Testing Ruby With Rspec

Testing Ruby with RSpec

Master the art of test-driven development in Ruby using the popular RSpec Gem. No previous testing experience is needed! About This Video Master the syntax and structure of RSpec, the most popular Ruby Gem for testing Explore the wide collection of RSpec matches available to test your code In Detail This course offers a comprehensive overview of the RSpec testing library for the Ruby programming library. RSpec is the most popular Ruby Gem of all time, with over 300 million downloads to date. If you're new to the topic, testing is the practice of writing code that confirms that other code works as expected. Tests control for regressions, which are changes to the code that break the program. The benefits of testing extend beyond the codebase. Adopting a test-driven approach will also make you a better developer. Tests force you to think critically about a program and its features: classes, objects, methods and more. Testing Ruby with RSpec: The Complete Guide begins with the essentials and proceeds to more complex topics, including: Installation Project initialization Test-Driven Development (TDD) let variables before and after hooks Subjects Shared examples Shared context Built-in matchers Mocks and doubles Instance doubles Class doubles At the completion of this course, you'll have acquired hands-on Ruby testing experience with this awesome RSpec library.

Effective Testing with RSpec 3

"Our tests are broken again!" "Why does the suite take so long to run?" "What value are we getting from these tests anyway?" Solve your testing problems by building and maintaining quality software with RSpec - the popular BDD-flavored Ruby testing framework. This definitive guide from RSpec's lead developer shows you how to use RSpec to drive more maintainable designs, specify and document expected behavior, and prevent regressions during refactoring. Build a project using RSpec to design, describe, and test the behavior of your code. Whether you're new to automated tests or have been using them for years, this book will help you write more effective tests. RSpec has been downloaded more than 100 million times and has inspired countless test frameworks in other languages. Use this influential Ruby testing framework to iteratively develop a project with the confidence that comes from well-tested code. This book guides you through creating a Ruby project with RSpec, and explores the individual components in detail. Start by learning the basics of installing and using RSpec. Then build a real-world JSON API, using RSpec throughout the process to drive a BDD-style outside-in workflow. Apply an effective test strategy to write fast, robust tests that support evolutionary design through refactoring. The rest of the book provides the definitive guide to RSpec's components. Use rspec-core's metadata to slice and dice your spec suite. Dig into rspec-expectations' matchers: compose them in flexible ways, specify expected outcomes with precision, and diagnose problems quickly with the help of good failure messages. Write fast, isolated tests with rspec-mocks' test doubles while pushing your code toward simpler interfaces. The authors, with a combined 20 years of automated testing experience, share testing wisdom that will lead to a fun, productive testing experience. What You Need: To follow along with the book, you'll need Ruby 2.2+. The book will guide you through installing RSpec 3 and setting up a new project to use it.
