The beginXXX method will indeed contain the parameters (executed on the
client side). The testXXX method (executed on the server side) will contain
whatever you wish to assert there.

I believe the confusion comes from the fact that you consider Cactus a
functional testing framework whereas it is not. It is a unit testing
framework. For functional tests you should use HttpUnit, HtmlUnit or any of
these functional testing frameworks.

Imagin your servlet is written like this:

public class MyServlet...
{
   public void doGet(...)
   {
      callMethod1(...);
      callMethod2(...);
      callMethod3(...);
   }

   public ... callMethod1(...)
   {
      ...
   }

   public ... callMethod2(...)
   {
      ...
   }

   public ... callMethod3(...)
   {
      ...
   }
}

Cactus will allow you to unit test callMethodX() methods separately (exactly
in the same way you use a JUnit test).

For examples of tests please see
http://jakarta.apache.org/cactus/writing/howto_testcase.html, step 5.

You can also check the sample servlet application which is bundled in the
Cactus distribution.
