way.• Allows using keyword-driven, data-driven and behavior-driven

(BDD) approaches.• Provides easy-to-read reports and logs in HTML format.• Is platform and application independent.• Provides a simple library API for creating customized test libraries.• Implemented with Python.• Provides support for Selenium for web testing.
