Model checking is a powerful approach for the formal verification of software. When applicable, it automatically provides complete proofs of correctness, or explains, via counter-examples, why a system is not correct. This book provides a basic introduction to this new technique. The first part describes in simple terms the theoretical basis of model checking: transition systems as a formal model of systems, temporal logic as a formal language for behavioral properties, and model-checking algorithms. The second part explains how to write rich and structured temporal logic specifications in practice, while the third part surveys some of the major model checkers available.

An essential introduction to the analysis and verification of control system software The verification of control system software is critical to a host of technologies and industries, from aeronautics and medical technology to the cars we drive. The failure of controller software can cost people their lives. In this authoritative and accessible book, Pierre-Loïc Garoche provides control engineers and computer scientists with an indispensable introduction to the formal techniques for analyzing and verifying this important class of software. Too often, control engineers are unaware of the issues surrounding the verification of software, while computer scientists tend to be unfamiliar with the specificities of controller software. Garoche provides a unified approach that is geared to graduate students in both fields, covering formal verification methods as well as the design and verification of controllers. He presents a wealth of new verification techniques for performing exhaustive analysis of controller software. These include new means to compute nonlinear invariants, the use of convex optimization tools, and methods for dealing with numerical imprecisions such as floating point computations occurring in the analyzed software. As the autonomy of critical systems continues to increase—as evidenced by autonomous cars, drones, and satellites and landers—the numerical functions in these systems are growing ever more advanced. The techniques presented here are essential to support the formal analysis of the controller software being used in these new and emerging technologies.

The World is lacking an in-depth technical book describing the meth ods and techniques used to provide confidence in our system software. Not only is the U.S. government more focused on software safety in to day's market, but private industry and academia are as well. The methods and techniques that provide such confidence are commonly called software verification and validation. Software Verification and Validation: An Engineering and Scientific Approach, a professional book, fills the critical need for an in-depth tech nical reference providing the methods and techniques for building and maintaining confidence in many varieties of system software. The intent of this volume is to help develop reliable answers to such critical questions as: 1) Are we building the right software for the need? 2) Are we building the software right? Software Verification and Validation: An Engineering and Scientific Approach is structured for research scientists and practitioners in industry.

Modern embedded systems require high performance, low cost and low power consumption. Such systems typically consist of a heterogeneous collection of processors, specialized memory subsystems, and partially programmable or fixed-function components. This heterogeneity, coupled with issues such as hardware/software partitioning, mapping, scheduling, etc., leads to a large number of design possibilities, making performance debugging and validation of such systems a difficult problem. Embedded systems are used to control safety critical applications such as flight control, automotive electronics and healthcare monitoring. Clearly, developing reliable software/systems for such applications is of utmost importance. This book describes a host of debugging and verification methods which can help to achieve this goal. - Covers the major abstraction levels of embedded systems design, starting from software analysis and micro-architectural modeling, to modeling of resource sharing and communication at the system level - Integrates formal techniques of validation for hardware/software with debugging and validation of embedded system design flows - Includes practical case studies to answer the questions: does a design meet its requirements, if not, then which parts of the system are responsible for the violation, and once they are identified, then how should the design be suitably modified?

“The situation is good, but not hopeless” (Polish folk wisdom) The text is devoted to the Software Analysis and Testing (SAT) methods and s- porting tools for assessing and, if possible, improving software quality, specifically its correctness. The term quality assurance is avoided for it is this author’s firm belief that in the current state of the art that goal is unattainable, a plethora of “gu- anteed” solutions to the problem notwithstanding. Therefore, the rather awkward phrase “improving correctness” is to be understood as an effort to minimize the number of residual programming faults (“bugs”) and their impact on the software’s behavior, that is, to make the faults tolerable. It is clear that such a minimalist approach is a result of frustration. Indeed, having spent years developing software and teaching (preaching?) “How to do it right,” I still do not know how to go about it with any degree of certainty! It appears then I probably should stop right now, for who with a modicum of common sense would reach for a text that does not offer salvation but (as will be seen) hard work and misery? If I intend to continue, it is only that I suspect there are many professionals out there who have similar doubts. And they are the intended audience of this project. The philosophical underpinning of the text is the importance of sound engine- ing practices in software development.

