Avignon

Avignon is an acceptance test system that allows you to write executable tests in a language that you define. Avignon tests are written in XML and executed by a JUnit test runner using small pieces of Java code associated to each XML tag.  It comes with a number of tags already coded that allow fairly effective testing of web applications and limited testing of Java Swing and AWT based applications, but you can derive the most benefit from it by using its extensibility to create your own testing language that best expresses your tests. For programming teams that use the eXtreme Programming (XP) methodology, Avignon lets customers express acceptance tests in a non-ambiguous manner before development starts.
