/**
 * <p>
 *  Test Case for the BeanUtils class.  The majority of these tests use
 *  instances of the TestBean class, so be sure to update the tests if you
 *  change the characteristics of that class.

 *
 * <p>
 *  Template for this stolen from Craigs PropertyUtilsTestCase
 * </p>
 *
 * <p>
 *   Note that the tests are dependant upon the static aspects
 *   (such as array sizes...) of the TestBean.java class, so ensure
 *   than all changes to TestBean are reflected here.
 * </p>
 *
 * <p>
 *  So far, this test case has tests for the following methods of the
 *  <code>BeanUtils</code> class:
 * </p>
 * <ul>
 *   <li>getArrayProperty(Object bean, String name)</li>
 * </ul>
