If you're not familiar with the subject, testing is the act that involves "writing code that confirms that other code works as expected." Tests check for the possibility of regression, a change made to code that breaks the program. Tests allow you to feel confident in modifying existing code since you are confident that you will keep the original intention in the original code.
The benefits of testing go beyond your code base. We'll explore the concept of test-driven development (TDD), a method that requires us to create our test scripts first before we implement them. Test-driven development usually leads to simpler, separated code, and testing can help you become a better designer. Tests require you to think critically about the program and its capabilities, including the classes, the objects, the methods, and more.
Testing Ruby using RSpec starts with the RSpec basics and moves to more complicated topics like:
