For integration testing, two test methods HelloWorld and RedisTest were implemented in c++ library and tested in test.mq4. you can just simply delete them.
The HelloWorld method is defined to return a string from c++ library as same as what input parameter string is.
And RedisTest method is defined to check availability of Redis server, which connect to a exist server and do nothing.

In this library, we use a light library hiredis [url:https://github.com/redis/hiredis] as client for Redis.
Methods end with WithTimeout were implemented to call redisConnectWithTimeout in order to check connection healthy before redisCommand is called.
In hiredis, the default timeout parameter is 1000ms, this might cause timeout error when Redis connection situation is bad.

1.Use RedisGet and RedisCommand when Redis server is located in your intranet.
2.Correspondingly, Use RedisGetWithTimeout and RedisCommandTimeout when Redis server connection healthy/availability is not good.

Use EXPIRE and EXPIREAT command if you want to set an EXPIREable value.
