My company Antalika develops big portals and auction websites (Groupon clones) for belorussian and international clients. For big portals we developed our company also do the maintaining. For stable development and good regression testing we start use XML2Selenium since January 2013.
Web Developers in our company working with XML2Selenium are not Java developers and have no experience for automated testing. In the beginning some small problems happened but now the creating of tests is very quick and I like this product. In future we will use it more. Dima and his team provide great support and fix bugs very quickly.
