AFAIK, the getURL() method returns a simulated URL
which is specified by WebRequest#setURL method.
So, you cannot know a forwarded URL by using the method.

If you are interested in the servlet logic, you might separate
the logic into some methods to make your test easier. For your case:
- a method returns String as a resource name to be forwarded
- a method forward the request to the selected resource
For example, the code will be like as follows:
public String getForwardTo() {
// resource selection logic
return resourceName;
}
...
req.getRequestDispatcher(getForwardTo()).forward(req, res);
You can write tests for the getForwardTo() method to verify
the selection has been done properly.
If you want the forward is been done properly,
you have to verify the resulting HTML in endXXX().
To make it easier, you might insert ID string as a HTML comment
in every JSPs.
Hope this helps,
