How to test ?
Hi,
I've recently started using tapestry. Impressive so far.
The only problem I'm having is how to test the page classes. I've
found Howard's AbstractInstantiator which is helpful to get around the
abstract class problem. But I'm unsure how to test validation.
I've been looking Tapestry in Action which is a pretty good read, but
I cannot believe that there are only 2 pages (out of 500+) that
mention testing, and these don't really go into any detail.
Anybody have some examples?
thanks in advance
scott

We've also had problems testing pages as there is so much to mock. Tapestry is
very good to use interfaces which should make it easy to mock, but there
seems to be very much mocking to be done as there is so many interfaces with
so many methods.
We also tried inheriting the pages and test through that, but it proved to be
hard to test, as Tapestry does a lot of setup work runtime when a request
comes in. Naturally, that is one of the reasons we like Tapestry, that it
does all this for us at submit. But it also makes it quite hard to unit test.
Instead, we started using jwebunit (http://jwebunit.sourceforge.net/) to test
the pages as a webclient. This is a different kind of testing, as it tests
real functionality and integration instead of the unit testing of pages. But
it works quite well.

Very much so! We've also tried the AbstractInstantiator, but it really does'nt
help us that much.
A nice thing would be to have a real unit testing helper class, which
fakes/mocks some of all the processing that Tapestry performs at submit. A
little like StrutsTestCase (http://strutstestcase.sourceforge.net/) do for
struts. It can fake input parameters, URLs etc. to make it look like a submit
was performed.
I guess this would require calling code deep inside Tapestry; the code that
actually does all the plumbing when a submit occurs into Tapestry at runtime.
I do not know if this can be easily reused in such a testcase. Anyone here
fluid enough in the Tapestry sources to give a clue about if this can be
done? This should be based in the 3.1 sources should it not?

I have been waiting a bit before replying, just to see if anybody else had
any comments.
I, too, am very interested in this topic. Does anybody have any practical
examples that they could show? Or, is there a detailed wiki page or
something that could help me get started with Tapestry testing?
Are there others on the list who are also interested in this topic?
Cheers,
David

Hi Scott,
As for the page components I have created and inner class to extend the page
object and then used that for testing.
The other part of the testing has been using was using httpUnit to automate
movements around the application while it is running. This can be a bit
finicky at times but it also has been a good indicator of bugs.
Cheers,
Daniel
