Description : If you program in C++ you've been neglected. Test-driven development (TDD) is a modern software development practice that can dramatically reduce the number of defects in systems, produce more maintainable code, and give you the confidence to change your software to meet changing needs. But C++ programmers have been ignored by those promoting TDD--until now. In this book, Jeff Langr gives you hands-on lessons in the challenges and rewards of doing TDD in C++. Modern C++ Programming With Test-Driven Development, the only comprehensive treatment on TDD in C++ provides you with everything you need to know about TDD, and the challenges and benefits of implementing it in your C++ systems. Its many detailed code examples take you step-by-step from TDD basics to advanced concepts. As a veteran C++ programmer, you're already writing high-quality code, and you work hard to maintain code quality. It doesn't have to be that hard. In this book, you'll learn: how to use TDD to improve legacy C++ systems how to identify and deal with troublesome system dependencies how to do dependency injection, which is particularly tricky in C++ how to use testing tools for C++ that aid TDD new C++11 features that facilitate TDD As you grow in TDD mastery, you'll discover how to keep a massive C++ system from becoming a design mess over time, as well as particular C++ trouble spots to avoid. You'll find out how to prevent your tests from being a maintenance burden and how to think in TDD without giving up your hard-won C++ skills. Finally, you'll see how to grow and sustain TDD in your team. Whether you're a complete unit-testing novice or an experienced tester, this book will lead you to mastery of test-driven development in C++. What You Need A C++ compiler running under Windows or Linux, preferably one that supports C++11. Examples presented in the book were built under gcc 4.7.2. Google Mock 1.6 (downloadable for free; it contains Google Test as well) or an alternate C++ unit testing tool. Most examples in the book are written for Google Mock, but it isn't difficult to translate them to your tool of choice. A good programmer's editor or IDE. cmake, preferably. Of course, you can use your own preferred make too. CMakeLists.txt files are provided for each project. Examples provided were built using cmake version 2.8.9. Various freely-available third-party libraries are used as the basis for examples in the book. These include: - cURL- JsonCpp- Boost (filesystem, date_time/gregorian, algorithm, assign)Several examples use the boost headers/libraries. Only one example uses cURL and JsonCpp.
Description : The practice of Test-Driven Development (TDD) has helped thousands of software developers improve quality, agility, productivity, and speed. In Test-Driven Database Development , Max Guernsey, III shows how to adapt TDD to achieve the same powerful benefits in database design and development. Guernsey first explains why TDD offers so much potential to database practitioners, and how to overcome obstacles such as the lack of conventional “testable classes.” You’ll learn how to use “classes of databases” to manage change more effectively; how to define testable database behaviors; how to maximize long-term maintainability by limiting a database’s current scope; and how to use “emergent design” to simplify future expansion. Building on this foundation, the author guides you through implementing modern TDD processes and database refactoring. He presents practical techniques for improving legacy databases; for deviating from strict TDD when necessary; and for adapting TDD to applications that persist data in file systems, XML, or serialized objects. Guernsey shows how to • Build a simple infrastructure to track and standardize scripts and databases • Define a sustainable TDD process for database design • Safely change a design without losing data • Design new databases that are lighter, leaner, simpler, more testable, and easier to change • Reduce design costs by eliminating duplication • Gradually bring the benefits of TDD, agility, and modern design to legacy databases • Remediate errors that find their way into database designs • Isolate behaviors and avoid unwanted dependencies that cause tests to fail With this book as a guide, you will learn how to apply the proven practice of TDD to your database needs, and organize and optimize your organization’s data for a significant competitive advantage. Test-Driven Database Development is the newest title in the highly respected NetObjectives Lean-Agile Series.
Description : Explore the new way of building and maintaining test cases with Java test driven development (TDD) using JUnit 5. This book doesn't just talk about the new concepts, it shows you ways of applying them in TDD and Java 8 to continuously deliver code that excels in all metrics. Unit testing and test driven development have now become part of every developer's skill set. For Java developers, the most popular testing tool has been JUnit, and JUnit 5 is built using the latest features of Java. With Java Unit Testing with JUnit 5, you'll master these new features, including method parameters, extensions, assertions and assumptions, and dynamic tests. You'll also see how to write clean tests with less code. This book is a departure from using older practices and presents new ways of performing tests, building assertions, and injecting dependencies. What You Will Learn Write tests the JUnit 5 way Run your tests from within your IDE Integrate tests with your build and static analysis tools Migrate from JUnit 4 to JUnit 5 Who This Book Is For Java developers both with and without any prior unit testing experience.
Description : Why don't we test our software? Is it because it's expensive? Lengthy? Boring? Automated testing is the solution to all of these problems. Learn how to write a software that tests your software in a fast, cheap and productive manner, increasing your final product's overall quality. In this book you will learn about TDD, one of the most popular agile development practices, using the Java language, but in a way that will allow you to apply the acquired knowledge using any other language. TDD makes the developer to write the test even before the actual code is implemented. This simple inversion on your working routine allows him to write better tested code, with less bugs and better quality. Be professional, test your software!
Description : The World Wide Web has come a long way from static HTML pages. Today's developers enforce and enjoy standards, and we have built the web's primitive tools into advanced libraries, frameworks, and platforms.With these new freedoms come new responsibilities. Developers can now write some amazing bugs. A bug in a web page, hosted in a free web browser, can render expensive servers useless. Modern editors help rapidly write tangled and crufty code, the perfect habitat for bugs of every species, in situations that are hard to debug. We need help from the mortal enemy of the bug: Test-First Programming. This Short Cut seeks fixes for the hardest situation in web development; proactive test cases for Ajax code. We survey existing techniques, and invent new ones. Our goal is heads-down programming, without repeatedly clicking on a web browser.
Description : With the clarity and precision intrinsic to the Test-Driven Development (TDD) process itself, experts James Newkirk and Alexei Vorontsov demonstrate how to implement TDD principles and practices to drive lean, efficient coding—and better design. The best way to understand TDD is to see it in action, and Newkirk and Vorontsov walk step by step through TDD and refactoring in an n-tier, .NET-connected solution. And, as members of the development team for NUnit, a leading unit-testing framework for Microsoft .NET, the authors can offer matchless insights on testing in this environment—ultimately making their expertise your own. Test first—and drive ambiguity out of the development process: Document your code with tests, rather than paper Use test lists to generate explicit requirements and completion criteria Refactor—and improve the design of existing code Alternate programmer tests with customer tests Change how you build UI code—a thin layer on top of rigorously tested code Use tests to make small, incremental changes—and minimize the debugging process Deliver software that’s verifiable, reliable, and robust
Description : Agile methods are gaining more and more interest both in industry and in research. Many industries are transforming their way of working from traditional waterfall projects with long duration to more incremental, iterative and agile practices. At the same time, the need to evaluate and to obtain evidence for different processes, methods and tools has been emphasized. Lech Madeyski offers the first in-depth evaluation of agile methods. He presents in detail the results of three different experiments, including concrete examples of how to conduct statistical analysis with meta analysis or the SPSS package, using as evaluation indicators the number of acceptance tests passed (overall and per hour) and design complexity metrics. The book is appropriate for graduate students, researchers and advanced professionals in software engineering. It proves the real benefits of agile software development, provides readers with in-depth insights into experimental methods in the context of agile development, and discusses various validity threats in empirical studies.
