Model-based testing

Model-based testing is like a game where you have to follow certain rules to win. In this game, you have a plan or a blueprint called a "model" that tells you which steps to take to win. Imagine you are playing with building blocks and your model tells you which blocks to use, where to put them and how many to add.

In model-based testing, the model is like your plan for testing a program. The program is like a building made of blocks and you are the tester who wants to make sure it's strong and sturdy. Your job is to test the program by following the steps in the model.

To do this, you use special tools that help you follow each step in the model and make sure everything is working correctly. Just like you test your building blocks to make sure they fit properly and don't fall down, you test the program to make sure it's working correctly and doesn't crash.

Overall, model-based testing is a systematic way of testing that uses a plan or a blueprint to make sure a program works correctly. It's like a game where you have rules to follow and tools to help you make sure everything is working as it should be.
