spring mvc test by mock

我们在写spring mvc controller时，一般情况下都是在浏览器测试

但是有时候，我们写的controller提供的是api接口，这时我们该怎么测试呢？

这时 spring mvc 给我们提供了一个很好的测试方法，mock test

多的不说了，直接看代码：

import static org.springframework.test.web.servlet.request.MockMvcRequestBuilders.*;import static org.springframework.test.web.servlet.result.MockMvcResultHandlers.*;import static org.springframework.test.web.servlet.result.MockMvcResultMatchers.*;import static org.springframework.test.web.servlet.setup.MockMvcBuilders.*;import java.util.Date;import javax.annotation.Resource;import org.junit.Before;import org.junit.Test;import org.junit.runner.RunWith;import org.test.BasicRespMessage;import org.test.controller.TestController;import org.springframework.mock.web.MockHttpServletRequest;import org.springframework.mock.web.MockHttpServletResponse;import org.springframework.test.annotation.Rollback;import org.springframework.test.context.ContextConfiguration;import org.springframework.test.context.junit4.AbstractTransactionalJUnit4SpringContextTests;import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;import org.springframework.test.context.web.WebAppConfiguration;import org.springframework.test.web.servlet.MockMvc;import org.springframework.web.context.WebApplicationContext;@ContextConfiguration(locations = { "classpath*:spring/app-config.xml", "classpath*:spring/mvc-config.xml" })@WebAppConfiguration@RunWith(SpringJUnit4ClassRunner.class)public class TestController extends AbstractTransactionalJUnit4SpringContextTests {    @Resource    private WebApplicationContext wac;    private MockMvc mockMvc;    @Before    public void setup() {        this.mockMvc = webAppContextSetup(this.wac).build();    }    @Test    @Rollback(false)    public void test0() throws Exception {        TestController controller = (TestController) this.applicationContext.getBean("testController");        MockHttpServletRequest request = new MockHttpServletRequest();        MockHttpServletResponse response = new MockHttpServletResponse();        request.setMethod("POST");        request.addParameter("subject", "数学");        request.addParameter("grade", "66"); // 六年级        request.addParameter("time", new Date().getTime() + "");        request.addParameter("sign", new Date().getTime() + "");        BasicRespMessage m = controller.test0(request, response);        System.out.println("--------->" + m.getStatusCode() + "<===>" + m.getStatusDesc() + "<===>" + m.getBody());    }    @Test    public void test1() throws Exception {        this.mockMvc.perform(//                put("/test/test0")//                        .param("subject", "数学") //                        .param("grade", "66") // // 六年级                        .param("time", new Date().getTime() + "") //                        .param("sign", new Date().getTime() + "")) //                .andExpect(status().isOk())//                .andDo(print())                .andReturn();    }}

test0 method 是直接调用controller的method

test1 method 是请求url地址
