JUNIT -- springMVC的action进行单元测试

原文：http://blog.csdn.net/gaopeng0071/article/details/49946575

我开发环境springMVC版本3.0.4

样例代码：

package com.redhorse.agent.action.junit;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

import org.junit.Assert;
import org.junit.BeforeClass;
import org.junit.Test;
import org.springframework.mock.web.MockHttpServletRequest;
import org.springframework.mock.web.MockHttpServletResponse;
import org.springframework.mock.web.MockServletContext;
import org.springframework.web.context.WebApplicationContext;
import org.springframework.web.context.support.XmlWebApplicationContext;
import org.springframework.web.servlet.HandlerAdapter;
import org.springframework.web.servlet.HandlerExecutionChain;
import org.springframework.web.servlet.HandlerMapping;
import org.springframework.web.servlet.ModelAndView;
import org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter;
import org.springframework.web.servlet.mvc.annotation.DefaultAnnotationHandlerMapping;

import com.redhorse.bean.AgentEmployeeBean;

public class EmployeeManagerActionTest {
    private static HandlerMapping handlerMapping;
    private static HandlerAdapter handlerAdapter;

    /**
     * 读取spring3 MVC配置文件
     */
    @BeforeClass
    public static void setUp() {
        if (handlerMapping == null) {
            String[] configs = { "file:src/spring/*.xml","file:src/spring/servlet/*.xml" };
            XmlWebApplicationContext context = new XmlWebApplicationContext();
            context.setConfigLocations(configs);
            MockServletContext msc = new MockServletContext();
            context.setServletContext(msc);
            context.refresh();
            msc.setAttribute(WebApplicationContext.ROOT_WEB_APPLICATION_CONTEXT_ATTRIBUTE, context);
            handlerMapping = (HandlerMapping) context.getBean(DefaultAnnotationHandlerMapping.class);
            handlerAdapter = (HandlerAdapter) context
                    .getBean(context.getBeanNamesForType(AnnotationMethodHandlerAdapter.class)[0]);
        }
    }

    /**
     * 执行request对象请求的action
     *
     * @param request
     * @param response
     * @return
     * @throws Exception
     */
    public ModelAndView excuteAction(HttpServletRequest request, HttpServletResponse response) throws Exception {
        HandlerExecutionChain chain = handlerMapping.getHandler(request);
        final ModelAndView model = handlerAdapter.handle(request, response, chain.getHandler());
        return model;
    }

    @Test
    public void save() throws Exception {
        MockHttpServletRequest request = new MockHttpServletRequest();
        MockHttpServletResponse response = new MockHttpServletResponse();
        AgentEmployeeBean ae = new AgentEmployeeBean();
        ae.setId(12);
        request.getSession().setAttribute("curUser", ae);
        request.setRequestURI("/employee/addEmployee");
        request.addParameter("email", "gpqhl0071@126.com");
        request.addParameter("mobile", "15652377458");
        request.addParameter("realName", "gao");
        request.addParameter("subRegionIds", "1");
        request.addParameter("end", "1000");
        request.addParameter("point", "10");
        request.setMethod("POST");
        // 执行URI对应的action
        final ModelAndView mav = this.excuteAction(request, response);
        // Assert logic
        Assert.assertEquals("/employee/addEmployee", mav.getViewName());
        String msg = (String) request.getAttribute("msg");
        System.out.println(msg);
    }

}

需要改动的代码： 
33行，按照自己要读取的spring配置进行修改。 
61到81行，写自己的单元测试方法。
