The Test:

In the DEV/Staging environment

• create a new user - PASSED (BZ user 1821)
• validate the user email address - PASSED
• create a new unit - PASSED (BZ unit 1256)
• create a new case in that unit - PASSED (case 74013)
  • during case creation, assign that unit to a new user I just invited (BZ user 1823)

Expected result:

• User 1823 receives a notification PASSED
• Notification received is for "New Case created" and using the updated format

Actual result:

• Notification is in a format which is different from what was expected

The Test:

In the DEV/Staging

• As BZ user 1821
• Create a new case in the BZ unit 1256
• Assign the case to my role (BZ user 1821)
• Case is assigned to the case creator (the default user in the role "Tenant")
• Make sure the case is created - PASSED - case 74014
• Invite BZ user 1823 to the case.

Expected result:

• User 1823 can see the case - PASSED
• An email notification is received by user 1823 - FAILED (email was not received after 15mm)

I should have merged before doing the tests... (duh!)

All is working as intended in the DEV/Staging
