Book Description:

Everybody understands why implementing automated tests is important but at the same time developing them can be costly and time consuming, and tests can be also be fragile and prone to false positives. By using Capybara, you can develop robust tests quickly and run them in multiple drivers ensuring greater re-use; Capybara’s API also extends the human readable style made popular by frameworks such as Cucumber and RSpec.

“Application Testing with Capybara” takes you from installing the gem to getting up and running with a Google Search scenario within the first two chapters. We then look deeper into the API, using Rack-Test for applications built with Rails or Sinatra and see how to test handle Asynchronous JavaScript and “black box” components such as Flash. Finally, we consider some advanced topics such as looking at alternatives to Selenium and accessing the native driver directly.

This book takes you from the basics of installing Capybara, through its API and onto advanced topics. You will learn how to use Capybara’s extensive API to interact with your application, covering topics such as navigation, filling in forms, and querying your page for expected content. Beyond this we will consider why Capybara is so well suited to testing applications written in frameworks such as Rails and Sinatra. We will look at strategies for validating seemingly “untestable” components such as HTML5 or Flash by building out a testable API. Finally we will turn you into a Capybara ninja by covering advanced topics such as accessing functionality in the base driver, advanced driver configuration, and alternative flavours of drivers outside Selenium and Rack-Test.

What you will learn from this book

• Install and configure Capybara
• Use Capybara and Cucumber to test scenarios
• Exploit Capybara’s API for interacting with web pages
• Employ Capybara to test Rack applications implemented using Rails or Sinatra
• Handle asynchronous JavaScript
• Apply Capybara to test “black box” components such as Flash or HTML5 Canvas, Audio, and Video
• Practise Capybara outside Cucumber in bespoke frameworks
• Use Capybara with popular Ruby test frameworks
• Explore advanced driver configuration
• Work with alternative drivers such as Capybara-Webkit and Capybara-Mechanize

Book Description:

Rake is a build automation tool written in Ruby. It allows you to specify tasks and describe dependencies as well as group tasks in a namespace. Rake uses Ruby’s anonymous function blocks to define various tasks, allowing the use of the Ruby syntax. Rake’s goal is to automate build processes quickly and expressively.

“Rake Task Management Essentials” is a practical guide that covers the latest techniques in building, testing, and debugging rake tasks to solve real-world automation challenges. The book starts with a basic knowledge of Rake, allowing you to solve repetitive tasks. Then it provides you with information about processes performed with files, which is crucial for understanding the application of the tool. It includes demonstrations to show you how tasks can be run in parallel and how they can be applied in practice. Thereafter, it integrates Rake with Ruby with the help of simple and clear examples. By the end of this book, you will know how Rake has changed the programming world, especially in the Ruby community.

What You Will Learn

• Use the rake command-line tool efficiently
• Learn Rake’s language to write clear custom tasks

Book Description:

The Well-Grounded Rubyist takes you from interested novice to proficient practitioner. It’s a beautifully written tutorial that begins with the basic steps to get your first Ruby program up and running and goes on to explore sophisticated topics like callable objects, reflection, and threading. Whether the topic is simple or tough, the book’s easy-to-follow examples and explanations will give you immediate confidence as you build your Ruby programming skills.
The Well-Grounded Rubyist is a thoroughly revised and updated edition of the best-selling Ruby for Rails. In this new book, expert author David A. Black moves beyond Rails and presents a broader view of Ruby. It covers Ruby 1.9, and keeps the same sharp focus and clear writing that made Ruby for Rails stand out.
Starting with the basics, The Well-Grounded Rubyist explains Ruby objects and their interactions from the ground up. In the middle chapters, the book turns to an examination of Ruby’s built-in, core classes, showing the reader how to manipulate strings, numbers, arrays, ranges, hashes, sets, and more. Regular expressions get attention, as do file and other I/O operations.
Along the way, the reader is introduced to numerous tools included in the standard Ruby distribution–tools like the task manager Rake and the interactive Ruby console-based interpreter Irb–that facilitate Ruby development and make it an integrated and pleasant experience.
The book encompasses advanced topics, like the design of Ruby’s class and module system, and the use of Ruby threads, taking even the new Rubyist deep into the language and giving every reader the foundations necessary to use, explore, and enjoy this unusually popular and versatile language.
It’s no wonder one reader commented: “The technical depth is just right to not distract beginners, yet detailed enough for more advanced readers.”

What You’ll Learn

Book Description:

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.
