Redis-Mock

Redis Mock is a simple in-memory mock of redis for java testing. It allows you to test any behaviour dependent on redis without having to deploy an instance of redis

Quickstart

Add it as a dependency in Maven as:

<dependency>
  <groupId>ai.grakn</groupId>
  <artifactId>redis-mock</artifactId>
  <version>0.1-SNAPSHOT</version>
</dependency>

<repositories>
    <repository>
        <id>releases</id>
        <url>https://maven.grakn.ai/content/repositories/releases/</url>
    </repository>
</repositories>

Create a redis server and bind it to jedis:

private static RedisServer server = null;

@Before
public void before() throws IOException {
  server = RedisServer.newRedisServer();  // bind to a random port
  server.start();
}

@Test
public void test() {
  ...
  Jedis jedis = new Jedis(server.getHost(), server.getBindPort());
  ...
}

@After
public void after() {
  server.stop();
  server = null;
}

From here test as needed

Master and Slave

RedisServer master = newRedisServer();
RedisServer slave = newRedisServer();
master.setSlave(slave);

Fault tolerance testing

We can make a RedisServer close connection after every serveral commands. This will cause a connection exception for clients.

RedisServer server = RedisServer.newRedisServer();
ServiceOptions options = new ServiceOptions();
options.setCloseSocketAfterSeveralCommands(3);
server.setOptions(options);
server.start();
