Imagine you have a bunch of friends and you want to give each of them a turn to play your favorite game. But you don't want to forget who you already let play and who still needs a turn. That's where the round robin test comes in!
A round robin test is like a game schedule where each person gets a turn to play in a certain order. For example, if you have 4 friends, you can put their names in a list and start with the first person in the list. They get to play the game first. Then you go to the second person, the third person, and finally the fourth person. Once you reach the end of the list, you start over at the beginning and keep going until everyone has had a turn.
This is useful for things like testing different versions of software or checking the accuracy of measurements. Instead of randomly selecting who gets to participate, you can use a round robin test to make sure everyone gets a turn and you don't miss anyone. It's like taking turns on the playground!
