On Proposing a Test Oracle Generator Based on Static and Dynamic Source Code Analysis

Abstract

Test oracles have become a welcoming approach as a very efficient support for testing any type of application. Since oracle's generation can be a very laborious work, several techniques have been studied in order to perform an automatic or semi-automatic generation. However, the construction of an automated test oracle is not a trivial task, especially in terms of the inference of verdicts and detecting defects. Therefore, this research proposes a strategy to construct an automated test oracle based only on a model generated from reverse engineering, and to detect defects by a combination of static and dynamic source code analysis with a minimum manual labor from testers. We have applied our methodology to some interesting case studies and compared with other tools in order to show usefulness of our approach.
