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