The user interface of tellurium is very easy to use,it's also support multiple browsers and platforms so it's really good for me as I'm working in cross browser projects.It has a lot of features like parallel tests,browser automation etc.So i can test my project easily without writing any line of code.The documentation provided by them is not that much understandable but they have their own forum where you can get help from experts who are there with them.Also its free version available which allow us to try all major features before we decide whether to buy or not.I would say if your looking out for something simple then go ahead otherwise pay more money for the advanced versions of this product because it will save your time and efforts while developing high performance solutions.Automation of our application using different browsers & Operating systems.
