使用虚拟MVC请求进行单元测试Controller层方法

应用场景：表现层代码在测试时，需要部署服务器，启动服务器测试，对于频繁的测试，由于服务器启动缓慢，测试起来很不方便。
spring-test提供了虚拟mvc请求，可以模拟请求进行测试

需要jar包：spring-test.jar

@ContextConfiguration(locations = {"classpath:applicationContext.xml","classpath:springmvc.xml"})
@WebAppConfiguration//此注解为WebApplicationContext从springmvc IOC中取出赋值
@RunWith(SpringJUnit4ClassRunner.class)
public class UserMVCTest {
    @Autowired
    private WebApplicationContext context;
    //虚拟mvc请求
    private MockMvc mockMvc;
    //初始化mockMvc
    @Before
    public void initMockMvc(){
        mockMvc = MockMvcBuilders.webAppContextSetup(context).build();
    }
    @Test
    public void testVerifyUserName() throws Exception {
        //发送请求，并获取返回值（会执行action方法中的代码，包括输出语句）
        mockMvc.perform(MockMvcRequestBuilders.get("/user/verifyUserName")
                .param("userName", "wang5"));
    }
    @Test
    public void testLogin() throws Exception{
        MvcResult result = mockMvc.perform(MockMvcRequestBuilders.get("/user/login")
                .param("userName", "zhang3").param("password", "1234")).andReturn();
        User user = (User) result.getRequest().getSession().getAttribute("user");
        System.out.println(user);
    }
    @Test
    public void testRegister() throws Exception{
        mockMvc.perform(MockMvcRequestBuilders.get("/user/register")
                .param("userName", "wang5").param("password", "1234"));
    }
}
