Added unit test:
@test
public void testMurmurSharding() throws Exception {
List shards = new ArrayList(3);
shards.add(new JedisShardInfo("localhost", Protocol.DEFAULT_PORT));
shards.add(new JedisShardInfo("localhost", Protocol.DEFAULT_PORT + 1));
shards.add(new JedisShardInfo("localhost", Protocol.DEFAULT_PORT + 2));
Sharded<Jedis, JedisShardInfo> sharded = new Sharded<Jedis, JedisShardInfo>(shards,
Hashing.MURMUR_HASH);
int shard_6379 = 0;
int shard_6380 = 0;
int shard_6381 = 0;
for (int i = 0; i < 1000; i++) {
JedisShardInfo jedisShardInfo = sharded.getShardInfo(Integer.toString(i));
switch (jedisShardInfo.getPort()) {
case 6379:
shard_6379++;
break;
case 6380:
shard_6380++;
break;
case 6381:
shard_6381++;
break;
default:
fail("Attempting to use a non-defined shard!!:" + jedisShardInfo);
break;
}
// System.out.println("key=" + i + " shard=" + sharded.getShardInfo(Integer.toString(i)));
}
System.out.println("6379:" + shard_6379);
System.out.println("6380:" + shard_6380);
System.out.println("6381:" + shard_6381);
assertTrue(shard_6379 > 300 && shard_6379 < 400);
assertTrue(shard_6380 > 300 && shard_6380 < 400);
assertTrue(shard_6381 > 300 && shard_6381 < 400);
}
