Maintenance testing

Okay, kiddo, have you ever had a toy that stopped working and needed to be fixed? Well, just like toys, buildings, machines, and other things need to be checked once in a while to make sure they're working okay. This is called maintenance testing.

Say you have a bike. To make sure your bike stays safe for you to ride, you need to do things like check the brakes, oil the chain, and inflate the tires. Maintenance testing is like that, but for really big things like buildings, airplanes, and power plants.

People who work in maintenance testing make sure that these big things are working right and won't break down. Imagine if an airplane didn't get checked properly and something went wrong while it was flying! That would be really dangerous!

So, maintenance testing is like taking good care of things so that they stay safe and work properly. Just like how we take care of our toys and bikes!
