spring 4.0 JUnit简单的Controller测试

比Dao和Service的测试稍微复杂一点。还是先写一个BasicWebTest用来总体配置：

@WebAppConfiguration
@ContextConfiguration(locations= {"classpath:spring/applicationContext.xml","classpath:spring/spring-servlet.xml"})
public class BasicWebTest extends AbstractTransactionalJUnit4SpringContextTests {

    @Autowired
    protected WebApplicationContext wac;

    protected MockMvc mvc;

    @Before
    public void setUp() {
        this.mvc=MockMvcBuilders.webAppContextSetup(wac).build();
    }
}

BasicWebTest 上面多了个 @WebAppConfiguration 注解，并且类中也多了一些方法、字段。直接复制吧。
测试用例如下：

package com.suyin.controller;

import java.util.List;

import org.hamcrest.Description;
import org.hamcrest.Matcher;
import org.junit.Test;
import org.springframework.mock.web.MockHttpServletRequest;
import org.springframework.mock.web.MockHttpServletResponse;
import org.springframework.test.web.servlet.MvcResult;
import org.springframework.test.web.servlet.request.MockMvcRequestBuilders;
import org.springframework.test.web.servlet.result.MockMvcResultMatchers;

import com.jayway.jsonpath.JsonPath;
import com.suyin.BasicWebTest;
import com.suyin.pojo.People;
@SuppressWarnings("unchecked")
public class PeopleControllerTest extends BasicWebTest {

    @Test
    public void queryAll() throws Exception {
        mvc.perform(MockMvcRequestBuilders.get("/people/queryAll"))
                .andExpect(MockMvcResultMatchers.status().isOk())
                .andExpect(MockMvcResultMatchers.view().name("people/list"))
                .andExpect(MockMvcResultMatchers.request().attribute("list", new MatcherAdapter() {

                    @Override
                    public void describeMismatch(Object item, Description mismatchDescription) {
                        mismatchDescription.appendText("wrong list size");
                    }

                    @Override
                    public boolean matches(Object item) {
                        List<People> list=(List<People>) item;
                        return list.size()==;
                    }

                }));
    }
    @Test
    public void asynQueryAll() throws Exception {
        MvcResult mr=mvc.perform(MockMvcRequestBuilders.get("/people/asynQueryAll").content("{\"id\":1}"))
                .andExpect(MockMvcResultMatchers.status().isOk())
                .andExpect(MockMvcResultMatchers.jsonPath("$.id").exists())
                .andReturn();

        MockHttpServletResponse response=mr.getResponse();
        MockHttpServletRequest request=mr.getRequest();
    }

    @Test
    public void update1() throws Exception {
        mvc.perform(MockMvcRequestBuilders.post("/people/update").param("id", "")
                .param("name", "Jack")
                .param("address", "japan")
                .param("age", ""))
                .andExpect(MockMvcResultMatchers.status().isOk())
                .andExpect(MockMvcResultMatchers.view().name("people/detail"));

    }
    @Test
    public void update2() throws Exception {

        mvc.perform(MockMvcRequestBuilders.post("/people/update")
                //.param("name", "Jack")
                .param("address", "japan")
                .param("age", ""))
                .andExpect(MockMvcResultMatchers.status().isOk())
                .andExpect(MockMvcResultMatchers.view().name("error"));
    }

    @Test
    public void add1()throws Exception  {
        mvc.perform(MockMvcRequestBuilders.post("/people/add")
                .param("name", "JJJJ")
                .param("address", "")
                .param("age", "")
                )
                .andExpect(MockMvcResultMatchers.status().isOk())
                .andExpect(MockMvcResultMatchers.view().name("people/detail"));
    }
    @Test
    public void add2()throws Exception  {
        mvc.perform(MockMvcRequestBuilders.post("/people/add")
                .param("address", "")
                .param("age", "")
                )
                .andExpect(MockMvcResultMatchers.status().isOk())
                .andExpect(MockMvcResultMatchers.view().name("error"));
    }

    abstract class MatcherAdapter<T> implements Matcher<T>{

        @Override
        public void describeTo(Description arg0) {
            // TODO Auto-generated method stub

        }

        @Override
        public void _dont_implement_Matcher___instead_extend_BaseMatcher_() {
            // TODO Auto-generated method stub

        }

        @Override
        public abstract void describeMismatch(Object item,
                Description mismatchDescription);

        @Override
        public abstract boolean matches(Object item) ;

    }
}

认真说来关于Controller的Spring测试就这样了。在多就是关于MockMvc的API学习了。
