SpringBoot测试用例

搭建一个简单Spring Boot的被测试环境
编写测试类
测试结果

@RunWith(SpringRunner.class)
如何运行这个测试类，这里用SpringRunner运行测试用例
@SpringBootTest
代表这是一个测试类
@Test
测试方法
WEB项目需一个MVC环境
搭建一个简单Spring Boot的被测试环境新建一个User对象

package com.user.domain; public class User { private String id; private String name; private Integer age; public String getId() { return id; } public void setId(String id) { this.id = id; } public String getName() { return name; } public void setName(String name) { this.name = name; } public Integer getAge() { return age; } public void setAge(Integer age) { this.age = age; }}

web层

package com.user.controll; import java.util.ArrayList; import java.util.List; import org.springframework.web.bind.annotation.GetMapping; import org.springframework.web.bind.annotation.RequestMapping; import org.springframework.web.bind.annotation.RestController; import com.user.domain.User; @RestController @RequestMapping("/user") public class UserControll { @GetMapping public List findAll() { List users = new ArrayList<>(); User user = new User(); user.setId("1"); user.setName("zhangsan"); user.setAge(18); users.add(user); return users; } @GetMapping("/{id}") public User getUserInfo(String id) { User user = new User(); user.setId("2"); user.setName("lisi"); user.setAge(18); return user; }}

编写测试类 【JAVA基础|SpringBoot测试用例】新建一个测试父类TestParent

package com.user; import org.junit.Before; import org.junit.runner.RunWith; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.boot.test.context.SpringBootTest; import org.springframework.test.context.junit4.SpringRunner; import org.springframework.test.web.servlet.MockMvc; import org.springframework.test.web.servlet.setup.MockMvcBuilders; import org.springframework.web.context.WebApplicationContext; @RunWith(SpringRunner.class) @SpringBootTest public class TestParent { @Autowired protected WebApplicationContext wac; //MVC环境 protected MockMvc mockMvc; @Before public void setup() { mockMvc = MockMvcBuilders.webAppContextSetup(wac).build(); }}

UserControllTest 测试类

package com.user.controll; import org.junit.Test; import org.springframework.http.MediaType; import org.springframework.test.web.servlet.request.MockMvcRequestBuilders; import org.springframework.test.web.servlet.result.MockMvcResultMatchers; import com.user.TestParent; public class UserControllTest extends TestParent { @Test public void whenQuerySuccess() throws Exception { mockMvc.perform(MockMvcRequestBuilders.get("/user") .param("username", "zhangsan") .contentType(MediaType.APPLICATION_JSON_UTF8)) .andExpect(MockMvcResultMatchers.status().isOk()) .andExpect(MockMvcResultMatchers.jsonPath("$.length()").value(1)); } @Test public void whenGetInfoSuccess() throws Exception { mockMvc.perform(MockMvcRequestBuilders.get("/user/2") .contentType(MediaType.APPLICATION_JSON_UTF8)) .andExpect(MockMvcResultMatchers.status().isOk()) .andExpect(MockMvcResultMatchers.jsonPath("$.name").value("lisi")); } }

测试结果方法上Run As -> JUnit Test则测试方法
类空白处上Run As -> JUnit Test则测试该测试类的所有@Test标注的方法
包上Run As -> JUnit Test则测试该包下所有测试类
