Manual testing is a time consuming process. In addition, regression testing, because of its repetitive nature, is error-prone, so automation is highly desirable. Robot Framework is simple, yet powerful and easily extensible tool which utilizes the keyword driven testing approach. Easy to use tabular syntax enables creating test cases in a uniform way. Ability to create reusable high-level keywords from existing keyword ensures easy extensibility and reusability. Simple library API, for creating customized test libraries in Python or Java, is available, while command line interface and XML based output files ease integration into existing build infrastructure, for example continuous integration systems. All these features ensure that Robot Framework can be quickly used to automate test cases.
