Define an integration test API for collaborating blended container(s) using docker as a runtime for the container(s) under test and an Akka based Camel framework to perform the integration tests as pure blackbox tests. Container(s) may be prestarted and discovered (for execution speed) or started by the integration test (for reproducability).
