Testing web apps in general and qooxdoo apps in particular has been a recurring issue in the community (e.g. see this wiki page and the links provided here).

The new Simulator project aims to facilitate testing of qooxdoo apps through integration with Selenium, a popular, open-source web testing framework. The nice thing about Selenium is that it also lends itself well to automating web pages ("simulations"), hence the name.

The project is still in its early stage, its main contribution being a qooxdoo-specific extension to the Selenium engine. This extension adds commands and so called locators to Selenium that hook into qooxdoo's object system and ease the way a test interacts with qooxdoo. If you are concerned with testing qooxdoo apps, or are already using Selenium for your work, this qooxdoo-contrib contribution might be interesting. Other parts of the project include a small sample application with an interactive Selenium shell and ready-to-run test scripts that can also be used as templates for your own endeavours.
