What is RSpec testing?

RSpec testing is a framework for writing and executing tests in Ruby applications, particularly those built with Ruby on Rails. It encourages a behavior-driven development (BDD) approach, allowing developers to write readable and expressive tests that describe the expected behavior of their code. RSpec helps ensure code quality, catch bugs early, and make refactoring safer by providing immediate feedback when something breaks. It's widely used in the Ruby community due to its flexibility and clear syntax.
