一、引入依赖
<dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-test</artifactId> <scope>test</scope> </dependency> <dependency> <groupId>junit</groupId> <artifactId>junit</artifactId> <version>4.11</version> <scope>test</scope> </dependency>
二、测试代码
package com.example; import com.example.pojo.Book; import com.example.service.BookService; 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.MockMvcResultMatchers; import org.springframework.test.web.servlet.setup.MockMvcBuilders; import org.springframework.web.context.WebApplicationContext; import javax.annotation.Resource; import java.util.List; @RunWith(SpringRunner.class)//用SpringRunner执行测试用例 @SpringBootTest//这是一个测试类 public class BookControllerTest { @Resource private BookService bookService; @Autowired private WebApplicationContext wac; private MockMvc mockMvc; @Before//伪造一个测试环境，不用启动tomcat,会在每次执行测试用例前执行 public void setup(){ mockMvc = MockMvcBuilders.webAppContextSetup(wac).build(); } @Test public void findAllTest() throws Exception{ // List<Book> list = bookService.getAllBooks(); // System.out.println("=====findAllTest======="+list.toString()); // for(int i=0;i<list.size();i++){ // System.out.println(i+"------"+list.get(i).getName()); // } //执行/findAll请求 mockMvc.perform(MockMvcRequestBuilders.get("/findAll") //使用UTF8编码 .contentType(MediaType.APPLICATION_JSON_UTF8)) //希望返回状态码是 isOk() 即：200 .andExpect(MockMvcResultMatchers.status().isOk()) //希望返回的长度是7 .andExpect(MockMvcResultMatchers.jsonPath("$.length()").value(7)); } }
MockMvcResultMatchers.jsonPath 表达式
