# 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.

Tests are categorised by the most specific element involved in the scenario, where the below list is most specific to least:

- Role entity permissions.
- Fallback entity permissions.
- Role permissions.

## General Permission Logical Rules

The below are some general rules we follow to standardise the behaviour of permissions in the platform:

- Most specific permission application (as above) take priority and can deny less specific permissions.
- Parent role entity permissions that may be inherited, are considered to essentially be applied on the item they are inherited to unless a lower level has its own permission rule for an already specific role.
- Where both grant and deny exist at the same specificity, we side towards grant.

## Cases
