Paolo Arcaini (National Institute of Informatics),  
Decomposition-Based Approach for Model-Based Test Generation

Model-based test generation by model checking is a well-known testing

technique that, however, suffers from the state explosion problem of

model checking and it is, therefore, not always applicable. In this

talk, I present an approach that addresses this issue by decomposing a

system model into suitable subsystem models separately analyzable. The

technique consists in decomposing that portion of a system model that

is of interest for a given testing requirement, into a tree of

subsystems by exploiting information on model variable dependency. The

technique generates tests for the whole system model by merging tests

built from those subsystems. Effectiveness and efficiency of the

proposed decomposition-based test generation approach are measured

both in terms of coverage and time.
