nginx-proxy/test/multiple-ports.bats
Thomas LEVEIL 4bd30f5d2c add test suite. See #197
This test suite is implemented using [bats](https://github.com/sstephenson/bats).

Not all features are tested. For instance ssl features and custom nginx config are missing. Probably others.

This test suite won't work with TravisCI. Too many evenings were wasted trying to overcome [issues](http://stackoverflow.com/questions/32846800/travis-fails-to-stop-docker-containers) that arises only on the TravisCI platform. However it runs on [CircleCI](https://circleci.com) which is also free for opensource projects.
