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.

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.

In an article for Wired Magazine in 2006, Jeff Howe defined crowdsourcing as an idea for outsourcing a task that is traditionally performed by a single employee to a large group of people in the form of an open call. Since then, by modifying crowdsourcing into different forms, some of the most successful new companies on the market have used this idea to make people's lives easier and better. On the other hand, software testing has long been recognized as a time-consuming and expensive activity. Mobile application testing is especially difficult, largely due to compatibility issues: a mobile application must work on devices with different operating systems (e.g. iOS, Android), manufacturers (e.g. Huawei, Samsung) and keypad types (e.g. virtual keypad, hard keypad). One cannot be 100% sure that, just because a tested application works well on one device, it will run smoothly on all others.Crowdsourced testing is an emerging paradigm that can improve the cost-effectiveness of software testing and accelerate the process, especially for mobile applications. It entrusts testing tasks to online crowdworkers whose diverse testing devices/contexts, experience, and skill sets can significantly contribute to more reliable, cost-effective and efficient testing results. It has already been adopted by many software organizations, including Google, Facebook, Amazon and Microsoft. This book provides an intelligent overview of crowdsourced testing research and practice. It employs machine learning, data mining, and deep learning techniques to process the data generated during the crowdsourced testing process, to facilitate the management of crowdsourced testing, and to improve the quality of crowdsourced testing.

The "Black Magic Probe" is a debug probe for ARM Cortex microcontrollers, supporting SWD and JTAG. What sets it apart from other debug probes is that it directly supports the Remote Server Protocol of GDB (also used by LLDB and other debugging and development tools). This quashes the need for additional middleware, services or drivers, and thereby makes the software/hardware toolchain simpler, more portable and more reliable.What you can do with the Black Magic Probe is:¿ Download code into Flash ROM or RAM of the microcontroller.¿ Step through code, look at a backtrace of the call stack.¿ Set up to six breakpoints in Flash ROM (as well as unlimited breakpoints in RAM).¿ Set up to four data watchpoints, to check for data reads or writes.¿ Inspect and modify variables, memory and registers.¿ Run the code and follow it with real-time tracing.¿ Profile your code, to gain insight in where it spends its cycles.This book focuses on the original Black Magic Probe, but it also covers a few "open hardware" variants - such as the ctxLink probe, which offers truly remote debugging, due to its Wi-Fi interface and rechargeable battery.

More than ever, we depend on software to get through our everyday lives. It's embedded in our smartphones, cars, children's toys, and household appliances (even our toasters), and it's transforming our world. This brave new world of technology offers exciting opportunities, but it has never been more important that we recognize and understand the risks to our security and safety. When software goes bad, the consequences can range from the farcical (such as the HealthCare.gov fiasco, in which a highly-touted government website crashed almost immediately upon being launched) to the tragic (as in the case of the Arizona woman who was killed by a self-driving car that didn't recognize her as a pedestrian).Testing is our line of defence against these software-related catastrophes. Yet, for years, it was seen as an afterthought-a chore that developers only carried out because they had to, and which they tried to complete as cheaply and quickly as possible.In The Book on Testing, Alex Rodov leads the reader on a personal and informal tour of the software-testing landscape, focusing on what happens when it isn't done properly. In easy-to-understand language, he offers real-life examples, as well as insights gained from decades of experience, to demonstrate why it doesn't have to be that way. Testing is difficult and can never be perfect. But if it's done well, we'll all be able to sleep better at night.

Learn to write better automated tests that will dramatically increase your productivity and have fun while doing so. This book is a build-your-own adventure designed for individual reading and for collaborative workshops. You will build an xUnit automated test framework using JavaScript: initially a clone of Jest, but adding a couple of neat features borrowed from RSpec, the genre-defining tool for behavior-driven development (BDD). Along the way, you will explore the philosophy behind automated testing best practices. The automated test runner is one of the most important innovations within software engineering. But for many programmers, automated testing remains a mystery, and knowing how to write good tests is akin to sorcery.As the chapters of this book unfold, you will see how the humble test runner is an elegant and simple piece of software. Each chapter picks a single feature to build, like the "it" function or the "beforeEach" block. It picks apart the theory of why the feature needs to exist, and how to use it effectively in your own test suites. Every chapter ends with a set of ideas for extension points should you wish to explore further, alone or in groups. The book culminates in an implementation of test doubles and mocks¿one of the most difficult and misunderstood concepts within automated testing.By the end of the book, you will have gained a solid understanding of automated testing principles that you can immediately apply to your work projects.
