Book Description

Matt Wynne and Aslak Hellesøy show you how to express your customers’ wild ideas as a set of clear, executable specifications that everyone on the team can read. You’ll learn how to feed those examples into Cucumber and let it guide your development. You’ll build just the right code to keep your customers happy, and not a line more. Although it was born in the Ruby community, you can use Cucumber to test almost any system, from a simple shell script or Perl script, to web applications written in PHP, Java, or any platform.

In Part 1, you’ll get started by using the core features of Cucumber and working with Cucumber’s Gherkin DSL to describe—in plain language—the behavior your customers want from the system. Then you’ll write Ruby code that interprets those plain-language specifications and checks them against your application. If you’re new to Cucumber, this part of the book will teach you everything you need to know to get started.

In Part 2, you’ll consolidate the knowledge you’ve gained with a worked example, where you’ll learn more advanced Cucumber techniques. You’ll also learn how to test asynchronous systems and systems that use a database.

In Part 3, you’ll find a selection of recipes for some of the most difficult and commonly seen situations the authors have helped teams solve. With these patterns and techniques, you’ll learn how to test Ajax-heavy web applications with Capybara and Selenium, REST web services, Ruby on Rails applications, command-line applications, legacy applications, and more.

“Ruby on Rails™ 3 Tutorial: Learn Rails by Example by Michael Hartl has become a must read for developers learning how to build Rails apps.”
—Peter Cooper, Editor of Ruby Inside

Using Rails 3, developers can build web applications of exceptional elegance and power. Although its remarkable capabilities have made Ruby on Rails one of the world’s most popular web development frameworks, it can be challenging to learn and use. Ruby on Rails™ 3 Tutorial is the solution. Leading Rails developer Michael Hartl teaches Rails 3 by guiding you through the development of your own complete sample application using the latest techniques in Rails web development.

Drawing on his experience building RailsSpace, Insoshi, and other sophisticated Rails applications, Hartl illuminates all facets of design and implementation—including powerful new techniques that simplify and accelerate development.

You’ll find integrated tutorials not only for Rails, but also for the essential Ruby, HTML, CSS, JavaScript, and SQL skills you’ll need when developing web applications. Hartl explains how each new technique solves a real-world problem, and he demonstrates this with bite-sized code that’s simple enough to understand, yet novel enough to be useful. Whatever your previous web development experience, this book will guide you to true Rails mastery.

Book Description

Ruby is famous for being easy to learn, but most users only scratch the surface of what it can do. While other books focus on Ruby’s trendier features, The Book of Ruby reveals the secret inner workings of one of the world’s most popular programming languages, teaching you to write clear, maintainable code.

You’ll start with the basics—types, data structures, and control flows—and progress to advanced features like blocks, mixins, metaclasses, and beyond. Rather than bog you down with a lot of theory, The Book of Ruby takes a hands-on approach and focuses on making you productive from day one. As you follow along, you’ll learn to:

• Leverage Ruby’s succinct and flexible syntax to maximize your productivity
• Balance Ruby’s functional, imperative, and object-oriented features
• Write self-modifying programs using dynamic programming techniques
• Create new fibers and threads to manage independent processes concurrently
• Catch and recover from execution errors with robust exception handling
• Develop powerful web applications with the Ruby on Rails framework

Each chapter includes a “Digging Deeper” section that shows you how Ruby works under the hood, so you’ll never be caught off guard by its deceptively simple scoping, multithreading features, or precedence rules.

Book Description

Your Ruby on Rails application is sick. It’s got bugs. Nobody remembers what that tricky piece of code was supposed to do, and nobody can tell what it actually does. Deadlines are looming, but every time you make the slightest change to the code, something else breaks.

You need Test-Driven Development (TDD), a proven process for improving the design, maintainability, and long-term viability of software. In TDD, the tests come first, and then code is written to match the expectation of the test. Using TDD means writing better code faster.

Ruby on Rails has unparalleled support for TDD. In addition to the tools that Rails has built-in, a large and thriving testing community adds new tools at an accelerating rate. Rails Test Prescriptions is your guide to the entire Rails testing ecosystem.

Containing both practical code examples and discussion of why testing works, this book starts with the most basic features delivered as part of core Ruby on Rails. Once you’ve integrated those features into your coding practice, you’ll want to use popular third-party testing tools such as RSpec, Shoulda, Cucumber, Factory Girl, and Rcov. Rails Test Prescriptions will show you how to use these tools and when they are appropriate. Rails Test Prescriptions will cover both the current Rails 2.3.x version as well as the initial 3.0 release.

If you are a Rails programmer who tests code, this book is an invaluable guide to the latest in available testing tools. If you are a Rails programmer who doesn’t test code, then start testing immediately: this book can help. Download Now »
