This book reviews the state-of-the-art in combinatorial testing, with particular emphasis on the automatic generation of test data. It describes the most commonly used approaches in this area - including algebraic construction, greedy methods, evolutionary computation, constraint solving and optimization - and explains major algorithms with examples. In addition, the book lists a number of test generation tools, as well as benchmarks and applications. Addressing a multidisciplinary topic, it will be of particular interest to researchers and professionals in the areas of software testing, combinatorics, constraint solving and evolutionary computation.
Combinatorial testing of software analyzes interactions among variables using a very small number of tests. This advanced approach has demonstrated success in providing strong, low-cost testing in real-world situations. Introduction to Combinatorial Testing presents a complete self-contained tutorial on advanced combinatorial testing methods for re
Combinatorial testing (CT) has been shown to be a very effective testing strategy. Given a system with n parameters, t-way combinatorial testing, where t is typically much smaller than n, requires that all t-way combinations, i.e., all combinations involving any t parameter values, be covered by at least one test. This dissertation focuses on two important problems in combinatorial testing, including constrained test generation and combinatorial sequence testing. For the first problem, we focus on constraint handling during combinatorial test generation. Constraints over input parameters are restrictions that must be satisfied in order for a test to be valid. Constraints can be handled either using constraint solving or using forbidden tuples. An efficient algorithm is proposed for constrained test generation using constraint solving. The proposed algorithm extends an existing combinatorial test generation algorithm that does not handle constraints, and includes several optimizations to improve the performance of constraint handling. Experimental results on both synthesized and real-life systems demonstrate the effectiveness of the propose algorithm and optimizations. For the second problem, the domain of t-way testing is expanded from test data generation to test sequence generation. Many programs exhibit sequence-related behaviors. We first formally define the system model and coverage for t-way combinatorial sequence testing, and then propose four algorithms for test sequence generation. These algorithms have their own advantages and disadvantages, and can be used for different purposes and in different situations. We have developed a prototype tool that applies t-way sequence testing on Antidote, which is a healthcare data exchange protocol stack. Experimental results suggest that t-way sequence testing can be an effective approach for testing communication protocol implementations.

Software development continues to be an ever-evolving field as organizations require new and innovative programs that can be implemented to make processes more efficient, productive, and cost-effective. Agile practices particularly have shown great benefits for improving the effectiveness of software development and its maintenance due to their ability to adapt to change. It is integral to remain up to date with the most emerging tactics and techniques involved in the development of new and innovative software. The Research Anthology on Agile Software, Software Development, and Testing is a comprehensive resource on the emerging trends of software development and testing. This text discusses the newest developments in agile software and its usage spanning multiple industries. Featuring a collection of insights from diverse authors, this research anthology offers international perspectives on agile software. Covering topics such as global software engineering, knowledge management, and product development, this comprehensive resource is valuable to software developers, software engineers, computer engineers, IT directors, students, managers, faculty, researchers, and academicians.
In his latest work, author Paul C Jorgensen takes his well-honed craftsman’s approach to mastering model-based testing (MBT). To be expert at MBT, a software tester has to understand it as a craft rather than an art. This means a tester should have deep knowledge of the underlying subject and be well practiced in carrying out modeling and testing techniques. Judgment is needed, as well as an understanding of MBT the tools. The first part of the book helps testers in developing that judgment. It starts with an overview of MBT and follows with an in-depth treatment of nine different testing models with a chapter dedicated to each model. These chapters are tied together by a pair of examples: a simple insurance premium calculation and an event-driven system that describes a garage door controller. The book shows how simpler models—flowcharts, decision tables, and UML Activity charts—express the important aspects of the insurance premium problem. It also shows how transition-based models—finite state machines, Petri nets, and statecharts—are necessary for the garage door controller but are overkill for the insurance premium problem. Each chapter describes the extent to which a model can support MBT. The second part of the book gives testers a greater understanding of MBT tools. It examines six commercial MBT products, presents the salient features of each product, and demonstrates using the product on the insurance premium and the garage door controller problems. These chapters each conclude with advice on implementing MBT in an organization. The last chapter describes six Open Source tools to round out a tester’s knowledge of MBT. In addition, the book supports the International Software Testing Qualifications Board’s (ISTQB®) MBT syllabus for certification.
This handbook provides a unique and in-depth survey of the current state-of-the-art in software engineering, covering its major topics, the conceptual genealogy of each subfield, and discussing future research directions. Subjects include foundational areas of software engineering (e.g. software processes, requirements engineering, software architecture, software testing, formal methods, software maintenance) as well as emerging areas (e.g., self-adaptive systems, software engineering in the cloud, coordination technology). Each chapter includes an introduction to central concepts and principles, a guided tour of seminal papers and key contributions, and promising future research directions. The authors of the individual chapters are all acknowledged experts in their field and include many who have pioneered the techniques and technologies discussed. Readers will find an authoritative and concise review of each subject, and will also learn how software engineering technologies have evolved and are likely to develop in the years to come. This book will be especially useful for researchers who are new to software engineering, and for practitioners seeking to enhance their skills and knowledge.
