/**
 * @assertion Evaluation of a conditional expression c of the form e1 ? e2 : e3
 * proceeds as follows:
 * First, e1 is evaluated to an object o1. Then, o1 is subjected to boolean
 * conversion producing an object r. If r is true, then the value of c is the
 * result of evaluating the expression e2. Otherwise the value of c is the
 * result of evaluating the expression e3.
 * @description Checks that a conditional expression is evaluated correctly.
