Redis-server

Pure Java implementation redis-server. Embedded redis service when unit testing. You no longer need to Mock redis apis.

1. Support redis api 2.8
2. jedis-3.0+ api is changed, so you must update it to 0.1.0-3.0 if you are using the latest api
3. version 0.2.0 remove jedis dependence, There is no need for any external dependencies.
4. version 0.2.2 support PubSubOperation
5. version 0.2.3 ChannelInputStream to ByteBuffer, it is non blocking.
6. support RESP-3, to connect by HELLO

maven dependency

<dependency>
    <groupId>com.github.microwww</groupId>
    <artifactId>redis-server</artifactId>
    <version>0.3.0</version>
    <scope>test</scope>
</dependency>

Using

    RedisServer server = new RedisServer();
    server.listener("127.0.0.1", 6379); // Redis runs in the background
    InetSocketAddress address = (InetSocketAddress) server.getServerSocket().getLocalSocketAddress();
    logger.info("Redis start :: [{}:{}]", address.getHostName(), address.getPort());

You can set port to 0, server will bind at random port, you can get it by server.getLocalSocketAddress

if you are using spring boot, you can start like this :

    @Bean
    public RedisServer mockRedisServer(RedisProperties redisProperties) throws IOException {
        RedisServer server = new RedisServer();
        server.listener(redisProperties.getHost(), redisProperties.getPort());
        InetSocketAddress address = (InetSocketAddress) server.getServerSocket().getLocalSocketAddress();
        logger.info("Mocker Redis start :: [{}:{}], set 'server.redis.host' to match it", address.getHostName(), address.getPort());
        return server;
    }

server will run with spring config : spring.redis.host, spring.redis.port

A better option is to add dependencies:

<dependency>
    <groupId>com.github.microwww</groupId>
    <artifactId>mocker-redis-spring-boot-starter</artifactId>
    <version>5.3.0</version>
</dependency>

TransactionOperation

Unsupported

If you find unsupported operation, you can add it by yourself, you must implements AbstractOperation add it to server :

server.configScheme(16, new YourOperation1(), ...)

You can add a method, Method signature like this: public void name(RedisRequest request) throws IOException Method name is same as your command, and Method names are all lowercase.

In RedisRequest , you can get RedisServer -> Scheme -> database and so on !

You can create an issue also, I will add it as much as I can.

Good luck !
