+# Permission Scenario Testing
+
+Due to complexity that can arise in the various combinations of permissions, this document details scenarios and their expected results.
+
+Test cases are written ability abstract, since all abilities should act the same in theory. Functional test cases may test abilities separate due to implementation differences.
+
+## Cases
+
+### Entity Role Permissions
+
+These are tests related to entity-level role-specific permission overrides.
+
+#### entity_role_01 - Explicit allow
+
+- Page permissions have inherit disabled.
+- Role A has explicit page permission.
+- User has Role A.
+
+User should have page permission.
+
+#### entity_role_02 - Explicit deny
+
+- Page permissions have inherit disabled.
+- Role A has explicit page permission.
+- User has Role A.
+
+User should not have permission.
+
+#### entity_role_03 - Same level conflicting
+
+- Page permissions have inherit disabled.
+- Role A has explicit page permission.
+- Role B has explicit blocked page permission.
+- User has both Role A & B.
+
+User should have page permission. Explicit grant overrides explicit deny at same level.
