D45 Model-based testing

Overview

Model-based testing (MBT) is an approach from software engineering that uses formal models as basis for automatic generation of test cases. A test case is defined as a sequence of actions (or events, or triggers) together with corresponding test data that can be executed against a System Under Test (SUT). In DEPLOY, we investigated a version of MBT using Event-B models as test models, i.e. basis for test generation. The main purpose of MBT track in DEPLOY was to provide the deployment partners an MBT method together with a Rodin plug-in that allows generation of test cases satisfying different coverage criteria (e.g. covering of all events in a model or covering paths to a set of target global states). This includes the generation of appropriate test data that satisfies the guards of the single test steps.

The partners involved in MBT for Event-B were University of Pitesti and University of Dusseldorf on the academic side and SAP on the deployment partners side.

TODO An overview of the work done about Model-based testing. In the last year of DEPLOY, the work done on MBT proceeded according to the plan (the plan was summarized in the previous similar deliverable D32). Moreover, new ideas involving a technique called "automata learning" was investigated. All the theoretical methods were implemented, released as a public Rodin plugin, and tested on the Event-B models available in the DEPLOY model repositories.
