使用HttpUnit进行集成测试

//创建Servlet的运行环境
ServletRunner sr = new ServletRunner();
//向环境中注册Servlet
sr.registerServlet( "InternalServlet", InternalServlet.class.getName() );
//创建访问Servlet的客户端
ServletUnitClient sc = sr.newClient();
//发送请求
WebRequest request = new GetMethodWebRequest( " http://localhost/InternalServlet " );
request.setParameter("pwd","pwd");
//获得该请求的上下文环境
InvocationContext ic = sc.newInvocation( request );

//调用Servlet的非服务方法
InternalServlet is = (InternalServlet)ic.getServlet();
is.myMethod();

//直接通过上下文获得request对象
System.out.println("request中获取的内容："+ic.getRequest().getParameter("pwd"));

//直接通过上下文获得response对象,并且向客户端输出信息
ic.getResponse().getWriter().write("haha");

//直接通过上下文获得session对象，控制session对象
//给session赋值
ic.getRequest().getSession().setAttribute("username","timeson");
//获取session的值
System.out.println("session中的值："+ic.getRequest().getSession().getAttribute(
"username"));

//使用客户端获取返回信息，并且打印出来
WebResponse response = ic.getServletResponse();
System.out.println(response.getText());
