Fake-Jedis

Simple Java library that mimics the behavior of a redis server wrapped into a Jedis instance. Its purpose is to test algorithms involving the use of a redis database without starting an instance.

Important note: You should NEVER use fake-jedis in a production or a performance testing context. It is designed to test your algorithms but won't behave as a real redis instance when you'll test concurrency, load, persistence, etc.

Installation

Add the dependency to your maven project (or checkout the project and compile the jar).

<dependency>
  <groupId>com.vdurmont</groupId>
  <artifactId>fake-jedis</artifactId>
  <version>0.1.0</version>
  <scope>test</scope> <!-- You should not use Fake-Jedis if it is not a test! -->
<dependency>

Usage

Simply instantiate a FakeJedis and use it as a regular Jedis client.

Jedis jedis = new FakeJedis();
// Use your client
jedis.lpush("my_key", "my_value");
Long len = jedis.llen("my_key");

Do not hesitate to take a look at the Jedis documentation and/or the Redis documentation.
