    ShardedLoggerBackend slb = new ShardedLoggerBackend(shards, mapper);
    when(mapper.getShardNumber(anyString(), eq("34/df/file1"), any(byte[].class))).thenReturn(34);
    when(mapper.getShardNumber(anyString(), eq("142/345/file1"), any(byte[].class))).thenReturn(142);
    slb.log("localhost", "34/df/file1", "line1");
    slb.log("localhost", "142/345/file1", "line2");
    verify(log1).log("localhost", "34/df/file1", "line1\n".getBytes(), 0, "line1\n".getBytes().length);
    verify(log2).log("localhost", "142/345/file1", "line2\n".getBytes(), 0, "line2\n".getBytes().length);
}
