Before boring you much, here is the link on spikedevnews.
I am always big on automation, call my lazy, but I hate doing repetitive jobs! Once firefox came out, and was seeing all these wonderful extensions, the idea of TG4W struck me. All I wanted to do was record all the my actions on the browser, and be able to replay them back.
The idea extended to creating automated scripts (HttpUnit, HTMLUnit, php-simpletest) using the recorded actions for nightly testing. Since my company SpikeSource is big on testing and automation, this was a easy business goal too!
After 1 year of successful deployment, here I am the proud owner of TestGen4Web with more than 30,000 downloads. If you are interested, you can download it from dev.spikesource.com or addons.mozilla.org.
I had a lot of help from some of the developers in Europe, and our inhouse UI guru Keisuke Omi .
