 ## Running tests
 
-We use [Nose](http://readthedocs.org/docs/nose/) as a test runner. Make sure it
-is installed along with other test dependencies:
+This section covers how to run tests for the root of this repo, running tests 
+for the oo-install wrapper is described in [utils/README.md](utils/README.md).
+
+We use [tox](http://readthedocs.org/docs/tox/) to manage virtualenvs and run
+tests. Alternatively, tests can be run using
+[detox](https://pypi.python.org/pypi/detox/) which allows for running tests in
+parallel
+
 
 ```
-pip install -r utils/test-requirements.txt
+pip install tox detox
 ```
 
-Run the tests with:
+List the test environments available:
+```
+tox -l

+
+Run all of the tests with:
+```
+tox

+
+Run all of the tests in parallel with detox:

+Running a particular test environment (python 2.7 flake8 tests in this case):
+```
+tox -e py27-ansible22-flake8

+
+Running a particular test environment in a clean virtualenv (python 3.5 pylint
+tests in this case):
+```
+tox -r -e py35-ansible22-pylint
+```
 
+If you want to enter the virtualenv created by tox to do additional
+testing/debugging (py27-flake8 env in this case):
 ```
-nosetests
+source .tox/py27-ansible22-flake8/bin/activate
 ```
