Geração de objetivos de teste de sistemas reativos baseada na técnica de verificação de modelos CTL.

Abstract

Techniques and tools for model based testing have been developed to make the process of testing distributed concurrent reactive systems more efficient and rigorous. The inherent nondeterminism of these systems can make it difficult to test them due to the complex process of obtaining test cases configurations from models. To better guide the testing process, properties specified to these systems are used as basis for the test case generation. Such properties, called test purposes, shall be exhibitedby the implementation under test through test case execution. However, specifying test purposes from the common complex and large models of these systems suffers from the lack of appropriated tools and techniques, making it error-prone and inadequate. Thus, test cases based on such test purposes may be affected, getting no desirable soundness. Aiming at solving this problem, we present a technique for test purpose generation for reactive systems based on the CTL model checking technique. We aim at taking benefit from the efficiency of model checking algorithms to better analyze the models to generate the test purposes.
