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. You will: Build an xUnit automated test framework See how an automated test runner works Understand the best practices for automated unit testing Effectively use test doubles and mocks.

This textbook shows how to develop the functional requirements of (information) systems. It emphasizes the importance to consider the complete development path of a functional requirement, i.e. not only the individual development steps but also their proper combination and their alignment. The book consists of two parts: Part I presents the underlying theory while Part II contains various illustrative case studies. Part I starts with an introduction to the topic (Chapter 1). Then it explains how to develop functional requirements that represent the conceptual dynamics of an information system (Chapters 2 and 3). Chapters 4 and 5 explain how to model the conceptual statics of an information system. Chapter 6 gives some directions for implementation. Finally, Chapter 7 explains how a ‘technical manager’ can organize and manage the development process. As an illustration of the theory, Part II contains three substantial case studies. The first one (Chapter 8) presents a stepwise development starting from an informal situation sketch via a simple domain model towards a precisely specified, full-fledged conceptual data model, which finally is translated to an SQL database. In the second case study (Chapter 9) the author converts the well-known non-trivial use case Process Sale from Larman into a textual System Sequence Description (SSD). For validation purposes, that textual SSD is subsequently translated into natural language and into a graphical SSD. The third case study (Chapter 10) shows the applicability of the author’s approach to a control system and also illustrates the typical situation that the requirements are constantly changing during development. This book is written for (under)graduate students in software engineering or information systems who want to learn how to carry out adequate problem analysis, to make good system specifications, and/or to understand how to organize and manage an IS-development process. It also targets practitioners who want to improve their problem analysis abilities and/or their ability to make good system specifications. To this end, it includes more than 150 explanatory figures and is accompanied by a Web site which provides additional course material such as slides, additional exercises, solutions to exercises, and the code for the figures used in the book. .

This book constitutes the refereed proceedings of the 29th International Working Conference on Requirements Engineering: Foundation for Software Quality, REFSQ 2023, which took place in Barcelona, Spain, during April 17-20, 2023. The 12 full technical design and scientific evaluation papers, 8 short research previews and vision papers, and 5 experience reports presented in this volume were carefully reviewed and selected from 78 submissions. They were organized in topical sections as follows: Requirements communication and conceptualization; NLP and machine learning for AI; RE for artificial intelligence; crowd RE; and RE in practice.

This book analyses several aspects of Hybrid Annuity Model (HAM), a form of hybrid public-private partnership (PPP) for development of roads sector in India. The book covers contractual, financing, taxation and accounting aspects of the HAM based PPP projects in India and provides a complete multi-dimensional view for readers. It is a comprehensive guide for multiple stakeholders involved in the development of infrastructure projects in developing economies across globe. The book is authored by professionals having hands-on advisory experience for HAM PPP projects in India. Given that these are long-term concession agreements (around 15 years), there are inherent complications and the authors have tried to provide clarity on practical issues. The book adopts a novel case-study approach. Based on detailed financial and commercial assumptions for a road project in India, the authors have used around 100 numerical illustrations to provide a quantitative and qualitative understanding for readers. Another highlight of the book is use of international case-studies to provide key learnings in areas of project preparation and structuring for such hybrid PPP models. The risk allocation framework is also contrasted with the HAM PPP model to highlight the key differences. The international case studies have been selected from transport and water sector to illustrate the applicability of hybrid PPPs across multiple sectors to support sustainable infrastructure development. The target audience for this book include private sector developers, government agencies, deal practitioners, advisors, researchers and academia . This book will also serve as a useful guide for commercial lenders, development finance institutions (DFIs) and institutional investors who are looking to finance such infrastructure projects in the long term.
