UFT : Functional, regression, and service testing are the most common uses for the tool. UFT allows testers to automate user behaviours on a web or client-based computer application, as well as test and uncover defects that may arise as a result of such actions. This holds true for the identical operations performed on different people, data sets, Windows operating systems, and browsers. Automation with QTP/UFT, if properly planned and executed, can save a lot of time and money.
Selenium : Selenium is an open-source umbrella project providing a collection of web browser automation technologies and libraries. Without having to learn a test scripting language, Selenium provides a playback tool for building functional tests (Selenium IDE). It also includes a test domain-specific language (Selenese) for writing tests in JavaScript (Node.js), C#, Groovy, Java, Perl, PHP, Python, Ruby, and Scala. Most recent web browsers can then be used to run the tests. Selenium is available for Windows, Linux, and Mac OS X. It's free software distributed under the Apache License 2.0.
