SpringMVC学习--10 测试

TDD（Test Drive Development）测试驱动开发技术概念，从需求出发设计一个预期结果的测试用例，通过不断地编码和重构，使得用例通过测试，从而保证代码的质量和可控性。

示例：对Controller进行测试，通过返回结果评价Controller的设计

1. jsp页

page.jsp：

<%@ page language="java" contentType="text/html; charset=UTF-8"
    pageEncoding="UTF-8"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>Test Page</title>
</head>
<body>
    <pre>
        Welcome to Spring MVC world.
    </pre>
</body>
</html>

2. 普通Bean

DemoService:

package com.service;

import org.springframework.stereotype.Service;

@Service
public class DemoService {
    public String saySomething() {
        return "hello";
    }
}

3. Controller和RestController

DemoNormalController:

package com.controller;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;

import com.service.DemoService;

@Controller
public class DemoNormalController {
    @Autowired
    DemoService demoService;

    @RequestMapping(value="/testNormal")
    public String testNormal(Model model) {
        model.addAttribute("msg", demoService.saySomething()); 
        return "page";
    }
}

DemoMyRestController:

package com.controller;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

import com.service.DemoService;

@RestController
public class DemoMyRestController {
    @Autowired
    DemoService demoService;

    @RequestMapping(value="/testRest", produces="text/plain; charset=UTF-8")
    public String testRest() {
        return demoService.saySomething(); 
    }
}

4. Test类

TestControllerIntegrationTests:

package com.mock;

import static org.springframework.test.web.servlet.request.MockMvcRequestBuilders.get;
import static org.springframework.test.web.servlet.result.MockMvcResultMatchers.content;
import static org.springframework.test.web.servlet.result.MockMvcResultMatchers.forwardedUrl;
import static org.springframework.test.web.servlet.result.MockMvcResultMatchers.model;
import static org.springframework.test.web.servlet.result.MockMvcResultMatchers.status;
import static org.springframework.test.web.servlet.result.MockMvcResultMatchers.view;

import org.junit.Before;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.http.MediaType;
import org.springframework.mock.web.MockHttpServletRequest;
import org.springframework.mock.web.MockHttpSession;
import org.springframework.test.context.ContextConfiguration;
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;
import org.springframework.test.context.web.WebAppConfiguration;
import org.springframework.test.web.servlet.MockMvc;
import org.springframework.test.web.servlet.setup.MockMvcBuilders;
import org.springframework.web.context.WebApplicationContext;

import com.config.MvcConfig;
import com.service.DemoService;

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(classes = {MvcConfig.class})
// This annotation indicates that ApplicationContext which 
// is loaded by this annotated class should be WebApplicationContext.
// This annotation has a default resource path(i.e. "src/main/webapps") for test to web application root in maven,
// but in spring MVC, this path should be overridden by "src/main/resources".
@WebAppConfiguration("src/main/resources")
public class TestControllerIntegrationTests {
    private MockMvc mockMvc; // main entry point for server-side Spring MVC test support

    @Autowired
    private DemoService demoService;

    @Autowired
    WebApplicationContext wac;

    @Autowired
    MockHttpSession session; // unused

    @Autowired
    MockHttpServletRequest request; // unused

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

    @Test
    public void testNormalController() throws Exception {
        this.mockMvc.perform(get("/testNormal")) //模拟测试请求
                    .andExpect(status().isOk()) // 预期返回状态为200
                    .andExpect(view().name("page")) // 预期view名为page
                    .andExpect(forwardedUrl("/WEB-INF/classes/views/page.jsp")) //预期request的url
                    .andExpect(model().attribute("msg", demoService.saySomething())); //预期model的msg属性为“hello”
    }

    @Test
    public void testRestController() throws Exception {
        this.mockMvc.perform(get("/testRest"))
                    .andExpect(status().isOk())
        .andExpect(content().contentType("text/plain; charset=UTF-8"))
            .andExpect(content().string(demoService.saySomething()));
    }
}
