Box Test

The Locked Box Test is an informal guideline used to determine an object's most appropriate Object Class. It goes like this:


 * If you lock it in a box, leave it alone, and nothing bad will happen, then it's probably Safe.
 * If you lock it in a box, leave it alone, and you're not entirely sure what will happen, then it's probably Euclid.
 * If you lock it in a box, leave it alone, and it easily escapes, then it's probably Keter.
 * If it is the box, then it's probably Thaumiel.
