/**
 * A TestSuite is a composite of Tests. It runs a collection of test cases.
 *
 * Here is an example using the dynamic test definition.
 *
 * <code>
 * <?php
 * $suite = new PHPUnit2_Framework_TestSuite;
 * $suite->addTest(new MathTest('testPass'));
 * ?>
 * </code>
 *
 * Alternatively, a TestSuite can extract the tests to be run automatically.
 * To do so you pass a ReflectionClass instance for your
 * PHPUnit2_Framework_TestCase class to the PHPUnit2_Framework_TestSuite
 * constructor.
 *
 * <code>
 * <?php
 * $suite = new PHPUnit2_Framework_TestSuite(
 *   new ReflectionClass('MathTest')
 * );
 * ?>
 * </code>
 *
 * This constructor creates a suite with all the methods starting with
 * "test" that take no arguments.
