acceptance test driven development using robot framework' by pekka klarch & janne harkonen
DESCRIPTION
Acceptance test driven development (ATDD) is an important agile practice merging requirement gathering with acceptance testing. In its core are concrete examples, created together with the team, that provide collaborative understanding and, as automated acceptance tests, make sure that the features are implemented correctly. There are many ways to create ATDD examples/tests, and the behavior driven development (BDD) style with Given-When-Then format is one of the more popular ones. Robot Framework is an open source test automation framework suitable for ATDD and acceptance testing in general. It has a flexible test data syntax that supports keyword-driven, data-driven, and BDD styles, but is still simple enough so that also non-programmers can create and understand test cases. The simple test library API makes extending the framework easy, and there are several ready made libraries that allow testing generic interfaces such as web, databases, Swing, SWT, Windows GUIs, Flex, and SSH out-of-the-box. This presentation gives an introduction both to ATDD and Robot Framework. It contains different demonstrations and all the material will be freely available after the presentation.TRANSCRIPT

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)
