Part of any software development is to regularly inform management about the progress and any problems of the project. This book presents various test parameters and metrics that can be used to vividly illustrate the progress of a software test and easily identify any need for action. The key parameters and index values that are essential for successful reporting are explained in detail.Starting with the historical development of test reporting, the author explains the fundamental benefits of metrics and provides an overview of the different types of metrics and how they can be used effectively in software testing. He shows how a particular metric can be individually adapted to the software to be tested, starting with the test specification and test execution through to the development of test coverage, and how this can lead to test automation. He also presents the advantages and disadvantages of those test metrics that are based on defects, i.e. that measure the number of defects, the defect density and the development of defects over time.With this detailed examination of test reporting, the author provides an optimal basis for evaluation, which not only allows the assessment of which test metric should be used for which purpose or which individual project situation, but also what the particular problems of an individual metric for test reporting may be and how these problems can best be solved. This practical guide is therefore primarily aimed at employees in IT projects, such as project managers, software testers and developers, but business and technology consultants as well as lecturers at colleges and universities will also find an exciting insight into various software testing methods.

This book explains the most important technical terms and contents and assigns them to the corresponding areas. It also includes seemingly peripheral areas that play a role in information security. For instance, the topic complexes of functional Safety and Privacy are examined in terms of their similarities and differences. The book presents currently used attack patterns and how to protect against them. Protection must be implemented on both a technical level (e.g., through the use of cryptography) and on an organizational and personnel level (e.g., through appropriate management systems and awareness training). How can one determine how secure data is? How can relevant threats be identified that need protection? How do risk analyses proceed?

This book constitutes the refereed proceedings of the 16th Software Quality Days Conference, SWQD 2024, held in Vienna, Austria, during April 23-25, 2024.

Many books have been written about software testing, but most of them discuss the general framework of testing from a traditional perspective. Unfortunately, traditional test design techniques are often ineffective and unreliable for revealing the various kinds of faults that may occur. This book introduces three new software testing techniques: Two-Phase Model-Based Testing, the Action-State Testing, and the General Predicate Testing, all of which work best when applied with efficient fault revealing capabilities. You'll start with a short recap of software testing, focusing on why risk analysis is obligatory, how to classify bugs practically, and how fault-based testing can be used for improving test design. You'll then see how action-state testing merges the benefits of state transition testing and use case testing into a unified approach. Moving on you'll look at general predicate testing and how it serves as an extension of boundary value analysis, encompassing morecomplex predicates. Two-phase model-based testing represents an advanced approach where the model does not necessarily need to be machine-readable; human readability suffices. The first phase involves a high-level model from which abstract tests are generated. Upon manual execution of these tests, the test code is generated. Rather than calculating output values, they are merely checked for conformity. The last part of this book contains a chapter on how developers and testers can help each other and work as a collaborative team. What You'll LearnApply efficient test design techniques for detecting domain faultsWork with modeling techniques that combine all the advantages of state transition testing and uses case testingGrasp the two-phase model-based testing technique Use test design efficiently to find almost all the bugs in an applicationWho This Book Is ForSoftware developers, QA engineers, and, business analysts

Every day, successful software projects scale and sustain businesses of all sizes and across all industries. Unfortunately, the reality is that many software projects still fail. The reasons behind these failures are seldom due to the underlying technology. Misunderstandings and communication barriers lead to wrong decisions, missed opportunities, communication breakdowns, or worse—huge economic loss. In this digitally connected world, business professionals can't afford to be hands-off on technical projects, but they also can't be expected to have technical certifications. They have first-hand knowledge of the business processes, are subject matter experts in software requirements, and they finance the projects. Even C-level management or board members need to rapidly gain just enough understanding of technology to make mission-critical decisions for businesses to survive and flourish. In most software projects the number of non-technical stakeholders far exceeds the numberof techies. This book distills the world of software projects into simple terms and relatable metaphors for even the most technically adverse reader. Real-life examples, entertaining analogies, and hand-drawn illustrations will stick with readers throughout their own software projects, bolstering their success. Business requirements, use cases, process flows—the list goes on. It's all broken down in this game-changing book aimed at delivering for business and tech teams what DevOps has done for developers and operations. What You Will Learn Know the importance of good business requirements and how to write themIdentify the most important business roles, key decisions, and critical activities involved in software projectsStrengthen collaboration between non-technical and technical teamsGrasp common software project terminology, required for non-techies Understand the software development life cycleGain insight on the common software project methodologies and how they differUnderstand what software developers do at a high level Who This Book Is ForNon-technical business professionals (such as small business owners, startup founders, or employees of a business of any size or industry) who need to secure and implement a software solution. The reader may supervise or collaborate with technical teams, and may be a (beginning) software developer looking for practical insights and better ways to communicate with business colleagues.

