/**
 * @assertion The result of a lookup of method m in class C with respect to
 * library L is: If C declares a concrete instance method named m that is
 * accessible to L, then that method is the result of the lookup. Otherwise,
 * if C has a superclass S, then the result of the lookup is the result of
 * looking up m in S with respect to L. Otherwise, we say that the method
 * lookup has failed.
 * @description Checks that if there is no method m in class C but class C
 * has a superclass S,then the result of the lookup is the result of
 * looking up m in S
