 * A unit test class to test the MediaScannerService.

 * The media library is found in the /MEDIAS directory.
 * It is composed of 2 musicFolders (Music and Music2) and several little weight audio files.
 *
 * At runtime, the subsonic_home dir is set to target/test-classes/org/libresonic/player/service/mediaScannerServiceTestCase.
 * An empty database is created on the fly.
