spring-boot单元测试

1、pom.xml中添加配置spring-boot-starter-test

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

2、在src/main/java目录下创建Controller

package com.generalichina.cimc.controller;

import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

@RestController
public class IndexController {
    @RequestMapping("/index")
    public String index() {
        return "index";
    }
}

3、在src/test/java目录下创建Controller的测试类

package com.generalichina.cimc.controller;

import org.junit.Before;
import org.junit.Test;
import org.junit.runner.RunWith;
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.setup.MockMvcBuilders;
import static org.hamcrest.Matchers.equalTo;
import static org.springframework.test.web.servlet.result.MockMvcResultMatchers.content;
import static org.springframework.test.web.servlet.result.MockMvcResultMatchers.status;
@RunWith(SpringRunner.class)
@SpringBootTest
public class IndexControllerTests {
    //    @Autowired
//    private WebApplicationContext context;

    //mock api 模拟http请求
    private MockMvc mockMvc;

    //初始化工作
    @Before
    public void setUp() {
        //独立安装测试
        mockMvc = MockMvcBuilders.standaloneSetup(new IndexController()).build();
        //集成Web环境测试（此种方式并不会集成真正的web环境，而是通过相应的Mock API进行模拟测试，无须启动服务器）
        //mockMvc = MockMvcBuilders.webAppContextSetup(context).build();
    }

    //测试
    @Test
    public void index() throws Exception {
        mockMvc.perform(MockMvcRequestBuilders.get("/index")
                .accept(MediaType.APPLICATION_JSON))
                .andExpect(status().isOk())
                .andExpect(content().string(equalTo("index")));
    }

}

运行index测试:

显示测试通过,ok
