(code.getEmail());
        } else {
            throw new ValidationException("Código de usuário inválido");
        }
    }

于是我写了如下测试：

@Test
    public void updatesUserPasswordAndDeletesToken() {
        UserDTOV1 userDTO = new UserDTOV1("John", "a@mail.com", "123", UserType.PESSOAFISICA, "oldPassword");
        VerificationCodeDTO verificationCodeDTO = new VerificationCodeDTO("abcd", userDTO.getEmail());

        when(verificationCodeService.isValid(any())).thenReturn(Boolean.TRUE);
        when(userService.findByEmail("a@mail.com")).thenReturn(userDTO);
        when(userService.save(any(UserDTOV1.class))).thenAnswer(invocation -> invocation.getArgument(0));
        ArgumentCaptor<UserDTOV1> captor = ArgumentCaptor.forClass(UserDTOV1.class);
        verify(userService, times(1)).save(captor.capture());
        UserDTOV1 actual = captor.getValue();

        authService.updateUserPassword(verificationCodeDTO, "newPassword");
        Assert.assertEquals("newPassword", actual.getPassword());
        verify(verificationCodeService, times(1)).delete(anyString());
    }

我收到以下错误：

Wanted but not invoked:
userService.save(<Capturing argument>);
-> at (...).updatesUserPasswordAndDeletesToken(AuthServiceImplV1Test.java:45)
Actually, there were zero interactions with this mock.

我尝试了很多方法来捕获参数，比如

verify(userService, times(1)).save(argThat(argument -> argument.getPassword().equals("newPasword")));

但是错误是一样的，几乎就像我的模拟没有被应用一样。不过，我正在创建它们，并且此文件中的所有其他测试都有效：

@RunWith(MockitoJUnitRunner.class)
public class AuthServiceImplV1Test {
    @Mock
    private UserServiceImplV1 userService;

    @Mock
    private VerificationCodeServiceImplV1 verificationCodeService;

    @InjectMocks
    private AuthServiceImplV1 authService;

提前致谢。

您正在验证在调用被测方法之前调用了模拟。所以那时，还没有调用 mock。
