SU Tool - Test Plan

SAK-131: Add Role based SU security

This request to add Role-based SU security encompasses two parts:

a role-based specification of who may use superuser (SU) access and what the limitations of SU access are based on the user's original role, and
allows the portal to recognize that the user is in an SU role and provide a UI mechanism (link or button) for the user to leave SU and return to their own role without having to log out and log in again.

The story details of these separate tasks are listed as:

SAK-354: Add Role based SU security
SU tool uses Security(Service).isSuperUser() to determine who can SU. This should be modified to use agent - function - target ....

IT Express - can su - students
IT Express - can su - faculty
IT Express - cannot su - admin

SAK-367 - CharonPortal Tracking of assumed Id's with 'Return to...'
part two of two
2) CharonPortal patch: - assumed identities tracked with 'Return to <Eid>' link next to Logout link
create special url ('/realuser') that the portal will use to reload any existing previous usage session

Test for SAK-354

SAK-354: add realm based security to SuTool

This test plan covers the sub-story SAK-354: add realm based security to SuTool ONLY

Description:
This modification to the SU Tool is intended to allow users who do not have sakai SuperUser access to SU other users, e.g., allow IT Express personnel to SU without having admin access. On Start up, the tool looks for or creates a security realm (reference: realms tool).... by default the realms name is '!su.can_su_realm' but it can be modified by editing the tool registration file.

Administrators should add roles to this realm which have the appropriate security function (or permission). This function name is 'su.can_su' by default (but can be changed by an administrator by editing the tool registration file).

The template permission matrix with an example of source, function, target, and results:

source	function	target	result
user A	can SU	user B	true/false

Definitions: Types of users

SuperUser = any user who the ability to edit Realms within Administration Workspace (i.e., a SmartSite admin user)
Priv User = users who are added to a role in the 'SU Realm' which has the 'Can SU' security function (i.e., an IT Express user assigned to this role)
Standard User = any user who is not a SuperUser, and who

has not been added to a role in the 'SU Realm' which has the 'Can SU' security function, or
has been added to a role in the 'SU Realm' which does not have the 'Can SU' security function

What is expected:

Test #	source	function	target	result
Test 3	SuperUser	can SU	SuperUser	false
Test 7a	SuperUser	can SU	Priv User	true
Test 3	SuperUser	can SU	Standard User	true
Test 5	Standard User	can SU	SuperUser	false
Test 7b	Standard User	can SU	Priv User	false
Test 4	Standard User	can SU	Standard User	false
Test 6a	Priv User	can SU	SuperUser	false
Test 6b	Priv User	can SU	Standard User	true
Test 6c	Priv User	can SU	Priv User	true

Preparation

Requires initial SU Tool Setup in Realms if this is a new system.
SuperUser access is required for Administration Workspace changes
A test site with the SU Tool installed (see #SU Tool Setup to set up a course)
At least two non-SuperUser accounts in the test site (e.g., sakaiinst user or a non-SuperUser test partner)
Knowledge of 1-2 other SuperUser logins

Test Series

Assumption

Default realm name and default security function name in tool reg file

Login as admin, access the Realms tool, and delete the the realm entitled '!su.can_su_realm'.
Select the test site that contains the SU Tool.
Type the name of any non-admin or admin user and select 'Become User' button (the latter case will fail the su, but should achieve the desired results for this test.)
If necessary, log out and re-login as an admin user.
Return to Realms tool and search for the above realm name.

Log out and re-login as a non-admin user in the test site with the SU Tool.

If necessary, log out and re-login as an admin user.
Return to Realms tool and search for the above realm name.

Expected result: '!su.can_su_realm' will be created if missing the first time the tool is opened by a Standard User.

Test 3 - Validate SuperUser can SU other users except another SuperUser
