怎样将eclipse与Cactus集成，做Container内的单元测试？

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

================================================================================

<!-- config for cactus  -->

      <param-name>param</param-name>

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;
    }
}
