Struts2单元测试

现在的struts2 版比 struts1  测试显的更简单了,我们只需引入struts-junit.jar插件和spring的一些架包即可进行测试.下面的这些架包是必需的(以struts2.1.8.1版为例):

struts2-core-2.1.8.1.jar

xwork-core-2.1.6.jar

freemarker-2.3.15.jar

struts2-junit-plugin-2.1.8.1.jar

commons-logging-1.0.4.jar

commons-fileupload-1.2.1.jar

junit-4.8.2.jar

spring-test-2.5.6.jar

spring-core-2.5.6.jar(如果你还想使用Spring的其他功能,直接引入独立包spring.jar就行了)

以上都是必需的,不过特别要注意的是在不用spring当JavaBean工厂的时候,千万别加入struts2-spring-plugin-2.1.8.1.jar 这个架包,要不然你运行测试程序时它死活不让你通过,就在控制台一直提醒你未配置spring监听.

下面写些例子来说明怎么测试struts2:

被测试的Action:

public class MyAction extends ActionSupport implements ServletResponseAware{

	private String name;
	
	private HttpServletResponse response;

	@Override
	public String execute() throws Exception {
		response.setContentType("text/html; charset=utf-8");
		response.getWriter().write("Hello world!");
		response.getWriter().flush();
		return SUCCESS;
	}
	
	public String hello() throws Exception {
		//...
		return "hello";
	}

	@Override
	public void setServletResponse(HttpServletResponse arg0) {
		this.response = arg0;
	}
	 //name's getter and setter
}

测试类:

public class MyActionTest extends StrutsTestCase {
	//测试Action配置文件是否正确
	public void testGetActionMapping() {
        ActionMapping mapping = getActionMapping("/test");
        assertNotNull(mapping);
        assertEquals("/", mapping.getNamespace());
        assertEquals("test", mapping.getName());
    }
	//测试Action代理
	public void testGetActionProxy() throws Exception {
        //set parameters before calling getActionProxy
        request.setParameter("name", "Chase");
        
        ActionProxy proxy = getActionProxy("/test");
        assertNotNull(proxy);

        MyAction action = (MyAction) proxy.getAction();
        assertNotNull(action);

        String result = proxy.execute();
        assertEquals(ActionSupport.SUCCESS, result);
        assertEquals("Chase", action.getName());
    }
	
	//测试重写的execute()方法
	public void testExecuteAction() throws ServletException, UnsupportedEncodingException {
        String output = executeAction("/test");
        assertEquals("Hello world!", output);
    }
	
	//测试自定义方法
	public void testMyMethod() throws Exception {
		ActionProxy proxy = getActionProxy("/helloAction");
        assertNotNull(proxy);

        MyAction action = (MyAction) proxy.getAction();
        assertNotNull(action);

        String result = proxy.execute();
        assertEquals("hello", result);
	}

	//测试value stack
	public void testGetValueFromStack() throws ServletException, UnsupportedEncodingException {
        request.setParameter("name", "Chase");
        executeAction("/test");
        String name = (String) findValueAfterExecute("name");
        assertEquals("Chase", name);
    }
}

struts.xml部分:

<package name="testPackage" extends="struts-default" namespace="/">
	<action name="test" class="com.chase.action.MyAction">
		<result>/test-success.jsp</result>
	</action>
	<action name="*Action" class="com.chase.action.MyAction" method="{1}">
		<result name="{1}">/test-success.jsp</result>
	</action>
</package>
