<?php

/**
 * assertInstanceOf($expected, $actual[, $message = ''])
 * 
 * Reports an error identified by $message if 
 * $actual is not an instance of $expected.
 * 
 * assertNotInstanceOf() is the inverse of this 
 * assertion and takes the same arguments.
 * 
 * assertAttributeInstanceOf() and assertAttributeNotInstanceOf() are 
 * convenience wrappers that can be applied to a public, 
 * protected, or private attribute of a class or object.
