The emphasis of this article is to introduce the initial idea of Cactus from a developer's point of view. And extend the idea in Struts env. StrutsUT is not a mature product, it is only a reference implementation of the author's idea. Readers can reference StrutsUT to do their own implementation.
I looked through StrutsTestCase user guide. I am not very clear in some points. When the action class uses external interface, StrutsUT can handle it with mock object. I don't know how StrutsTestCase handles it. This point is an important aspect of StrutsUT. If you have time, would you please give out a test case using StrutsTestCase according to the example in my article? Thanks.
