Hi, Iam writing Junit test case for Struts application using cactus and iam using dynavalidator form and have written test case given below public void testSuccessfulLogin() { setRequestPathInfo("/login"); addRequestParameter("userId","bhanu"); actionPerform(); verifyForward("success"); verifyForwardPath("/messages.jsp"); assertEquals("bhanu",getSession().getAttribute("User ID")); verifyNoActionErrors(); } and in the test case if iam using addRequestParameter("userId","bhanu"); the Dynvalidator form is not getting populated i.e if iam retrieving value using getSession().getAttribute("User ID") iam getting null but if am writing a nomal loginform and using it instead of dynavalidator form the loginform is getting populated and iam able to retrive value using getSession().getAttribute("User ID") Please tell me how to write testcases in struts when DynaValidator form is used Thanks and Regards Bhanuprakash The information contained in this electronic message and any attachments to this message are intended for the exclusive use of the addressee(s) and may contain proprietary, confidential or privileged information.
