Cactus容器测试入门

我们在web.xml中的webapp之间加入:

< servlet >
   < servlet-name > ServletRedirector </ servlet-name >
   < servlet-class > org.apache.cactus.server.ServletTestRedirector </ servlet-class >
   < init-param >
     < param-name > param1 </ param-name >
     < param-value > value1 used for testing </ param-value >
   </ init-param >
</ servlet >

< servlet >
   < servlet-name > ServletTestRunner </ servlet-name >
   < servlet-class > org.apache.cactus.server.runner.ServletTestRunner </ servlet-class >
</ servlet >

加入mapping:

< servlet-mapping >
     < servlet-name > ServletRedirector </ servlet-name >
     < url-pattern > /ServletRedirector </ url-pattern >
</ servlet-mapping >

< servlet-mapping >
     < servlet-name > ServletTestRunner </ servlet-name >
     < url-pattern > /ServletTestRunner </ url-pattern >
</ servlet-mapping >

然后我们写一个简单的Servlet来进行测试:

import  javax.servlet.http.HttpServlet;
import  javax.servlet.http.HttpServletRequest;

public   class  SampleServlet  extends  HttpServlet
{
    public void saveToSession(HttpServletRequest request)
    {
        String testparam = request.getParameter("testparam");
        request.getSession().setAttribute("testAttribute", testparam);
    }
}

对于此Servlet在xml的配置我就不写了．想必你也了然于心了吧．

来看看我们的测试类:

import  junit.framework.Test;
import  junit.framework.TestSuite;

import  org.apache.cactus.ServletTestCase;
import  org.apache.cactus.WebRequest;

public   class  TestSampleServlet  extends  ServletTestCase
{
    public TestSampleServlet(String theName)
    {
        super(theName);
    }

    public static Test suite()
    {
        return new TestSuite(TestSampleServlet.class);
    }

    public void beginSaveToSessionOK(WebRequest webRequest)
    {
        webRequest.addParameter("testparam", "it works!");
    }

    public void testSaveToSessionOK()
    {
        SampleServlet servlet = new SampleServlet();
        servlet.saveToSession(request);
        assertEquals("it works!", session.getAttribute("testAttribute"));
    }
}

部署之后，启动Tomcat,访问:

http://localhost:8080/test/ServletTestRunner?suite=TestSampleServlet
这时候你会看到输出　：

看来程序没有大问题，已经正确执行．不过这时提示有一个类找不到．
对于这个问题我们可以去http://commons.apache.org/downloads/download_codec.cgi下载．

这个xml看起来多少不习惯．我们可以下载xsl把它转换成html格式．
点此下载 把它放到你web应用的根目录下．

这个时候你可以访问如下地址：
http://localhost:8080/test/ServletTestRunner?suite=TestSampleServlet&xsl=cactus-report.xsl

这时候你就会看到友好的Html格式了:
