+    Integration test demo with wait configurations mapped from Docker compose depends_on long syntax
+  
+    Call it with: 'mvn verify'
+  
+    The test does the following:
+  
+    * Builds a custom postgres image with a healtcheck (because we do not support adding healthchecks from compose yet)
+    * Start an init container printing a message
+    * When successfully exited, database container starts
+    * Once Postgres enters state healthy, another simple container printing a message is started
+    * Stops and removes the containers.
