assertThrows

Write assertThrows(fn, errClass, msgPart) — call fn(); if it does NOT throw, fail (return "no-throw"). If it throws the wrong error class, return "wrong-type". If errClass is given and msgPart is given, the error message must contain msgPart, else return "wrong-message". On full success return "ok".
