 *  All variants of argument values are placed in <code>parameters</code> array.
 *  Also, this array contains an expected return value for every pair of
 *  arguments values: <br>
 *      <code>null</code> - return value of <code>concreteMethodByName()</code><br> is
 *  <code>null</code>
 *      <code>"T"</code> - return value of <code>concreteMethodByName()</code><br> is not
