Spring Boot从Controller层进行单元测试的实现

单元测试是程序员对代码的自测，一般公司都会严格要求单元测试，这是对自己代码的负责，也是对代码的敬畏。

一般单元测试都是测试Service层，下面我将演示从Controller层进行单元测试。

无参Controller单元测试示例：

package com.pingan.bloan.genesis.controller.base;

import org.junit.After;
import org.junit.Before;
import org.junit.runner.RunWith;
import com.pingan.bloan.genesis.logwrapper.LogWrapper;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.test.context.junit4.SpringRunner;
import com.pingan.bloan.genesis.logwrapper.LogWrapperFactory;
import org.springframework.test.context.web.WebAppConfiguration;

@RunWith(SpringRunner.class)
@SpringBootTest
@WebAppConfiguration
public class baseSpringBootTest {
  protected LogWrapper logger = LogWrapperFactory.getLogWrapper(baseSpringBootTest.class);
  
  @Before
  public void init() {
    logger.info("开始测试...");
  }
  
  @After
  public void after() {
    logger.info("测试结束...");
  }
}

package com.pingan.bloan.genesis.controller;

import org.junit.Test;
import org.junit.Before;
import org.springframework.test.web.servlet.MockMvc;
import org.springframework.test.web.servlet.MvcResult;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.test.web.servlet.setup.MockMvcBuilders;
import com.pingan.bloan.genesis.controller.base.baseSpringBootTest;
import org.springframework.test.web.servlet.result.MockMvcResultHandlers;
import org.springframework.test.web.servlet.result.MockMvcResultMatchers;
import org.springframework.test.web.servlet.request.MockMvcRequestBuilders;


public class DemoControllerTest extends baseSpringBootTest {
  @Autowired
  private DemoController demoController;
  
  private MockMvc mockMvc;
  
  @Before
  public void setup() {
    mockMvc = MockMvcBuilders.standaloneSetup(demoController).build();
  }
  
  @Test
  public void demo() throws Exception {
    MvcResult mvcResult = mockMvc.perform(MockMvcRequestBuilders.get("/demo/demo"))
     .andExpect(MockMvcResultMatchers.status().isOk())
     .andDo(MockMvcResultHandlers.print())
     .andReturn();

    logger.info(mvcResult.getResponse().getContentAsString());
  }
}

有参Controller单元测试示例一：

package com.pingan.bloan.genesis.controller;

import org.junit.Test;
import org.junit.Before;
import org.springframework.http.MediaType;
import org.springframework.test.web.servlet.MockMvc;
import org.springframework.test.web.servlet.MvcResult;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.test.web.servlet.setup.MockMvcBuilders;
import com.pingan.bloan.genesis.controller.base.baseSpringBootTest;
import org.springframework.test.web.servlet.result.MockMvcResultHandlers;
import org.springframework.test.web.servlet.result.MockMvcResultMatchers;
import org.springframework.test.web.servlet.request.MockMvcRequestBuilders;


public class MessageEncryptionControllerTest extends baseSpringBootTest {
  @Autowired
  private MessageEncryptionController messageEncryptionController;
  
  private MockMvc mockMvc;
  
  @Before
  public void setup() {
    mockMvc = MockMvcBuilders.standaloneSetup(messageEncryptionController).build();
  }
  
  
  @Test
  public void encryption() throws Exception {
    MvcResult mvcResult = mockMvc.perform(MockMvcRequestBuilders.post("/secret/encryption")
     .accept(MediaType.APPLICATION_JSON).param("originContent", "15221365094"))
     .andExpect(MockMvcResultMatchers.status().isOk())
     .andDo(MockMvcResultHandlers.print())
     .andReturn();
    
    logger.info(mvcResult.getResponse().getContentAsString());
  }
  
  
  @Test
  public void deciphering() throws Exception {
    MvcResult mvcResult = mockMvc.perform(MockMvcRequestBuilders.post("/secret/deciphering")
     .accept(MediaType.APPLICATION_JSON).param("secretContent", "4BD6EE1A13593F97E6CEA20A2BA9E6E4"))
     .andExpect(MockMvcResultMatchers.status().isOk())
     .andDo(MockMvcResultHandlers.print())
     .andReturn();

    logger.info(mvcResult.getResponse().getContentAsString());
  }
}

有参Controller单元测试示例二：

package com.pingan.bloan.genesis.controller;

import org.junit.Test;
import org.junit.Before;
import com.alibaba.fastjson.JSONObject;
import org.springframework.http.MediaType;
import org.springframework.test.web.servlet.MockMvc;
import org.springframework.test.web.servlet.MvcResult;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.test.web.servlet.setup.MockMvcBuilders;
import com.pingan.bloan.genesis.controller.base.baseSpringBootTest;
import org.springframework.test.web.servlet.result.MockMvcResultHandlers;
import org.springframework.test.web.servlet.result.MockMvcResultMatchers;
import org.springframework.test.web.servlet.request.MockMvcRequestBuilders;
import com.pingan.bloan.genesis.model.mobiletelephone.MobileTelephoneRequest;


public class MobileTelephoneIdempotentControllerTest extends baseSpringBootTest {
  @Autowired
  private MobileTelephoneIdempotentController mobileTelephoneIdempotentController;
  
  private MockMvc mockMvc;
  
  @Before
  public void setup() {
    mockMvc = MockMvcBuilders.standaloneSetup(mobileTelephoneIdempotentController).build();
  }
  
  
  @Test
  public void saveCustomerEncryptionMessage() throws Exception {
    MobileTelephoneRequest request = new MobileTelephoneRequest();
    request.setCustomerId("RL20180304000099");
    request.setMobileTelephone("18883270484");
    request.setCcfMobileTelephone("13904108866");
    
    MvcResult mvcResult = mockMvc.perform(MockMvcRequestBuilders.post("/customerEncryption/save")
     .contentType(MediaType.APPLICATION_JSON)
     .content(JSONObject.toJSonString(request)))
     .andExpect(MockMvcResultMatchers.status().isOk())
     .andDo(MockMvcResultHandlers.print())
     .andReturn();
    
    logger.info(mvcResult.getResponse().getContentAsString());
  }
}

Suite一次性执行多个单元测试：

package com.pingan.bloan.genesis.controller;

import org.junit.runners.Suite;
import org.junit.runner.RunWith;


@RunWith(Suite.class)
@Suite.SuiteClasses({MessageEncryptionControllerTest.class, DemoControllerTest.class})
public class SuiteExecuteTests {
  // 不用写代码,只需要注解即可(在SuiteClasses中配置测试类)
}

代码单元测试，让代码更加健壮。
