Boundary testing

Okay, so let's say you have a toy car that you want to play with. Now, you know that the car moves when you turn it on and push it forward. But what happens when you push it too hard? Or not hard enough?

Boundary testing is like making sure that your toy car works okay, no matter how much you play with it. This means testing the limits or boundaries of what the car can do. Just like you might try to drive the car very slowly or very fast, just to see if it still works right.

Testing the boundaries helps you make sure that the toy car can handle all kinds of situations, no matter how hard or gentle you play with it. And that's important to make sure you can have lots of fun with it, without worrying about it breaking.
