As a society today, we are so dependent on systems-of-systems that any malfunction has devastating consequences, both human and financial. Their technical design, functional complexity and numerous interfaces justify a significant investment in testing in order to limit anomalies and malfunctions. Based on more than 40 years of practice in the development and testing of systems, including safety-critical systems, this book discusses development models, testing methodologies and techniques, and identifies their advantages and disadvantages. Pragmatic and clear, this book displays many examples and references that will help you improve the quality of your systemsof-systems efficiently and effectively and lead you to identify the impact of upstream decisions and their consequences. Advanced Testing of Systems-of-Systems 1 is complemented by a second volume dealing with the practical implementation and use of the techniques and methodologies proposed here.
Les tests logiciels nécessitent des connaissances de base qui sont couvertes par la certification ISTQB niveau fondation. Celle-ci devient un prérequis pour commencer une carrière dans le monde du test de logiciels. Couvrant chaque section du syllabus ISTQB fondation (v. 2018), Les tests de logiciels 1 présente les différents concepts, analyse les processus et étudie les techniques de base nécessaires pour détecter les défauts dans les logiciels, indépendamment de la méthode de développement (agile ou séquentielle). Cet ouvrage apporte des réponses pragmatiques pour les professionnels sur la gestion des tests selon les risques, le calcul de rentabilité et le retour sur investissement des tests logiciels. Il fournit un référentiel à destination des DSI, MOE et MOA et traite des aspects de remontée d’informations, d’estimation de charge et de suivi. Outre ces explications détaillées, il prépare à la certification en fournissant la terminologie, ainsi que des QCM et un examen blanc, pour réussir avec succès l’examen de certification de l’ISTQB.
The testing market is growing at a fast pace and ISTQB certifications are being increasingly requested, with more than 180,000 persons currently certified throughout the world. The ISTQB Foundations level syllabus was updated in 2011, and this book provides detailed course study material including a glossary and sample questions to help adequately prepare for the certification exam. The fundamental aspects of testing are approached, as is testing in the lifecycles from Waterfall to Agile and iterative lifecycles. Static testing, such as reviews and static analysis, and their benefits are examined as well as techniques such as Equivalence Partitioning, Boundary Value Analysis, Decision Table Testing, State Transitions and use cases, along with selected white box testing techniques. Test management, test progress monitoring, risk analysis and incident management are covered, as are the methods for successfully introducing tools in an organization. Contents 1. Fundamentals of Testing. 2. Testing Throughout the Software Life Cycle. 3. Static Techniques (FL 3.0). 4. Test Design Techniques (FL 4.0). 5. Test Management (FL 5.0). 6. Tools support for Testing (FL 6.0). 7. Mock Exam. 8. Templates and Models. 9. Answers to the Questions.
Softwaretests stellen eine kritische Phase in der Softwareentwicklung dar. Jetzt zeigt sich, ob das Programm die entsprechenden Anforderungen erfüllt und sich auch keine Programmierungsfehler eingeschlichen haben. Doch wie bei allen Phasen im Software-Entwicklungsprozess gibt es auch hier eine Reihe möglicher Fallstricke, die die Entdeckung von Programmfehlern vereiteln können. Deshalb brauchen Softwaretester ein Handbuch, das alle Tipps, Tricks und die häufigsten Fehlerquellen genau auflistet und erläutert, damit mögliche Testfehler von vornherein vermieden werden können. Ein solches Handbuch ersetzt gut und gerne jahr(zehnt)elange Erfahrung und erspart dem Tester frustrierende und langwierige Trial-und-Error-Prozeduren. Chem Kaner und James Bach sind zwei der international führenden Experten auf dem Gebiet des Software Testing. Sie schöpfen hier aus ihrer insgesamt 30-jährigen Erfahrung. Die einzelnen Lektionen sind nach Themenbereichen gegliedert, wie z.B. Testdesign, Test Management, Teststrategien und Fehleranalyse. Jede Lektion enthält eine Behauptung und eine Erklärung sowie ein Beispiel des entsprechenden Testproblems. "Lessons Learned in Software Testing" ist ein unverzichtbarer Begleiter für jeden Software Tester.

As a society today, we are so dependent on systems-of-systems that any malfunction has devastating consequences, both human and financial. Their technical design, functional complexity and numerous interfaces justify a significant investment in testing in order to limit anomalies and malfunctions. Based on more than 40 years of practice, this book goes beyond the simple testing of an application – already extensively covered by other authors – to focus on methodologies, techniques, continuous improvement processes, load estimates, metrics and reporting, which are illustrated by a case study. It also discusses several challenges for the near future. Pragmatic and clear, this book displays many examples and references that will help you improve the quality of your systemsof-systems efficiently and effectively and lead you to identify the impact of upstream decisions and their consequences. Advanced Testing of Systems-of-Systems 2 deals with the practical implementation and use of the techniques and methodologies proposed in the first volume.
The purpose of the Software Test Handbook effort was to provide Air Force software developers with guidelines and methodology for the effective use of higher order language (HOL) software testing techniques and in the selection of automated tools for the testing of computer programs. The effort resulted in a two volume final technical report. This report, Volume I - Final Technical Report, describes the total contractual effort including a project overview, summary for each of three technical tasks, and a bibliography. Volume II, the Software Test Guidebook, contains the guidelines and methodology resulting from the effort.
This book constitutes the refereed proceedings of the 6th International Conference on Test and Proofs, TAP 2012, held in Prague, Czech Republic, in May/June 2012, as part of the TOOLS 2012 Federated Conferences. The 9 revised full papers presented together with 2 invited papers, 4 short papers and one tutorial were carefully reviewed and selected from 29 submissions. The papers are devoted to the convergence of tests and proofs for developing novel techniques and application that support engineers in building secure, safe, and reliable systems. Among the topics covered are model-based testing; scenario-based testing; complex data structure generation; and the validation of protocols and libraries.
