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.

# The Standard Library is a collection of test helpers intended to
|
||||
# simplify testing. It contains the following types of test helpers.
|
||||
#
|
||||
# - Assertions are functions that perform a test and output relevant
|
||||
# information on failure to help debugging. They return 1 on failure
|
||||
# and 0 otherwise.
|
||||
#
|
||||
# All output is formatted for readability using the functions of
|
||||
# `output.bash' and sent to the standard error.
