Ontology Based Test Case Generation for Black Box Testing

Abstract

Software systems are not considered complete unless properly tested and verified. In existing literature, a growing interest on establishment of automated testing techniques has been observed. However, tedious manual process of test case generation largely depends upon domain knowledge and formalized representation of user requirements. The advent of semantic web engineering has led the foundation for developing ontologies as a mean to express information and knowledge semantics regarding particular domain efficiently. In software testing, ontologies can be significantly helpful to automate testing phase as they encode domain knowledge in machine interpretable format. We have proposed automatic test case generation framework that involves ontology-based requirement specification and learning based methods for conducting black box testing. Our approach integrates knowledge-based system (ontology) with learning-based testing algorithm to automate: generation of test cases, test execution and test verdict construction. Proposed framework includes, requirement ontology to formalize requirement specification, Dialogue Manager that enables selection of available test cases and Learning Based Testing to generate counter examples of test cases through system learning. The contribution of this paper is to enable 1) requirement elicitation and specification using ontologies 2) test data selection from existing ontologies and 3) automatic test case generation from existing test cases. To represent the applicability of this research, ontology for requirement elicitation and specification is developed. Framework proposed in this research paper is an effort to provide software testing tools to save time, cost and efforts during test design phase.