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.

There is a call to action reverberating in company boardrooms, earnings calls, technology conferences, and IT departments: every company should be a software company. The call makes intuitive sense. Software, when done right, creates infinite business leverage. It is not a coincidence that 7 out of 10 largest companies in the world are software companies. But how does a company become a software company? This book will​ help enterprises transform into a software company.The software-driven future that Marc Andreessen predicted in his now-famous 2011 essay is here but unevenly distributed. While enterprises, and teams within, grasp the software technologies, they lack the context to leverage them — much less understand the fundamental principles that drive the business value from software: What is the real essence of the software-based transformation? If every enterprise is implementing the same technologies, what is the sourceof differentiation? How do you manage the inherent complexity of software such that it doesn't destroy software's value? How do you build and nurture talent so that it is empowered to create the best solutions for your customers'problems? This book will answer all of that and more.The boundary between enterprise and consumer software is rapidly blurring. IEEE reports that 40% of the cost of a new car comes from software. Elsewhere, software is becoming synonymous with medical devices and therapeutics. FinTech and EdTech trends are primarily about personalization through software at an internet-scale. The struggling enterprises are up against it. They have no choice but to figure out how to ship consumer-grade software. It is an existential problem for them.This book compiles the timeless principles of building good software, yet often disregarded while building and deploying software products for enterprises.What You'll LearnLeverage people to build creative software solutionsManage development complexity so that we keep software focused on user problemsUnderstand software technology as a means of producing valueWho This Book Is ForEnterprise Executive Management, Enterprise IT Management Professionals, Software Practitioners within Enterprise

This book discusses theoretically and empirically the trade-off relationship between the frequency of product adaptation activities and the constraints on development resources, and how companies can respond to these constraints. The objective of this book is to identify effective management practices in continuous product development. With the continuation of development activities, companies are required to constantly adapt their products to changes in the external environment. In continuous product development, the development process extends beyond product release, and interaction with the external environment is not limited to the planning stage but occurs multiple times throughout the process. What impact does the multiple adaptation activities have on the product performance as development activities become more continuous, and how to use limited development resources to provide stable and constant high-quality adaptation activities with optimal frequency have become urgent issues in the development sites. To address these research questions, this book focuses primarily on the development activities of the online game industry.

This book aims to facilitate and improve development work related to all documents and information required by functional safety standards. Proof of Compliance (PoC) is important for the assessor and certification bodies when called up to confirm that the manufacturer has developed a software system according to the required safety standards. While PoC documents add functionality to the product neither for the developer nor for the customer, they do add confidence and trust to the product and ease certification, and as such are important for the product's value. In spite of this added value, the documentation needed for PoC is often developed late in the project and in a haphazard manner. This book aims at developers, assessors, certification bodies, and purchasers of safety instrumented systems and informs the reader about the most important PoC documents. A typical PoC documentation encompasses 50 to 200 documents, several of which are named in the safety standards (e.g., 82 documents in IEC 61508:2010 series, 101 documents in EN 5012X series and 106 work products in ISO 26262:2018 series). These documents also include further references, typically one to twenty of them, and the total number of pages developed by the manufacturer varies between 2000 and 10000 pages. The book provides guidance and examples what to include in the relevant plans and documents.

Use this book to learn the Distributed Application Runtime (Dapr), a new event-driven runtime from Microsoft designed to help developers build microservices applications, using a palette of languages and frameworks that run everywhere: on-premises, in any cloud, and even on the edge.One of the most popular architectural patterns for implementing large, complex, distributed solutions is the microservices architectural style. Because solutions are composed of services based on various languages, frameworks, and platforms, the more complex and compartmentalized an application becomes, the more considerations a developer has to keep in mind. Much of the time this proves to be difficult.Introducing Distributed Application Runtime (Dapr) is your guide to achieving more with less through patterns. Part I of the book is about understanding microservices and getting up and running with Dapr, either on your machine or in any Kubernetes cluster. From there you are guided through the concepts of Dapr, how it works, and what it can do for you. You will wrap up with various ways to debug Dapr applications using Visual Studio Code locally, inside a container or Kubernetes. In Part II you will jump into the reusable patterns and practices, the building blocks of Dapr. You will go from service invocation, publish and subscribe, state management, resource bindings, and the Actor model to secrets; each building block is covered in detail in its own dedicated chapter. You will learn what Dapr offers from a functional perspective and also how you can leverage the three pillars of observability (logs, metrics, and traces) in order to gain insight into your applications. In Part III you will explore advanced concepts, including using middleware pipelines, integrating Dapr into web frameworks such as ASP.NET Core, or the runtimes of Azure Logic Apps and Azure Functions. The book features a multi-versed set of examples that cover not only the plain API of Dapr, but also the.NET SDK. Hence, most of the examples are in.NET 5, with a small number in JavaScript to exemplify the use of multiple languages. Examples show you how to securely use Dapr to leverage a variety of services in Microsoft Azure, including Azure Kubernetes Service, Azure Storage, Azure Service Bus, Azure Event Grid, Azure Key Vault, Azure Monitor, and Azure Active Directory among others. What You Will LearnRecognize the challenges and boundaries of microservices architectureHost Dapr inside a Kubernetes cluster or as a standalone processLeverage and use Dapr's ready-to-use patterns and practicesUtilize its HTTP/gRPC APIsUse Dapr with ASP.NET Core and in.NET applications (with or without the SDK)Implement observability for Dapr applicationsSecure Dapr applicationsIntegrate Dapr with the runtime of Azure Logic Apps and Azure FunctionsRealize the full potential of Visual Studio Code by using the right extensions that will contribute to a better development experienceWho This Book Is ForDevelopers and architects who want to utilize a proven set of patterns to help easily implement microservices applications

