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. We’ll be using the Ruby programming language and the Ruby on Rails web framework to build everything. These are the best tools for the job, in my opinion. Ruby is a very expressive and powerful programming language, and Ruby on Rails is a very powerful web framework. We’ll use the test-driven development (TDD) style of software design and engineering, which means we’ll write failing tests first and only then write our implementation code to get our failing tests passing. We’ll use the RSpec testing framework to write our tests. RSpec describes itself as a tool for performing “behavior-driven development” and is in fact the best tool available for testing Ruby code. If you’ve never used RSpec before, don’t worry; in this book, I’ll cover more than enough to get you started and productive. We will use the PostgreSQL relational database management system (RDBMS) to store our project’s data. 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.

Sidekiq is a reliable, well-supported, high-performing way to run code in the background of any Rails app. This book will give you a solid, practical foundation for creating resilient, well-tested, self-healing code that uses background jobs. You'll be able to simulate real-world failure modes and learn how to write idempotent code that can be safely run with Sidekiq. Whether you need to offload slow code out of a controller action, or make a flaky API call more fault tolerant, Sidekiq is the way to do that. One of the best ways to improve your Rails app's performance is to use background jobs with Sidekiq. While Sidekiq is easy to get set up, you need to do more than just move code around to reap the benefits. In this book, you'll get solutions to what sort of code should go into a Sidekiq job and how to manage those jobs. Even though you just need a few lines of code to run a Sidekiq job, there is quite a bit of complexity hiding in the shadows. A Rails app with Sidekiq jobs is really a distributed system. It has all the same challenges as a massive microservices-based architecture.

The Rails 7 Way is the comprehensive, authoritative reference guide for professionals delivering production-quality code using modern Ruby on Rails. It illuminates the entire Rails 7 API, its most powerful idioms, design approaches, and libraries. Building on the previous editions, this edition has been heavily refactored and updated. It features entirely new chapters on Action Mailbox, Active Storage, asset pipelines, ViewComponent, and Turbo. Through detailed code examples, you’ll dive deep into Ruby on Rails, discover why it’s designed as it is, and learn to make it do exactly what you want. Proven in thousands of production systems, the knowledge in this book will maximize your productivity and help you build more successful solutions. Rails 7 is also a significant change for javascript in Rails: From a new approach to the asset pipeline (without Node by default and offering a wide range of choices) to replacing Turbolinks and UJS with Turbo and Stimulus. The new autoloader Zeitwerk introduced in Rails 6 as an option now is the only choice. To make the most out of this book, you should be at least somewhat familiar with how to bootstrap a Rails application and the MVC (Model-View-Controller) architectural pattern.

This self-study course written as a book is your first step towards making money by coding and programming from home, and doing that with fun. You will understand how the Ruby language works, and establish a foundation for being successful freelance developer. From the author’s personal point of view, Ruby is a good tool for doing something of my own - some project of mine, a program which can be shared with others, attract attention or earn money. In other words, Ruby is an efficient and interesting language, not only for work but for its own sake too. As stated earlier, there are many trends in software development. Each trend is unique and requires its own know-how. The author believes that there are currently at least two “tried and tested” trends in programming which give the maximum result in the minimum time. “Results” here means both cash compensation and knowing how to do something with your own hands. The first is mobile development – programs for mobile phones (Android, iPhone), tablets (iPad) and other devices. The second is web programming (or web development).
