Unit testing is a critical practice in software development that ensures individual components of your code work as expected. Here's a concise overview to get you started:

Why Unit Testing Matters ✅

  • Early Bug Detection: Identify issues at the development stage, reducing fixing costs later.
  • Code Confidence: Verify that changes don’t break existing functionality.
  • Documentation: Serve as living documentation for your code’s behavior.

Popular Tools & Frameworks 🛠️

  • JUnit (Java):
