Testing support

This crate provides utilities for testing Redis clients and applications:

• Mock Connections: MockRedisConnection implements ConnectionLike and can be used in the same place as any other type that behaves like a Redis connection. This is useful for writing unit tests without needing a real Redis server.
• Standalone Servers: server::RedisServer provides an easy way to spin up and manage a real local Redis instance for integration tests.
• Clusters: cluster::RedisCluster provides functionality to spawn and configure a local Redis cluster with multiple nodes and replicas.
• Sentinels: sentinel::RedisSentinelCluster provides functionality to spawn and configure a local Redis sentinel cluster.

Example (Mock Connection)

use redis::{ConnectionLike, RedisError};
use redis_test::{MockCmd, MockRedisConnection};

fn my_exists<C: ConnectionLike>(conn: &mut C, key: &str) -> Result<bool, RedisError> {
    let exists: bool = redis::cmd("EXISTS").arg(key).query(conn)?;
    Ok(exists)
}

let mut mock_connection = MockRedisConnection::new(vec![
    MockCmd::new(redis::cmd("EXISTS").arg("foo"), Ok("1")),
]);

let result = my_exists(&mut mock_connection, "foo").unwrap();
assert_eq!(result, true);
