Description

Welcome to Testing Ruby with RSpec: The Complete Guide!

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 outside of the codebase. Adopting a test-driven approach will also 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.

Testing Ruby with RSpec 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