This book discusses automated string-analysis techniques, focusing particularly on automata-based static string analysis. It covers the following topics: automata-bases string analysis, computing pre and post-conditions of basic string operations using automata, symbolic representation of automata, forward and backward string analysis using symbolic automata representation, constraint-based string analysis, string constraint solvers, relational string analysis, vulnerability detection using string analysis, string abstractions, differential string analysis, and automated sanitization synthesis using string analysis. String manipulation is a crucial part of modern software systems; for example, it is used extensively in input validation and sanitization and in dynamic code and query generation. The goal of string-analysis techniques and this book is to determine the set of values that string expressions can take during program execution. String analysis can be used to solve many problems in modern software systems that relate to string manipulation, such as: (1) Identifying security vulnerabilities by checking if a security sensitive function can receive an input string that contains an exploit; (2) Identifying possible behaviors of a program by identifying possible values for dynamically generated code; (3) Identifying html generation errors by computing the html code generated by web applications; (4) Identifying the set of queries that are sent to back-end database by analyzing the code that generates the SQL queries; (5) Patching input validation and sanitization functions by automatically synthesizing repairs illustrated in this book. Like many other program-analysis problems, it is not possible to solve the string analysis problem precisely (i.e., it is not possible to precisely determine the set of string values that can reach a program point). However, one can compute over- or under-approximations of possible string values. If the approximations are precise enough, they can enable developers to demonstrate existence or absence of bugs in string manipulating code. String analysis has been an active research area in the last decade, resulting in a wide variety of string-analysis techniques. This book will primarily target researchers and professionals working in computer security, software verification, formal methods, software engineering and program analysis. Advanced level students or instructors teaching or studying courses in computer security, software verification or program analysis will find this book useful as a secondary text.

At the dawn of the 21st century and the information age, communication and c- puting power are becoming ever increasingly available, virtually pervading almost every aspect of modern socio-economical interactions. Consequently, the potential for realizing a signi?cantly greater number of technology-mediated activities has emerged. Indeed, many of our modern activity ?elds are heavily dependant upon various underlying systems and software-intensive platforms. Such technologies are commonly used in everyday activities such as commuting, traf?c control and m- agement, mobile computing, navigation, mobile communication. Thus, the correct function of the forenamed computing systems becomes a major concern. This is all the more important since, in spite of the numerous updates, patches and ?rmware revisions being constantly issued, newly discovered logical bugs in a wide range of modern software platforms (e. g. , operating systems) and software-intensive systems (e. g. , embedded systems) are just as frequently being reported. In addition, many of today’s products and services are presently being deployed in a highly competitive environment wherein a product or service is succeeding in most of the cases thanks to its quality to price ratio for a given set of features. Accordingly, a number of critical aspects have to be considered, such as the ab- ity to pack as many features as needed in a given product or service while c- currently maintaining high quality, reasonable price, and short time -to- market.

“Don’s book is a very good addition both to the testing literature and to the literature on quality assurance and software engineering... . [It] is likely to become a standard for test training as well as a good reference for professional testers and developers. I would also recommend this book as background material for negotiating outsourced software contracts. I often work as an expert witness in litigation for software with very poor quality, and this book might well reduce or eliminate these lawsuits....” –Capers Jones, VP and CTO, Namcook Analytics LLC Software and system testers repeatedly fall victim to the same pitfalls. Think of them as “anti-patterns”: mistakes that make testing far less effective and efficient than it ought to be. In Common System and Software Testing Pitfalls, Donald G. Firesmith catalogs 92 of these pitfalls. Drawing on his 35 years of software and system engineering experience, Firesmith shows testers and technical managers and other stakeholders how to avoid falling into these pitfalls, recognize when they have already fallen in, and escape while minimizing their negative consequences. Firesmith writes for testing professionals and other stakeholders involved in large or medium-sized projects. His anti-patterns and solutions address both “pure software” applications and “software-reliant systems,” encompassing heterogeneous subsystems, hardware, software, data, facilities, material, and personnel. For each pitfall, he identifies its applicability, characteristic symptoms, potential negative consequences and causes, and offers specific actionable recommendations for avoiding it or limiting its consequences. This guide will help you Pinpoint testing processes that need improvement–before, during, and after the project Improve shared understanding and collaboration among all project participants Develop, review, and optimize future project testing programs Make your test documentation far more useful Identify testing risks and appropriate risk-mitigation strategies Categorize testing problems for metrics collection, analysis, and reporting Train new testers, QA specialists, and other project stakeholders With 92 common testing pitfalls organized into 14 categories, this taxonomy of testing pitfalls should be relatively complete. However, in spite of its comprehensiveness, it is also quite likely that additional pitfalls and even missing categories of pitfalls will be identified over time as testers read this book and compare it to their personal experiences. As an enhancement to the print edition, the author has provided the following location on the web where readers can find major additions and modifications to this taxonomy of pitfalls: http://donald.firesmith.net/home/common-testing-pitfalls Please send any recommended changes and additions to dgf (at) sei (dot) cmu (dot) edu, and the author will consider them for publication both on the website and in future editions of this book.
