 * Base class for tests.
 * The tests focuse on that LoggerFinder works well in jigsaw environment,
 * i.e. make sure correct Logger can be retrieved,
 * also verify that basic functionality of retrieved Logger's works well.
 *
 * Note: As the test will take long time, to avoid timeout,
 * split it as several tests, this class is the base class for tests.
