 * @assertion int hashCode
 * Get a hash code for this object.
 *
 * All objects have hash codes. Hash codes are guaranteed to be the same for
 * objects that are equal when compared using the equality operator ==. Other
 * than that there are no guarantees about the hash codes. They will not be
 * consistent between runs and there are no distribution guarantees.
 *
 * @description Checks that hash code is the same during execution of the test,
 * because object is equal to itself
