This book is aimed at everyone preparing for the ISTQB® Certified Tester ¿ Foundation Level exam based on the Foundation Level syllabus (version 4.0) published in 2023. It provides candidates with reliable knowledge based on this document and thus distinguishes itself from all the information about ISTQB® syllabi and exams on the Internet, which is often of rather poor quality and may even contain serious errors. The book expands and details many issues that are described in the new 2023 version of the syllabus in a perfunctory or general way only. According to the ISTQB® guidelines for syllabus-based training, an exercise must be provided for each learning objective at the K3 level, and a practical example must be provided for each objective at the K2 or K3 level. In order to satisfy these requirements, the authors prepared numerous exercises and examples for all learning objectives at these levels. In addition, for each learning objective, one or more sample exam questions are presented which are similar to those that the candidate will see in the exam. This makes the book an excellent aid for studying and preparing for the exam and verifying acquired knowledge.

"Messy code is a nuisance. 'Tidying' code, to make it more readable, requires breaking it up into manageable sections. In this practical guide, author Kent Beck, creator of Extreme Programming and pioneer of software patterns, suggests when and where you might apply tidyings to improve your code while keeping the overall structure of the system in mind. Instead of trying to master tidying all at once, this book lets you try out a few examples that make sense for your problem. If you have a big function containing many lines of code, you'll learn how to logically divide it into smaller chunks. Along the way, you'll learn the theory behind software design: coupling, cohesion, discounted cash flows, and optionality."--Provided by publisher.

Jack the Ripper and legacy codebases have more in common than you'd think. Inspired by forensic psychology methods, you can apply strategies to identify problems in your existing code, assess refactoring direction, and understand how your team influences the software architecture. With its unique blend of criminal psychology and code analysis, Your Code as a Crime Scene arms you with the techniques you need to take on any codebase, no matter what programming language you use. Software development might well be the most challenging task humanity ever attempted. As systems scale up, they also become increasingly complex, expensive to maintain, and difficult to reason about. We can always write more tests, try to refactor, and even fire up a debugger to understand complex coding constructs. That's a great starting point, but you can do so much better. Take inspiration from forensic psychology techniques to understand and improve existing code. Visualize codebases via a geographic profile from commit data to find development hotspots, prioritize technical debt, and uncover hidden dependencies. Get data and develop strategies to make the business case for larger refactorings. Detect and fix organizational problems from the vantage point of the software architecture to remove bottlenecks for the teams. The original Your Code as a Crime Scene from 2014 pioneered techniques for understanding the intersection of people and code. This new edition reflects a decade of additional experience from hundreds of projects. Updated techniques, novel case studies, and extensive new material adds to the strengths of this cult classic. Change how you view software development and join the hunt for better code! What You Need: You need to be comfortable reading code. You also need to use Git (or Subversion, Mercurial or similar version-control tool).

Andreas Heinz führt im Fahrzeugumfeld erstmalig ein Verfahren ein, um ein Messvorhaben mittels ereignisorientierter Datenübertragung zu konzipieren und dessen Durchführbarkeit abzuschätzen. Darüber hinaus zeigt er, wie Messungen effizienter gestaltet bzw. qualitativ hinsichtlich Auflösung und Zeitverhalten optimiert werden können. Dabei werden gegebene Sicherheitsanforderungen und normative Vorgaben stets eingehalten und eine Buslastberechnung für den CAN eingeführt, die zusätzliche Buslasten für Messzwecke berücksichtigen kann. Dies ermöglicht dem Autor, im Vorfeld der Messung eine Aussage treffen zu können, ob diese Messaufgabe für einen sicheren Einsatz im realen Fahrbetrieb realisierbar ist oder nicht.

This book evaluates the contributions of the electronic control unit software of an electric vehicle on sustainability and society, such as the reduction of emissions during a product design and the improvements in the vehicle.A sustainable transport model is proposed, demonstrating its economic viability. By validating software in a more efficient way and adding new functionalities to the software to enhance driving efficiency, energy consumption can be significantly reduced. Therefore, software validation and development have a significant impact on sustainability. This book offers innovative validation solutions based on artificial intelligence techniques to reduce validation time and emissions.The impact of driving efficiency on sustainable transport models is studied in detail, making proposals to be considered in the current environmental policies under discussion within the European Union in order to improve the sustainability of transport models.Vehicles are becoming sophisticated electronic systems due to the fact that they are integrating a significant number of electronic control units. This trend will certainly continue in the year to come. Consequently, software validation techniques are a key element for car manufacturers in order to ensure the quality of the vehicle. This book contributes to these efforts.
