+The testing system is based on a combination of tox and stestr. The canonical
+approach to running tests is to simply run the command ``tox``. This will
 create virtual environments, populate them with dependencies and run all of
 the tests that OpenStack CI systems run. Behind the scenes, tox is running
-`testr run --parallel`, but is set up such that you can supply any additional
-testr arguments that are needed to tox. For example, you can run:
-`tox -- --analyze-isolation` to cause tox to tell testr to add
---analyze-isolation to its argument list.

 It is also possible to run the tests inside of a virtual environment
 you have created, or it is possible that you have all of the dependencies
-installed locally already. In this case, you can interact with the testr
-command directly. Running `testr run` will run the entire test suite. `testr
-run --parallel` will run it in parallel (this is the default incantation tox

+as many threads as you have CPU cores (this is the default incantation tox

+``testr run --serial`` will run tests in serial process.

 Note that unit tests use a database if available. See
