mockMVC

引入依赖

<!-- junit5 spring-test-->
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-test</artifactId>
            <scope>test</scope>
        </dependency>

编写测试类

package boot;

import org.junit.jupiter.api.Test;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.autoconfigure.web.servlet.AutoConfigureMockMvc;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.http.MediaType;
import org.springframework.test.web.servlet.MockMvc;
import org.springframework.test.web.servlet.ResultActions;
import org.springframework.test.web.servlet.request.MockMvcRequestBuilders;
import org.springframework.test.web.servlet.result.MockMvcResultHandlers;
import org.springframework.test.web.servlet.result.MockMvcResultMatchers;

@SpringBootTest
@AutoConfigureMockMvc
public class MockMvcTest {

    @Autowired
    MockMvc mockMvc;

    //无需依赖web网络环境，无需启动应用，可直接请求controller
    @Test
    void testMockMVC() throws Exception {
        //发起一个模拟请求
        mockMvc.perform(
                MockMvcRequestBuilders.get("/getUser")  //发送get请求
                        .accept(MediaType.APPLICATION_JSON)  //设置响应的文本类型
        )
        .andExpect(MockMvcResultMatchers.status().isOk())//断言状态码为200
        .andDo(MockMvcResultHandlers.print());
    }

    @Test
    void testMockMVCPost() throws Exception {
        mockMvc.perform(
                        MockMvcRequestBuilders.post("/updateUser")  //发送get请求
                                .accept(MediaType.APPLICATION_JSON)  //设置响应的文本类型
                                .contentType(MediaType.APPLICATION_JSON_UTF8)//设置请求的文本类型
                                .content("{\"name\":\"lisi\",\"age\":20}")
                ).andExpect(MockMvcResultMatchers.status().isOk())
                .andExpect(MockMvcResultMatchers.jsonPath("$.name").value("lisi"))//断言
                .andDo(MockMvcResultHandlers.print());
    }
}
