GraphWalker

GraphWalker is an open source model-based testing tool. Models of the system under test are drawn as directed graphs in GraphWalker Studio; GraphWalker generates test paths through the models according to generators and stop conditions, offline or online, and drives the test code that implements each vertex and edge.

GraphWalker can be used from the command line or as a Maven dependency in Java projects; the latest stable version is 4.3.3.
