Text-driven Model-Based Testing Tool 4TEST MBT TOOL A new type of model-based testing tool by which test cases can be generated automatically. No graphical editor is needed. The tool is clearly agile, since the model is an extension of Gherkin language. By applying the tool the test set is optimal, since it's test based model and not development based such as activity or state transition diagrams. The related method is provable better than former methods. The tool generates structured keyword-driven tests which can be exported to different test execution tools.
