这篇文章主要内容是使用junit对struts2的action进行测试。
必须的包:
spring-core-2.5.6.jar
spring-test-2.5.6.jar
struts2-junit-plugin-2.2.1.1.jar
注:测试action ,需用到spring。
主要的测试方法:
测试用例需继承 StrutsTestCase
重写setupBeforeInitDispatcher方法,相当与Beforeclass
方法 | 描叙 |
executeAction(String) | 根据action的URL链接,输出action的结果流数据(结果类型不是SUCCESS,可以是FreeMarker, velocity, JSP等) |
getActionProxy(String) | 生成一个action的代理 |
injectStrutsDependencies(object) | 注入一个依赖对象 |
getActionMapping(String) | 获得ActionMapping |
findValueAfterExecute(String) | action执行之后,从值栈中取值 |
属性 | 描叙 |
MockHttpServletRequest request | requset传递给struts2 |
MockHttpServletResponse response | 用于测试struts2输出 |
MockServletContext servletContex | The servlet context 传递给struts2 |
用例:
public class TestAction extends ActionSupport { private String name; public String getName() { return name; } public void setName(String name) { this.name = name; } }
