+ *  This LiveTest requires:
+ *  1- The 'spring-cloud-bus/spring-cloud-config-server' service running, with valid Spring Cloud Config properties, for instance:
+ *    1.1- `spring.cloud.config.server.git.uri` pointing to a valid URI, which has `user.role` and `user.password` properties configured in a properties file. For example, to achieve this in a dev environment:
+ *      1.1.1- `cd my/custom/path`
+ *      1.1.2- `git init .`
+ *      1.1.3- `echo user.role=Programmer >> application.properties`
+ *      1.1.4- `echo user.password=d3v3L >> application.properties`
+ *      1.1.5- `git add .`
+ *      1.1.6- `git commit -m 'inital commit'`
+ *      1.1.7- 'spring-cloud-bus/spring-cloud-config-server' with property `spring.cloud.config.server.git.uri=my/custom/path`
+ *  
+ *  Note: This is enough to run the ContextTest successfully, but to get the full functionality shown in the related article, we'll need also a RabbitMQ instance running (e.g. `docker run -d --hostname my-rabbit --name some-rabbit -p 15672:15672 -p 5672:5672 rabbitmq:3-management`)
