🎯 QA Testing Master Guide

Test one small piece of code (like testing if 2+2=4)

Test a single part (like testing a login box)

Test a group of related parts together

Check if different parts talk to each other correctly

Test how systems share data (like a phone charger port)

Make sure systems keep their promises to each other

Check if it does what the business wanted

Your team tests it first (like tasting food before serving)

Real users try it before everyone gets it

Customer checks if they're happy with it

Testing when it's already live (carefully!)
