Re: AJAX Testing

Hi Frank,

I looked briefly at P2T a while back but didn't want to use a scripting
language to write the tests. We've used selenium on multiple projects for
the last four years, and while it does have several drawbacks (most notibly
speed and test maintenance), we've been able to work round them. Selenium's
killer feature for me is that it requires very little technical ability to
read the tests and if you're using the firefox plugin doesn't even look like
source code. This means that we can walk through the tests with our QA's and
customers, without turning them off with a java IDE environment or a
programming language. We've recently started incorporating jbehave and some
funky mods to the selenium code which allows us to write tests like...

<!-- Test login -->
open | the nuke data page
setup | a customer account with id 1AAA123 | fred
open | the login page
type | into the username text box | ${fred.username}
type | into the password text box | ${fred.password}
clickAndWait | the login button
assertLocation | */customer/1AAA123
assertTextPresent | Hello ${fred.firstName}

We've managed to get the build time down to an acceptable amount by farming
the tests out to multiple VMs.
For ajax testing we tend to use waitForXXX (although this does have the
drawback of waiting a number of seconds if the ajax request fails). We also
have a custom action waitForAjaxResponse which works with with prototype.js
We have used selenium to perform system monitoring - a small suite hooked
into the CI server, but no satisfactory solution for load testing as yet.
We're tried jmeter and httpunit and are currently exploring a DSL solution
in groovy / grails. If it looks like a dead end I'll give P2T another look.

Kind regards,

Steve
