單元測試是程式設計師對程式碼的自測，一般公司都會嚴格要求單元測試，這是對自己程式碼的負責，也是對程式碼的敬畏。

一般單元測試都是測試Service層，下面我將演示從Controller層進行單元測試。

無參Controller單元測試示例：

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("開始測試...");
  }
  
  @After
  public void after() {
    logger.info("測試結束...");
  }
}

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;

/**
 * DemoController測試
 * @author 
 *
 */
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());
  }
}

有參Controller單元測試示例一：

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;

/**
 * 加解密controller測試
 * 
 * @author 
 *
 */
public class MessageEncryptionControllerTest extends BaseSpringBootTest {
  @Autowired
  private MessageEncryptionController messageEncryptionController;
  
  private MockMvc mockMvc;
  
  @Before
  public void setup() {
    mockMvc = MockMvcBuilders.standaloneSetup(messageEncryptionController).build();
  }
  
  /**
   * 加密測試
   * @throws Exception 
   */
  @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());
  }
  
  /**
   * 解密測試
   * @throws Exception 
   */
  @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());
  }
}

有參Controller單元測試示例二：

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;

/**
 * 客戶手機掩碼資訊加密處理測試
 * @author 
 *
 */
public class MobileTelephoneIdempotentControllerTest extends BaseSpringBootTest {
  @Autowired
  private MobileTelephoneIdempotentController mobileTelephoneIdempotentController;
  
  private MockMvc mockMvc;
  
  @Before
  public void setup() {
    mockMvc = MockMvcBuilders.standaloneSetup(mobileTelephoneIdempotentController).build();
  }
  
  /**
   * 儲存加密處理的客戶資訊
   * @throws Exception 
   */
  @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一次性執行多個單元測試：

package com.pingan.bloan.genesis.controller;

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

/**
 * 打包測試
 * 配置測試類，一次性執行所有配置的測試類
 * @author 
 *
 */
@RunWith(Suite.class)
@Suite.SuiteClasses({MessageEncryptionControllerTest.class,DemoControllerTest.class})
public class SuiteExecuteTests {
  // 不用寫程式碼,只需要註解即可(在SuiteClasses中配置測試類)
}

程式碼單元測試，讓程式碼更加健壯。
