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 are new to the topic, testing is the practice of writing code that confirms that other code works as expected. Tests control regressions, which are changes to the code that breaks 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.

This course 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 matches, mocks and doubles, instance doubles, and class doubles.

At the completion of this course, you will have acquired hands-on Ruby testing experience with this awesome RSpec library.

short description
In this course, we will master the syntax and structure of RSpec then learn to utilize test-driven development principles to design and implement clean test specs and reduce dependencies in the test suite by mocking objects with class and instance doubles. We will also explore the wide collection of RSpec matches available to test the code.
