Model Based Testing with Constraint Logic Programming: First Results and Challenges

We summarize our continuing efforts at model based testing of reactive systems on the grounds of Constraint Logic Programming. First experimental results give rise to optimism w.r.t. scalability of our approach, point at necessary improvements, and they help identify future areas of research. Among others, these include search strategies more powerful than backtracking alone, appropriate (graphical) input languages for test cases, and theoretical aspects such as the relationship between test cases (traces) and system specifications
