TESTIMONIALS

I was excited to find the Ext Scheduler plugin for Ext JS. I was even more pleased when I realized the quality of the code. It really helped me to quickly build prototypes and ultimately to rapidly deliver new functionality that our users really liked. This is a great addition for anybody that wants to show schedule data or resource allocation data!

We have been waiting a long time for a testing tool suitable for applications built with JavaScript centric libraries such as Ext JS. Using Siesta, we are able to write both simple and complex tests helping us assure that the quality of our releases remain high. Thanks guys for providing a superb tool!
