SpringJUnit4ClassRunner+mockito 进程feign接口进行单元测试

1、引入 jar

<dependency>
       <groupId>org.springframework.boot</groupId>
       <artifactId>spring-boot-starter-test</artifactId>
       <scope>test</scope>
</dependency>

 2、被测试的类

@Service
@CustomLog
@Transactional(rollbackFor = Exception.class)
public class CasMonitorTaskServiceTx {

    @Autowired
    private WoMonitorTaskMapper woMonitorTaskMapper;
    @Autowired
    private WoMonitorRecordMapper woMonitorRecordMapper;
    @Autowired
    private SmsSendLogMapper smsSendLogMapper;
    @Autowired
    private SmsRecordClient smsRecordClient;



    public void insertRecordAndSendSms() throws SchedulerException {
       
    }
}

3、单元测试类

@ContextConfiguration(locations = {"classpath:test-service.xml", "classpath*:spring/root/public-*.xml"})
@RunWith(SpringJUnit4ClassRunner.class)
@Transactional
public class CasMonitorTaskServiceTxTest {

    @Autowired
    private CasMonitorTaskServiceTx casMonitorTaskServiceTx;

   
    @MockBean
    private SmsRecordClient client;

    @Test
    public void insertRecordAndSendSms() throws Exception {
        SmsRecordApi.SendRes res = new SmsRecordApi.SendRes();
        res.setMessage(Message.builder().ok(SmsRecordApi.SendRes.SendRes_Message.class));
        Mockito.doReturn(res).when(client).send(any());
        
        Long recordId = casMonitorTaskServiceTx.insertRecordAndSendSms();
        System.out.println(recordId);
    }

  
}

说明： 

CasMonitorTaskServiceTx类中除 SmsRecordClient之外的 bean 继续使用 spring容器进行加载 只需要mock feign 接口 SmsRecordClient，故在 test类中 mock SmsRecordClient类+注解 @MockBean

• Mock一般用在不依赖框架的单元测试
• MockBean用在依赖Spring上下文环境
