Cactus容器测试入门

此文参考: http://jakarta.apache.org/cactus/integration/howto_tomcat.html

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　：

  </testcase>
  </testsuite>
  </testsuites>

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:
