### Question:
VolumeUtils { public static String getLogVolume(String directory) { return getVolumeDir(FIRST_VOLUME, VOLUME_PREFIX, directory); } private  VolumeUtils(); static String buildVolumePathString(int volumeCount, String directory); static String buildVolumePathStringZeroVolumeHandled(int volumeCount, String directory); static String buildSingleVolumePath(int volumeCount, String directory); static String buildSingleVolumePath(int volumeIndex, int volumeCount, String directory); static String getLogVolume(String directory); static String buildVolumePathFromVolumeIndexZeroVolumeHandled(int startIndex, int volumeCount, String directory); static long convertGBToBytes(int sizeInGb); static final String VOLUME_PREFIX; static final String ROOT_VOLUME_PREFIX; }### Answer:
@Test public void testGetLogVolume() { String directories = VolumeUtils.getLogVolume("test"); assertEquals("/hadoopfs/fs1/test", directories); }
