+Alternatively, to run the tests in JVM mode with Redis Server started as a Docker container, you can run the following command:

+### Running tests in native mode
 
 Additionally, you can generate a native image and run the tests for this native image by adding `-Dnative`:
 
 ```
 mvn clean install -Dtest-redis -Dnative
 ```
+
+You can also use the `-Ddocker` system property (as shown below), if you want the Redis Server container to be started automatically.
+
+```
+mvn clean install -Dtest-redis -Dnative -Ddocker
