Re: How to assert forwards?
Hi!
Yes, separating the forwarding from the rest is definitely a solution.
Thanks very much for the help Kazuhito and Nicolas!

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.
cactuslist Why ?? It seems a great solution : you can check more ie that
there is
cactuslist no error message in the page code...
cactuslist
cactuslist Well.. in this case I don't want to verify the content of the
resulting
cactuslist page. Only the logic of the servlet. And it could be pretty
difficult to
cactuslist figure out from the resulting HTML which jsp page that actually
has been
cactuslist invoked. (Unless I code some comment into it telling which jsp
page it
cactuslist is.. hmm.. that might be a solution..)
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,

Re: How to assert forwards?
Salut Niklas, 2005/8/11, Niklas Lindholm [EMAIL PROTECTED]: Hi! I am writing a web application that is using an MVC design. This means that at the end of almost every servlet I do a request.getRequestDispatcher(foo.jsp).forward(request, response) I some cases the servlet makes a choice between two (or more) different targets to forward() to. Something like: if(somethingIsTrue) request.getRequestDispatcher(foo.jsp).forward(request, response); else request.getRequestDispatcher(bar.jsp).forward(request, response); Is there a way to make a Cactus test case that asserts that the forward is being done to the correct target? I can't find any way to get information about what forward that has been done. response.getWebRequest().getURL(); (Except trying to find out by looking at the resulting HTML is end(), but that doesn't seem like a good idea..) Why ?? It seems a great solution : you can check more ie that there is no error message in the page code...
