Development testing

Development testing is like playing a game of pretend with your toys before you invite your friends to come play with you. Just like how you try out different ideas and scenarios in your pretend game to see what works and what doesn't, developers do this too with their computer programs.

Instead of using toys, developers use a special tool called a testing framework to pretend to be a user and test if their program works correctly. They test different parts of the program, making sure everything is working well before they give it to other people to use. It's kind of like practicing a song before singing it in front of an audience.

This helps developers catch any errors or bugs that might stop the program from working properly. By testing everything beforehand, they can make sure the program is safe and reliable for others to use without any unwanted surprises.
