Embedded Redis for Spring Boot

You can use an embedded Redis like https://github.com/kstyrc/embedded-redis

1. Add the dependency to your pom.xml

2. Adjust the properties for your integration test to point to your embedded redis, for example :

   spring:
     redis:
       host: localhost
       port: 6379
   

3. Instanciate the embedded redis server in a component that is defined in your tests only :

   @Component
   public class EmbededRedis {
   
       @Value("${spring.redis.port}")
       private int redisPort;
   
       private RedisServer redisServer;
   
       @PostConstruct
       public void startRedis() throws IOException {
           redisServer = new RedisServer(redisPort);
           redisServer.start();
       }
   
       @PreDestroy
       public void stopRedis() {
           redisServer.stop();
       }
   }
   

You can use ozimov/embedded-redis as a Maven(-test)-dependency (this is the successor of kstyrc/embedded-redis).

1. Add the dependency to your pom.xml

   <dependencies>
     ...
     <dependency>
       <groupId>it.ozimov</groupId>
       <artifactId>embedded-redis</artifactId>
       <version>0.7.1</version>
       <scope>test</scope>
     </dependency>
   

2. Adjust your application properties for your integration test

   spring.redis.host=localhost
   spring.redis.port=6379
   

3. Use the embedded redis server in a test configuration

   @TestConfiguration
   public static class EmbededRedisTestConfiguration {
   
     private final redis.embedded.RedisServer redisServer;
   
     public EmbededRedisTestConfiguration(@Value("${spring.redis.port}") final int redisPort) throws IOException {
       this.redisServer = new redis.embedded.RedisServer(redisPort);
     }
   
     @PostConstruct
     public void startRedis() {
       this.redisServer.start();
     }
   
     @PreDestroy
     public void stopRedis() {
       this.redisServer.stop();
     }
   }
