 51    * This class allows you to specify the order that test methods will execute in
 52    * and yet still retain the ability to have test methods found via reflection.<p>
 53    *
 54    * Generally, when you want to specify the order that tests will be run, you write
 55    * code that looks like this.
 56    * <pre>
 57    * public static Test suite() {
 58    * final TestSuite suite = new TestSuite();
 59    * suite.addTest( new FooTest("testOne") );
 60    * suite.addTest( new FooTest("testTwo") );
 61    * return suite;
 62    * }
 63    * </pre>
 64    * The problem with this approach is that when testThree() is written, if it isn't
 65    * added to the suite method, it won't get executed.<p>
 66    *
 67    * Using OrderedTestSuite, you write code like this:
 68    * <pre>
 69    * public static Test suite() {
 70    * return new OrderedTestSuite(FooTest.class, new String[]{"testOne", "testTwo"});
 71    * }
 72    * </pre>
 73    * testOne() and testTwo() will be executed in order just as in the first example. The
 74    * difference is that OrderedTestSuite will use reflection to find other methods starting
 75    * with test and will execute them. This means that if you write testThree but forget to
 76    * add it to suite() then it will still get executed, albeit not in a defined order.
