If you have worked in a real workshop using a real clamp, you know how valuable they are. It is virtually impossible to shape a piece of metal or wood using a file or a rasp without having the piece in a clamp!
The same thing goes for code. Should you get your code in shape you need to use a clamp and get hold of it first. What is the clamp then, when we are talking code? Well, it isthe test cases, of course!
It is so much easier to change code when you have tests that back up every step you take.
So if you want a mental picture of the great idea of tests, think of a clamp!

Perfekt metafor och gimmic! Amerikaner ser nog inte en tving utan ett kikarsikte – jag gjorde det. Hälsningar, Dag
