Development phase

The specified examples guide the implementation work

Automation of the examples can be done in parallel with feature implementation

The whole team is responsible on automation In the end, all the automated examples pass

when run against the implementation

Deliver phase

Implemented features are demonstrated to all stakeholders

Original examples are executed against the produced software

Feedback serves as input to the next discussion phase

Robot Framework

Generic test automation framework Utilizes the keyword-driven testing approach Suitable both for "normal" automation and ATDD

Implemented with Python Runs also on Jython (JVM) and IronPython (.NET)
