+corresponding API endpoint, access is only granted for correct roles.
+
+Currently, Patrole supports policies contained in code and in policy.json files.
+If both exist, the policy actions in the policy.json are prioritized.
+
+.. _test-flows:
+
+Test Flows
+----------
 
 There are several possible test flows.
 
-If the rbac_test_role is allowed to access the endpoint
- - The test passes if no 403 forbidden or RbacActionFailed exception is raised.
+If the ``rbac_test_role`` is allowed to access the endpoint:
 
-If the rbac_test_role is not allowed to access the endpoint
- - If the endpoint returns a 403 forbidden exception the test will pass
- - If the endpoint returns something other than a 403 forbidden to indicate
-   that the role is not allowed, the test will raise an RbacActionFailed exception.
+* The test passes if no 403 ``Forbidden`` or ``RbacActionFailed`` exception is raised.
+
+If the ``rbac_test_role`` is not allowed to access the endpoint:
+
+* If the endpoint returns a 403 `Forbidden` exception the test will pass.
+* If the endpoint returns successfully, then the test will fail with an
+  ``RbacOverPermission`` exception.
+* If the endpoint returns something other than a 403 ``Forbidden`` to indicate
+  that the role is not allowed, the test will raise an ``RbacActionFailed`` exception.
+
+.. note::
+
+    Certain services like Neutron *intentionally* raise a 404 instead of a 403
+    for security concerns. Patrole accomodates this behavior by anticipating
+    a 404 instead of a 403, if specified through a special argument. For more
+    information about Neutron's policy enforcement, see:
+    `<https://docs.openstack.org/developer/neutron/devref/policy.html#request-authorization>`__.
+
+How It Works
+============
+Patrole leverages oslo_policy (OpenStack's policy enforcement engine) to
+determine whether a given role is allowed to perform a policy action given a
+specific rule and OpenStack service. This is done before test execution inside
+the ``rbac_rule_validation.action`` decorator. Then, inside the test, the API
+that does policy enforcement for the same rule is called. The outcome is
+compared against the result from oslo_policy and a pass or fail is determined
+as outlined above: :ref:`test-flows`.
+
+.. note::
+
+    Currently, Patrole does not support checking multiple rules against a single
+    API call. Even though some APIs enforce multiple rules (some indirectly),
+    it is increasingly difficult to maintain the tests if multiple policy
+    actions are expected to be called.
+
+Test Execution Workflow
+-----------------------
+
+The workflow is as follows:
+
+#. Each test uses the ``rbac_rule_validation.action`` decorator, like below: ::
+
+    @rbac_rule_validation.action(
+        service="nova",
+        rule="os_compute_api:servers:stop")
+    @decorators.idempotent_id('ab4a17d2-166f-4a6d-9944-f17baa576cf2')
+    def test_stop_server(self):
+        # Set the primary credential's role to "rbac_test_role".
+        self.rbac_utils.switch_role(self, toggle_rbac_role=True)
+        # Call the API that enforces the policy action specified by "rule".
+        self._test_stop_server()
+
+   The ``service`` attribute accepts an OpenStack service and the ``rule`` attribute
+   accepts a valid OpenStack policy action, like "os_compute_api:servers:stop".
+
+#. The ``rbac_rule_validation.action`` decorator passes these attributes,
+   along with user_id and project_id information derived from the primary
+   Tempest credential (``self.os.credentials.user_id`` and ``self.os.credentials.project_id``),
+   to the ``rbac_policy_parser``.
+
+#. The logic in ``rbac_policy_parser`` then passes all this information along
+   and the role in ``CONF.rbac.rbac_test_role`` to oslo_policy to determine whether
+   the ``rbac_test_role`` is authorized to perform the policy action for the given
+   service.
+
+#. After all of the logic above has executed inside the rbac decorator, the
+   test is executed. The test then sets up test-level resources, if necessary,
