+The reason that every roles test gets its own directory is that while they
+use the same three roles, the way the tests work makes sure that when the
+second one runs, the roles and their local plugins from the first test are
+still known to Ansible. For that reason, their names reflect the directory
+they are in to make sure that tests don't use modules/plugins found by
+other tests.
