Okay kiddo, let me explain package testing in a way that you can easily understand. Imagine that you love playing with your toys and you have a new toy that you want to open and play with. But before you can start playing, you have to make sure the toy is safe and works properly, right? So you have to check the package for any damage or defects before opening it up.
The same thing goes with package testing. When companies create products, they put them in packages to protect them and to make sure they stay safe during transportation. But before they send out the packages, they have to test them to make sure they are strong enough to protect the product inside.
Package testing can involve a lot of different things, like dropping the package from a high place to see if it breaks, freezing it to see if it cracks, or even shaking it to make sure nothing inside gets damaged. All these tests help companies make sure that their product package can keep the product safe no matter what happens during shipping.
So, just like you inspect your toys before playing with them, companies inspect their product packages before sending them out to stores or customers. This way, they can make sure that their product arrives safely to your doorstep without any damage.
