“Ever wonder how developers catch bugs before they become big problems?
That’s where Unit Tests come in.

A unit test is a small piece of code that checks if another small piece of code — like a function or method — works the way it’s supposed to.

Think of it like a mini quality check for each building block of your software.

By testing units in isolation, developers can spot mistakes early, refactor with confidence, and keep the codebase strong.

In short — unit tests save time, catch bugs, and help build better software.

So next time you see clean, reliable code — thank unit testing!”
