    * Creates a test suite whose file organization matches an expected structure.
    * To use this, your suite should look like:

    *     dart/

    *         to/
    *           mytestsuite/

+   *             example2_test.dart
+   *             example3_test.dart

    * The important parts:
    *
    * * The leaf directory name is the name of your test suite.
    * * The status file uses the same name.
-   * * Test files are directly in that directory and end in "_tests.dart".
+   * * Test files are directly in that directory and end in "_test.dart".

    * If you follow that convention, then you can construct one of these like:
    *
    * new StandardTestSuite.forDirectory(configuration, 'path/to/mytestsuite');
    *
    * instead of having to create a custom [StandardTestSuite] subclass. In
    * particular, if you add 'path/to/mytestsuite' to [TEST_SUITE_DIRECTORIES]
    * in test.dart, this will all be set up for you.
