Tests Enable of Fearless Refactoring

In the world of software development, change is inevitable. As systems grow and evolve, so too must the code that powers them. This is where refactoring comes into play – the art of restructuring existing code without changing its external behavior. However, refactoring can be a daunting task, fraught with the risk of introducing new bugs or breaking existing functionality. This is where tests become invaluable, serving as the safety net that enables fearless refactoring.
