 Containers Testing Framework (CTF) is a simple wrapper around [Behave testing framework](http://pythonhosted.org/behave/). Behave is a promising approach for testing containers, since it enables one to focus on describing the behavior of the container from a High Level and in simple English. For more information on how to use Behave and how to write tests using Behave, please refer to the Behave project page.
