一、整合junit4

• Maven依赖

  <!--   spring框架     -->
  <dependency>
      <groupId>org.springframework</groupId>
      <artifactId>spring-context</artifactId>
      <version>5.2.2.RELEASE</version>
  </dependency>
  <dependency>
      <groupId>org.springframework</groupId>
      <artifactId>spring-jdbc</artifactId>
      <version>5.2.2.RELEASE</version>
  </dependency>
  <dependency>
      <groupId>org.springframework</groupId>
      <artifactId>spring-test</artifactId>
      <version>5.2.2.RELEASE</version>
      <scope>test</scope>
  </dependency>
  <dependency>
       <!--     junit4       -->
       <groupId>junit</groupId>
       <artifactId>junit</artifactId>
       <version>4.13</version>
       <scope>test</scope>
   </dependency>
  

• 配置文件，开启扫描

  <?xml version="1.0" encoding="UTF-8"?>
  <beans xmlns="http://www.springframework.org/schema/beans"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xmlns:context="http://www.springframework.org/schema/context"
         xsi:schemaLocation="http://www.springframework.org/schema/beans
         http://www.springframework.org/schema/beans/spring-beans.xsd
         http://www.springframework.org/schema/context
         http://www.springframework.org/schema/context/spring-context.xsd
  ">
      <context:component-scan base-package="com.du.spring"/>
  
  </beans>
  

• 调用

  @RunWith(SpringJUnit4ClassRunner.class) //单元测试框架
  @ContextConfiguration("classpath:bean.xml") // 加载配置文件
  public class UserTest {
    @Autowired
    private User user;
  
    @Test
    public void test() {
      Integer id = user.getId();
      System.out.println(id);
      user.setId(null);
      System.out.println(user);
    }
  }
  

二、整合junit5

• Maven依赖

  <!--   spring框架     -->
  <dependency>
      <groupId>org.springframework</groupId>
      <artifactId>spring-context</artifactId>
      <version>5.2.2.RELEASE</version>
  </dependency>
  <dependency>
      <groupId>org.springframework</groupId>
      <artifactId>spring-jdbc</artifactId>
      <version>5.2.2.RELEASE</version>
  </dependency>
  <dependency>
      <groupId>org.springframework</groupId>
      <artifactId>spring-test</artifactId>
      <version>5.2.2.RELEASE</version>
      <scope>test</scope>
  </dependency>
  <!-- https://mvnrepository.com/artifact/org.junit.jupiter/junit-jupiter-api -->
  <!--   junit5     -->
  <dependency>
      <groupId>org.junit.jupiter</groupId>
      <artifactId>junit-jupiter-api</artifactId>
      <version>5.7.0</version>
      <scope>test</scope>
  </dependency>
  

• 调用

  //@ExtendWith(SpringExtension.class)
  //@ContextConfiguration("classpath:bean.xml") // 加载配置文件
  @SpringJUnitConfig(locations = "classpath:bean.xml")  // 下面一句顶上面两句
  public class UserTest {
    @Autowired
    private User user;
  
    @Test
    public void test() {
      Integer id = user.getId();
      System.out.println(id);
      user.setId(null);
      System.out.println(user);
    }
  }
  

三、Spring MVC 整合 Junit5

参考文档

• SpringMVC 模拟器，可以模拟页面请求，对Controller进行测试

  @SpringJUnitWebConfig(locations = {"classpath:springmvc-servlet.xml", "classpath:applicationContext.xml"})
  public class EmployeeControllerTest {
    MockMvc mockMvc;
    // 固定写法，复制粘贴就好
    @BeforeEach
    void setup(WebApplicationContext wac) {
      this.mockMvc = MockMvcBuilders.webAppContextSetup(wac).build();
    }
  
    @Test
    public void getEmpsTest() throws Exception {
      // 获得一个模拟的请求建造器
      MockHttpServletRequestBuilder requestBuilder = MockMvcRequestBuilders.get("/getEmps");
      // 模拟器工作，获得一个结果
      MvcResult result = mockMvc.perform(requestBuilder).andReturn();
      // 从结果中获取请求出来
      MockHttpServletRequest request = result.getRequest();
      PageInfo pageInfo = (PageInfo) request.getAttribute("pageInfo");
      System.out.println("当前页码" + pageInfo.getPageNum());
      for (int navigatepageNum : pageInfo.getNavigatepageNums()) {
        System.out.print(navigatepageNum + " ");
      }
    }
  }