+   with **admin** credentials implicitly. This is accomplished through
+   ``rbac_utils.switch_role(toggle_rbac_role=False)``: ::
+
+    @classmethod
+    def setup_clients(cls):
+        super(BaseV2ComputeRbacTest, cls).setup_clients()
+        cls.auth_provider = cls.os.auth_provider
+        cls.rbac_utils = rbac_utils()
+        cls.rbac_utils.switch_role(cls, toggle_rbac_role=False)
+
+   This code has *already* executed when the test class is instantiated, because
+   it is located in the base rbac test class. Whenever ``cls.rbac_utils.switch_role``
+   is called, one of two behaviors are possible:
+
+    #. The primary credential's role is changed to admin if ``toggle_rbac_role=False``
+    #. The primary credential's role is changed to ``rbac_test_role`` if
+       ``toggle_rbac_role=True``
+
+   Thus, at the *beginning* of every test and during ``resource_setup`` and
+   ``resource_cleanup``, the primary credential has the admin role.
+
+#. After preliminary test-level setup is performed, like creating a server, a
+   second call to ``self.rbac_utils.switch_role`` is done: ::
+
+    self.rbac_utils.switch_role(cls, toggle_rbac_role=True)
+
+   Now the primary credential has the role specified by ``rbac_test_role``.
+
+#. The API endpoint in which  policy enforcement of "os_compute_api:servers:stop"
+   is performed can now be called.
+
+   .. note:
+
+        To determine whether a policy action is enforced, refer to the relevant
+        controller code to make sure that the policy action is indeed enforced.
+
+#. Now that a call is made to "stop_server" with the primary credentials having
+   the role specified by ``rbac_test_role``, either the nova contoller will allow
+   or disallow the action to be performed. Since the "stop_server" policy action in
+   nova is defined as "base.RULE_ADMIN_OR_OWNER", the API will most likely
+   return a successful status code. For more information about this policy action,
+   see `<https://github.com/openstack/nova/blob/master/nova/policies/servers.py>`__.
+
+#. As mentioned above, the result from the API call and the result from oslo_policy
+   are compared for consistency.
+
+#. Finally, after the test has executed, but before ``tearDown`` or ``resource_cleanup``
+   is called, ``self.rbac_utils.switch_role(cls, toggle_rbac_role=False)`` is
+   called, so that the primary credential yet again has admin permissions for
+   test clean up. This call is always performed in the "finally" block inside
+   the ``rbac_rule_validation`` decorator.
+
+.. warning::
+
+    Failure to call ``self.rbac_utils.switch_role(cls, toggle_rbac_role=True)``
+    inside a test with the ``rbac_rule_validation`` decorator applied results
+    in a ``RbacResourceSetupFailed`` being raised, causing the test to fail.

+Running Patrole Tests in Tempest
+================================
 
-    If patrole is installed correctly tests are run like any others.
+If Patrole is installed correctly, then the API tests can be executed
+from inside the tempest root directory as follows: ::
 
-    To change the role that the patrole tests are being run as edit rbac_role
-    in the rbac section of tempest.conf.
+    tox -eall-plugin -- patrole_tempest_plugin.tests.api
+
+To execute patrole tests for a specific module, run: ::
+
+    tox -eall-plugin -- patrole_tempest_plugin.tests.api.compute
+
+To change the role that the patrole tests are being run as, edit
+``rbac_test_role`` in the ``rbac`` section of tempest.conf: ::
+
+    [rbac]
+    rbac_test_role = Member
+    ...
+
+.. note::
+
+    The ``rbac_test_role`` is service-specific. Member, for example,
+    is an arbitrary role, but by convention is used to designate the default
+    non-admin role in the system. Most patrole tests should be run with
+    **admin** and **Member** roles. However, some services, like Heat, take
+    advantage of a role called **heat_stack_user**, as it appears frequently
+    in Heat's policy.json.
+
+For more information about the Member role,
+please see: `<https://ask.openstack.org/en/question/4759/member-vs-_member_/>`__.
