一个cactus测试的例子，用eclipse
另外apache上面的文档关于如何集成到eclipse的部分还没有换。
http://jakarta.apache.org/cactus/integration/eclipse/runner_plugin.html和http://jakarta.apache.org/cactus/integration/eclipse/webapp_plugin.html上面提到的
org.apache.cactus.integration.eclipse_[version]现在在apache上是找不到的。
http://jakarta.apache.org/cactus/integration/manual/howto_config.html给出了应该如何配置的问题。
另，上面的快速入门未看过：
http://jakarta.apache.org/cactus/integration/howto_tomcat.html
下面是转贴的：http://blog.csdn.net/eagle51998/archive/2006/07/10/899550.aspx
注意：如果你只是测试servlet，那么在web.xml中只需要有servlet的相关配置即可。
并且，按照
http://jakarta.apache.org/cactus/integration/manual/howto_config.html，cactus.properties中除了cactus.contextURL 属性，其他都是可选的。
Cactus是apache的一个开源测试框架，它是建立在junit 的基础上，它的功能比junit 强大的多，它可以做服务器端的测试，特别是Container 内的测试，它是一个自动测试框架，经过一段时间的研究，将我的心得写下来供大家参考。
首先需要的资源如下：
1 . Eclipse SDK Version: 3.1.2
2. 需要的类库有：aspectjrt-1.2.1.jar， cactus-1.7.1.jar ，commons-httpclient-2.0.2.jar，commons-digester.jar，httpunit-1.6.jar， junit.jar。
3. 将服务器与eclipse集成（可选，集成进来的主要目的是可以实现debug）
下面是需要编写的文件资源：
1。cactus.properties
################################################################################
# Configuration file for Cactus.
# Each project using Cactus need to have such a file put in the CLASSPATH
# (Meaning the directory containgin this file should be in the CLASSPATH, not
# the file itself of course ... :) )
# Defines the URLs that will be used by Cactus to call it's redirectors
# (Servlet and JSP). You need to specify in these URLs the webapp context
# that you use for your application. In the example below, the context is
# "test".
cactus.servletRedirectorURL = http://localhost:7001/cactus/ServletRedirector
cactus.jspRedirectorURL = http://localhost:7001/cactus/JspRedirector
cactus.filterRedirectorURL = http://localhost:7001/cactus/FilterRedirector
# Name of Cactus property that specify the URL up to the webapp context.
# This is the base URL to call for the redirectors. It is made up of :
# "http://" + serverName + port + "/" + contextName.
# 修改cactus.contextURL值为所在webapp的起始路径
cactus.contextURL = http://localhost:7001/cactus
cactus.servletRedirectorName = ServletRedirector
cactus.jspRedirectorName = JspRedirector
cactus.filterRedirectorName = FilterRedirector
# Name of the Cactus property for defining an initializer (i.e. a class
# that is executed before the Cactus tests start on the client side).
cactus.initializer=
cactus.enableLogging=true
################################################################################
将cactus.properties放在project 的WEB-INF下的Classes 目录下，这样的话，在Weblogic启动的时候就可以直接找到这个配置文件。
2. 在web.xml中添加cactus的测试类，（类似于路由器）发送的请求，经过Web Container进行过滤
web.xml
================================================================================

================================================================================
3. 编写一个测试类
public class TestDelegate extends ServletTestCase
{
private TestDelegate delegate = new TestDelegate ();
public void setUp() throws Exception
{
// begin some initial work
// construct some Context
}
public void testAdd() throws BusinessException
{
Dto dto = new Dto();
delegate .add(dto);
delegate.update(dto);
delegate.delete(dto);
}
}
运行步骤：
启动Weblogic ，确保在Web Container下可以找到ServletRedirector等Servlet
使用Junit 来运行程序，还可以使用Test Suit来执行测试套件
================================================================================
public class TestAll
{
public static Test suite()
{
TestSuite suite = new TestSuite(
"Cactus unit tests for J2EE 1.3");
// Add shared tests
//suite.addTest(TestShareAll.suite());
// Test cases specific to J2EE 1.3 only
suite.addTestSuite(TestHello.class);
suite.addTestSuite(TestWorld.class);
suite.addTestSuite(TestDelegate.class);
suite.addTestSuite(TestEJB.class);
suite.addTestSuite(TestOther.class);
return suite;
}
}
