Testing Ruby with RSpec The Complete Guide

Testing Ruby with RSpec: The Complete Guide

Master the art of test driven development (TDD) in Ruby using the RSpec Gem. No previous testing experience needed!

Welcome to Testing Ruby with RSpec: The Complete Guide! This course offers a comprehensive overview of the RSpec testing library for the Ruby programming language. 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. Tests give you the confidence to refactor existing code because you know that you will honor the original purpose of the code.

The benefits of testing extend outside of your codebase. In this course, we’ll cover test-driven development (TDD), a methodology in which we write our tests first, before the implementation. Test-driven development often leads to simpler, more decoupled code. Thus, testing can make you a better developer. Tests force you to think critically about the program and its features: the classes, the objects, the methods and more.
