GraphWalker is a open source Model-based testing tool for test automation. It's designed to make it easy to design your tests using graphs.


GraphWalker is a Model-Based testing tool. It reads models in the shape of directed graphs, and generate [test] paths from these graphs.

A model can look like the one to the next. The model is collection of arrows and nodes and together they create a graph.


  • An arrow represents an action.
  • A node represents a verification.

What GraphWalker does

Given a model and a generator rule, GraphWalker by mathematical algorithms generates a path which corresponds to your test idea. Next image illustrate such result.


Then this path would be provided to the tool of your choice to execute the test.
In another words GraphWalker is a test generation tool.
