What is Unit Test?

A test that checks if a small piece of code works correctly in isolation

Why It Matters

Unit tests catch bugs quickly and make it safer to change code without breaking things

A test that verifies your calculateTotal function correctly adds items and applies discounts

A test that checks if multiple parts of your system work correctly together

End-to-end test that simulates a real user completing tasks in your application

Verifying that your code works correctly through automated checks
