Robot Framework is a generic open source test automation framework for acceptance testing and acceptance test-driven development (ATDD). It has easy-to-use tabular test data syntax and it utilizes the keyword-driven testing approach. Its testing capabilities can be extended by test libraries implemented either with Python or Java, and users can create new higher-level keywords from existing ones using the same syntax that is used for creating test cases. Robot Framework is operating system and application independent. The core framework is implemented using Python, supports both Python 2 and Python 3, and runs also on Jython (JVM), IronPython (.NET) and PyPy. The framework has a rich ecosystem around it consisting of various generic test libraries and tools that are developed as separate projects. For more information about Robot Framework and the ecosystem, see http://robotframework.org. Robot Framework project is hosted on GitHub where you can find source code, an issue tracker, and some further documentation. See CONTRIBUTING.rst if you are interested to contribute. Downloads are hosted on PyPI, except for the standalone JAR distribution that is on Maven central. Robot Framework development is sponsored by Robot Framework Foundation.
