Forcing Redis to Timeout

Question

I am trying to force my redis client to timeout for testing purpose and I a fail to achieve so. I specify timeout to 2ms in my config and the set operation I perform takes > 2ms so why it does not timeout? Are these settings are kind of soft settings and not hard enforcement? I am using Jedis 2.6 and Scala 2.10 with Play 2.2.3

@Singleton
class RedisClient extends Cache {

  // set timeout
  val TIMEOUT = 2
  private val pool = new JedisPool(new JedisPoolConfig(), getStringFromConfig("redis.url"), getIntFromConfig("redis.port"), TIMEOUT);

  def isOpen = pool.getNumActive()

  def set(key: String, value: String) = {
    isOpen match {
      case -1 => throw new Exception("Redis server is not running")
      case _ => {
        val jedis = pool.getResource()
        val before = Platform.currentTime
        jedis.set(key, value)
        println("TIME TAKEN " + (Platform.currentTime - before))
        pool.returnResource(jedis)
      }
    }
  }
}

Actualy you do not need to test it but you may found answer in Jedis sources. TimeOut value used:

as java socket connection timeout
as SO_TIMEOUT value. More info about it here.

To achieve goal in your test:

Redis server should be heavy loaded during your test to not accept the connection. If you need connection timeout.
Try to use some proxy to drop down connection perfomance (timeout by SO_TIMEOUT value).
