Running Tests:

Setup

Tox, our test runner, tests against both Python 2.7 and Python 3.4 environments.

If you're using OS X, be sure to use the officially distributed Python 3.4 installer_ since the Homebrew version is missing a necessary library.

Running

Tox will run unit and integration tests in both Python environments using a temporarily created virtualenv.

You should ensure DCOS_CONFIG is set and that the config file points to the Marathon instance you want to use for integration tests.

There are two ways to run tests, you can either use the virtualenv created by make env above:

make test

Or, assuming you have tox installed (via sudo pip install tox):

tox

Other Useful Commands

1. List all of the supported test environments:

   tox --listenvs
   

2. Run a specific set of tests:

   tox -e <testenv>
