Learn to properly test Ruby and Ruby on Rails applications by first writing failing tests, and then by implementing application code to make the failing tests pass. This book will teach you how to employ test-driven development (TDD) using RSpec while building a blog from start to finish. By the end of the book, you will be ready to deploy their fully tested blog to their own production web server using the latest versions of Ruby 3 and Ruby on Rails 7. The biggest challenge with learning and becoming comfortable with test-driven development is that software engineers often cannot imagine what writing a failing test looks like in practice. They write their implementation code first, and only then think about writing tests around their implementation code. This leads to tests that pass by accident, or tests that do not actually test anything. This book will give you the confidence to write tests in the RSpec domain-specific language. You will see your tests fail "properly" before proceeding with writing any implementation code to get them to pass. This book covers the latest techniques for writing RSpec tests, including "system" specs, and the often overlooked "view" specs, and how to integrate RSpec with other tools like Capybara, headless Chrome, and the new web driver gem. It also covers FactoryBot for mock test data and offers experienced advice on how to avoid creating tests that fail randomly. What You Will Learn Build a blog application from start to finish using test driven development Install and explore popular tools used in professional Ruby software engineering Evaluate the benefits of effective testing in RSpec Explore Capistrano for advanced user interface testing Who Is This Book For Beginner to intermediate Ruby software engineers who are interested in learning to use TDD with RSpec to test and build web applications using Ruby on Rails. Readers should have some basic experience with Ruby and Ruby on Rails and have read the "Getting Started with Rails" guide, or something similar.

Ruby on Rails ist eines der beliebtesten Frameworks im Bereich der Webentwicklung. Einer der Hauptgründe dafür ist die geringe Einarbeitungszeit, da das Model-View-Controller-Konzept (MVC) klar zu erkennen ist. Ruby on Rails gibt uns sehr schnell Feedback über das Ergebnis unserer Arbeit, wodurch die Entwicklung von Webanwendungen sehr viel Spaß mit sich bringt. Ruby on Rails wurde von David Heinemeier Hansson bei der Entwicklung von Basecamp extrahiert und erblickte im Juli 2004 das Licht der Open-Source-Welt. Mit der Zeit hat sich eine gigantische Community und ein Core Team, welches die Entwicklung koordiniert, um das Projekt gebildet. Ruby on Rails wird mit der Version 3 erwachsen und fit für den Enterprise Bereich. Den Autoren Michael Voigt und Stefan Tennigkeit - selbst Ruby-Entwickler - gelang es, das komplexe Themengebiet unter dem Aspekt der praktischen Umsetzung in verständlicher Art und Weise zu beschreiben. Das eigene Fachwissen sowie die persönlichen Erfahrungen der Autoren im Umgang mit Ruby on Rails werden durch zahlreiche Abbildungen, Tabellen und Quelltext-Beispiele einer produktiv gestellten Webanwendung (kraeftemessen.com) ergänzt. Durch diese deutliche Praxisorientierung schaffen es die Autoren anhand von alltagspraktischen Anwendungsfällen, Themen wie beispielsweise HAML und SASS, Release- und Sourcecode-Management mit Capistrano, Test Driven Development, Volltextsuche mit Sphinx, Geokoordinaten inhaltlich und methodisch zu verdeutlichen.

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.

Ruby in Practice increases your productivity by showing you specific Ruby techniques you can use in your projects. The book offers detailed strategies for using Ruby in a large-scale environment. You'll see concrete examples of integration, messaging, web development, and databases, all presented in a clear Problem/Solution format. This book won't help you push your deadline back, but it will help you get the job done in less time. Above all, Ruby in Practice is a practical book for developers who want an in depth understanding of the Ruby language and its toolset. The book is divided into three major parts. The first part concentrates on issues that developers face both from within their organizations and from their peers. The authors weigh the costs and benefits of using Ruby in enterprise development projects, the over-riding theme being that every developer should always aim to use the right tool for any particular job. The authors then examine the pros and cons of developing with Ruby, and where appropriate, compare Ruby to other languages, both conceptually and in code. The second part discusses techniques for communication and integration of systems. The authors describe how libraries and techniques are used to facilitate messaging, web development and communication automation. They also focus on how the strategies in the first section can be used with these libraries to make development more flexible and efficient. The last part shows how to manage data and integrate with existing data using Ruby. The authors describe techniques for using existing Ruby libraries that either replace popular Java libraries or can interface with existing data in a different way. They go on to show you how strategies covered in the first section can be used to enable Ruby to interact with existing assets or to build new data systems. Purchase of the print book comes with an offer of a free PDF, ePub, and Kindle eBook from Manning. Also available is all code from the book.

Quite simply, test-driven development is meant to eliminate fear in application development. While some fear is healthy (often viewed as a conscience that tells programmers to "be careful!"), the author believes that byproducts of fear include tentative, grumpy, and uncommunicative programmers who are unable to absorb constructive criticism. When programming teams buy into TDD, they immediately see positive results. They eliminate the fear involved in their jobs, and are better equipped to tackle the difficult challenges that face them. TDD eliminates tentative traits, it teaches programmers to communicate, and it encourages team members to seek out criticism However, even the author admits that grumpiness must be worked out individually! In short, the premise behind TDD is that code should be continually tested and refactored. Kent Beck teaches programmers by example, so they can painlessly and dramatically increase the quality of their work.
