Testing Web 2 cat apps

Hi All,
So far all the Catalyst testing I've done has been with WWW::Mechanize.

I'm just writing tests for a Catalyst component I've written that only
produces one TT view, everything else is done with JQuery/AJAX/JSON. It
would be nice to test all the JQuery from the Perl test suite... But how?

If there isn't a good way to do it from the Perl tests, then what is the
strategy for automated testing of JQuery code in Catalyst apps?

Lyle

Selenium + Perl. It executes the tests within a running browser.
Requires Java to run the browser controller (the Selenium server).
There is a sweet IDE plugin for Firefox for writing the tests. Google
around for it. There are many examples, docs, and supporting modules.

I second the recommendation of Selenium. Even with the IDE it can
take a while to get tests together, but it's well worth it IME.

Well worth it, but running selenium tests against IE using DOM
accessors (div[2]/table[2]/tr[1]/td[2]) can be painfully slow. CSS
accessors are recommended for reasonable speed.

If you need to test file upload/downloads, then a daemon based on
Win32::GuiTest is handy to type filenames into browser file dialogs
(can't be done from javascript). I've attached one we use in our
vmware windows selenium snapshot.

Good to know that there's an option for IE + Sel + file uploads. On the
firefox front, it is possible if you get selenium to launch FF right
(google for the particular invocation.) Then you just put a filename in the
box like its a text input, and FF will submit the file for you - all via
javascript.

"CSS accessors are recommended for reasonable speed."

And they tend to be more robust to page layout changes, compared to
XPath.

That doesn’t make any sense. Any CSS selector has a directly
equivalent XPath expression.

Whether XPath is more or less robust depends only on whether
you write it to be.

And this (I don't think Aristotle mentions in his post) is really cool:
