+You can unit test in docker or outside of docker.
+The preferred method (by far) is to use Docker, because it encapsulates rmr, as well as ensuring that ports that rmr opens do not conflict with the host machine
+
+::
+
+ docker build -t rmrunittestt:latest -f Dockerfile-Unit-Test .
+
+A coverage report will be shown in stdout.
+
+It is possible to run tox locally provided that rmr is intalled, and you are prepared to have the test open ports (4562) as ``rmr_init`` must succeed for the tests to proceed.
