在调用给定的模拟void方法时执行自定义操作

Question

我想能够让Mockito在调用给定的void方法时执行自定义操作.

说我有以下代码:

@Autowired
private ProfileService profileService;

@Autowired
private ProfileDao profileDao;

private List<Profile> profiles;

@Before
public void setup() {
    Mockito.when(profileDao.findAll()).thenReturn(profiles);
    Mockito.when(profileDao.persist(any(Profile.class))).thenAddProfileToAboveList...
}

@Configuration
public static class testConfiguration {
    @Bean
    public ProfileDao ProfileDao() {
        return mock(ProfileDao.class);
    }
}

假设我想将配置文件实例添加到配置文件列表中.Mockito能做到吗？如果是这样的话？

Answer 1

使用Mockito.doAnswer.

doAnswer(new Answer() {
   public Object answer(InvocationOnMock invocation) {
       // make the changes you need here
   }})
 .when(mock).someMethod();
