Spring Boot单元测试

示例：使用Spring Boot单元测试

创建项目，修改pom.xml文件。

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

创建持久化类

程序清单：/jpa/src/main/java/com/dwx/bean/User.java

package com.dwx.bean;
public class User {
	private Integer userId;
	private String userName;
	private String sex;
	private Integer age;
	public User() {}
	public User(Integer userId, String userName, String sex, Integer age) {
		this.userId = userId;
		this.userName = userName;
		this.sex = sex;
		this.age = age;
	}
	public Integer getUserId() {
		return userId;
	}
	public void setUserId(Integer userId) {
		this.userId = userId;
	}
	public String getUserName() {
		return userName;
	}
	public void setUserName(String userName) {
		this.userName = userName;
	}
	public String getSex() {
		return sex;
	}
	public void setSex(String sex) {
		this.sex = sex;
	}
	public Integer getAge() {
		return age;
	}
	public void setAge(Integer age) {
		this.age = age;
	}
}

定义控制器类

程序清单：/jpa/src/main/java/com/dwx/controller/UserController.java

package com.dwx.controller;
import java.util.ArrayList;
import java.util.List;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;
import com.dwx.bean.User;
@RestController
@RequestMapping("/user")
public class UserController {
	@RequestMapping("/getUsers")
	public List<User> getUsers(){
		List<User> users=new ArrayList<User>();
		users.add(new User(1,"jack","男",22));
		users.add(new User(2,"lucy","女",18));
		return users;
	}
}

Controller单元测试

在src/test/java的com.dwx包下新建一个UserControllerTest.java

程序清单：/jpa/src/test/java/com/dwx/UserControllerTest.java

package com.dwx;
import org.junit.Before;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.http.MediaType;
import org.springframework.test.context.junit4.SpringRunner;
import org.springframework.test.web.servlet.MockMvc;
import org.springframework.test.web.servlet.request.MockMvcRequestBuilders;
import org.springframework.test.web.servlet.result.MockMvcResultHandlers;
import org.springframework.test.web.servlet.result.MockMvcResultMatchers;
import org.springframework.test.web.servlet.setup.MockMvcBuilders;
import org.springframework.web.context.WebApplicationContext;
@RunWith(SpringRunner.class)
@SpringBootTest(classes=JpaApplication.class)
public class UserControllerTest {
	@Autowired
	private WebApplicationContext wac;			//注入spring容器
	private MockMvc mvc;						//模拟http请求
	@Before
	public void setupMockMvc() {
		//初始化MockMvc对象
		mvc=MockMvcBuilders.webAppContextSetup(wac).build();
	}
	
	@Test
	public void getUsers() throws Exception {
		mvc.perform(MockMvcRequestBuilders.get("/user/getUsers")
				.contentType(MediaType.APPLICATION_JSON_UTF8)
				.accept(MediaType.APPLICATION_JSON_UTF8))
		.andExpect(MockMvcResultMatchers.status().isOk())
		.andDo(MockMvcResultHandlers.print());
	}
}

打开UserControllerTest测试类，选中getUsers方法，单击鼠标右键，选择“Run As”-----“JUnit Test”命令，切换到“Console”窗口，显示信息如下：