Program debugging has always been a difficult and time-consuming task in the context of software development, where spectrum-based fault localization (SBFL) is one of the most widely studied families of techniques. While it's not particularly difficult to learn about the process and empirical performance of a particular SBFL technique from the available literature, researchers and practitioners aren't always familiar with the underlying theories. This book provides the first comprehensive guide to fundamental theories in SBFL, while also addressing some emerging challenges in this area. The theoretical framework introduced here reveals the intrinsic relations between various risk evaluation formulas, making it possible to construct a formula performance hierarchy. Further extensions of the framework provide a sufficient and necessary condition for a general maximal formula, as well as performance comparisons for hybrid SBFL methods. With regard to emerging challenges in SBFL, the book mainly covers the frequently encountered oracle problem in SBFL and introduces a metamorphic slice-based solution. In addition, it discusses the challenge of multiple-fault localization and presents cutting-edge approaches to overcoming it. SBFL is a widely studied research area with a massive amount of publications. Thus, it is essential that the software engineering community, especially those involved in program debugging, software maintenance and software quality assurance (including both newcomers and researchers who want to gain deeper insights) understand the most fundamental theories – which could also be very helpful to ensuring the healthy development of the field.

Write automated unit tests for the ABAP language. This book teaches programmers using simple examples and metaphors and explains the underlying concepts of writing effective automated unit tests. Many, if not most, ABAP programmers learned their programming and testing skills before the ABAP development environment provided an automated unit testing facility. Automated Unit Testing with ABAP: A Practical Approach offers hope and salvation to ABAP programmers who continue to toil with antiquated manual unit testing processes, taking them by the hand and lifting them out of that dungeon of despair with a modern and proven alternative. It begins by explaining how the xUnit family of automated testing frameworks provides a quick and effective means of insuring high-quality software. It then focuses on the ABAP Unit Testing Facility, the xUnit framework applicable specifically to the ABAP language, showing how it can be used to bring ABAP applications underautomated testing control, from old legacy applications to those newly written.Whereas xUnit testing has been widely accepted with developers writing in many other programming languages, it is an unfortunate fact in the ABAP community that many programmers still are unfamiliar with xUnit concepts and do not know how to begin implementing automated unit testing into their development process. This book demonstrates how to refactor programs so they become designed for testability, showing how to use process encapsulation and test isolation to facilitate automated testing, including a thorough explanation of test-driven development and the use of test doubles. The book: Shows how to write automated unit tests for ABAPInstills ABAP programmers with the confidence to refactor poorly written codeExplains how an automated testing harness facilitates rapid software developmentTeaches how to utilize test-driven development (TDD) withABAPOffers advice and tips on the best ways to write automated unit tests What You Will Learn Become familiar with the xUnit approach to testingKnow the ABAP statements that interfere with running automated unit tests and how to accommodate themUnderstand what it means to isolate code for testing and how this is achievedGain the confidence to refactor poorly written codeMake ABAP programs designed for testabilityReap the benefits of spending less time manually unit testing ABAP programsUse test-driven development (TDD) with ABAP programmingUse configurable test doubles in ABAP Who This Book Is ForABAP programmers who remain unfamiliar with the automated unit testing facility and those who already use it butwant to improve their skill writing and using automated tests. The book addresses the reluctance and trepidation felt by procedural ABAP programmers who need to know some object-oriented concepts to use this facility, expands their horizons, and helps them step through the doorway leading to a different approach to program design.
