0.31.0 — Native docker healthchecks

docker-compose-rule will now wait for containers to become healthy, as specified in the docker image or in the docker-compose config, before running tests. This allows users to fold their healthchecks into their Docker container specification, letting the team that releases the Docker image determine what makes their service healthy, rather than having each downstream product reinvent the wheel.

Note that you will need to upgrade to at least docker 1.12.0 and docker-compose 1.10.0 to use native healthchecks.
