What is Testing?

Verifying that your code works correctly through automated checks

Why It Matters

Testing catches bugs early, prevents regressions, and gives confidence to make changes

Real-World Example

Running a test suite before deploying to ensure nothing is broken

“Understanding terms like Testing matters because it helps you have better conversations with developers and make smarter decisions about your software. You do not need to be technical. You just need to know enough to ask the right questions.”
