1.pom.xml

一般使用idea新建一个SpringBoot web项目时，一般都会自动引入此依赖，如果没有，请手动引入。

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

1. spring-boot-start-test

SpringBoot提供了spring-boot-start-test启动器，该启动器提供了常见的单元测试库：

在单元测试中替代Get和Post请求测试方式

@RunWith(SpringRunner.class)
@SpringBootTest(webEnvironment = SpringBootTest.WebEnvironment.RANDOM_PORT)
public class ScoreControllerTestNew {
    @Autowired
    private TestRestTemplate restTemplate;
    @Test
    public void testScore(){
        String jsonStr = "{\"data\":{\"debit_account_balance_code\":40,\"credit_consume_count\":1,\"debit_start_age\":1,\"debit_consume_sum_code\":2,\"age\":38},\"modelProductId\":55}";
        String content = this.restTemplate.postForObject("/scoreApi/score", jsonStr, String.class );
        assertThat(content).isEqualTo("{\"result\":{\"score\":\"300\",\"logit\":21.144779999999997},\"response_code\":\"00\",\"response_msg\":\"success\"}");
    }
}

1、测试Controller

在测试Controller时需要进行隔离测试，这个时候需要Mock Service层的服务。

@RunWith(SpringRunner.class)
@WebMvcTest(ScoreController.class)
public class ScoreControllerTestNew {
    @Autowired
    private MockMvc mockMvc;

    @MockBean
    private ICalculateService calculateService;
    @MockBean
    private IModelMonitorService modelMonitorService;
    @MockBean
    private IScoreConfigService scoreConfigService;
    @MockBean
    private IModelProductService modelProductService;
    @Before
    public void setUp(){
    }
    @Test
    public void testScore() throws Exception {
        given(this.modelProductService.get(anyLong()))
                .willReturn(null);
        String jsonStr = "{\"data\":{\"debit_account_balance_code\":40,\"credit_consume_count\":1,\"debit_start_age\":1,\"debit_consume_sum_code\":2,\"age\":38},\"modelProductId\":5}";
        RequestBuilder requestBuilder = null;
        requestBuilder = post("/scoreApi/score").contentType(MediaType.APPLICATION_JSON).content(jsonStr);
        this.mockMvc.perform(requestBuilder).andExpect(status().isOk()).andExpect(MockMvcResultMatchers.content().string("{}"));
    }
}

2、测试Service

测试Service和测试Controller类似，同样采用隔离法。

@RunWith(SpringRunner.class)
@SpringBootTest
public class ServiceTest {
    @MockBean
    private ModelMonitorMapper modelMonitorMapper;
    @Autowired
    private IModelMonitorService modelServiceServiceImpl;
    @Test
    public void testModelServiceServiceImpl(){
        given(modelMonitorMapper.insert(anyObject()))
                .willReturn(0);
        int n =  modelServiceServiceImpl.insert(new ModelMonitor());
        assertThat(n).isEqualTo(0);
    }
}

3、测试Dao

测试的时候为了防止引入脏数据使用注解@Transactional和@Rollback在测试完成后进行回滚。

@RunWith(SpringRunner.class)
@SpringBootTest
@Transactional
public class ScoreControllerTestNew {

    @Autowired
    private ModelMonitorMapper modelMonitorMapper;
    @Test
    @Rollback
    public void testDao() throws Exception {
        ModelMonitor modelMonitor = new ModelMonitor();
        modelMonitor.setModelProductId(Long.parseLong("5"));
        modelMonitor.setLogit(21.144779999999997);
        modelMonitor.setDerivedVariables("{\"debit_account_balance_code\":1.0,\"credit_consume_count\":1.0,\"debit_start_age\":1.0,\"debit_consume_sum_code\":1.0,\"age\":1.0}");
        modelMonitor.setScore("300");
        modelMonitor.setSrcData("{\"data\":{\"debit_account_balance_code\":40,\"credit_consume_count\":1,\"debit_start_age\":1,\"debit_consume_sum_code\":2,\"age\":38},\"modelProductId\":5}");
        int n = modelMonitorMapper.insert(modelMonitor);
        assertThat(n).as("检查数据是否成功插入").isEqualTo(0);
    }
}
