Gray-box testing

Gray-box testing is like playing hide and seek with a friend who gives you a clue about where they're hiding.

When you're playing hide and seek, sometimes your friend will say "I'm hiding in a room with a red door." This is like gray-box testing because it's a mix between black-box testing (when your friend doesn't give any clues about where they're hiding) and white-box testing (when your friend tells you exactly where they're hiding).

In gray-box testing, the person doing the testing (like a software tester) has some information about how the program works, but not all the juicy details. This can include things like knowing how the program is supposed to behave, or having access to some of the code.

By having this information, the tester can do a better job of finding bugs or problems with the program. It's like having a map while playing hide and seek - you'll be more likely to find your friend if you know where they're likely to be hiding.

Overall, gray-box testing is a helpful tool for making sure that programs are working correctly - kind of like how playing hide and seek with clues can help you find your friend faster!
