Reviewer Role allowed in permission scheme to Approve / Reject reviews cannot do that

Crucible Project Configuration:

1. Three users involved: user1, user2 and user3
2. Edited the default Permission Scheme in order to make the Reviewer role be able to approve and reject a review:

   Permissions	Users / Groups / Review Roles
   Approve	Review Roles: Moderator, Reviewer
   Reject	Review Roles: Moderator, Reviewer

3. Edited the CR Crucible project and:
   • Ensured that it is using the default Permission Scheme.
   • Enabled the Moderator role for that project, selecting user1 as default moderator
   • Selected user2 and user3 as Default reviewers

First test, with a Default Moderator selected

Review CR-1 created with user1:

1. The Add content screen shows buttons Add More Content, Edit Details, Abandon Review, Start Review and Done
2. Clicked Done and the default reviewers user2 and user3 were added to the review. user1 shows up as Author & Moderator
3. Clicked Start Review and it was sent to reviewers user2 and user3
4. Logged out, then logged in as user2 / user3 and accessed CR-1, whose status is OPEN.
   • Expected: see Approve and Reject buttons, but none got displayed. Just Complete button was displayed.

Review CR-2 created with user3:

1. The Add content screen shows buttons Add More Content, Edit Details, Abandon Review, Send to Moderator and Done
2. Clicked Done, and user3 shows up only as Author, user1 shows up as Moderator, and user2 shows up as Reviewer.
   • Expected: as reviewers are allowed to Approve and Reject reviews, user3 should not need to click Send to Moderator for approval / rejection.

Second test, keeping the Moderator role enabled but removing user1 as Default moderator on that Crucible project

Review CR-3 created with user1:

1. The Add content screen shows buttons Add More Content, Edit Details, Abandon Review, Start Review and Done
2. Clicked Done and the default reviewers user2 and user3 were added to the review. user1 shows up as Author & Moderator
3. Clicked Start Review and it was sent to reviewers user2 and user3
4. Logged out, then logged in as user2 / user3 and accessed CR-3, whose status is OPEN.
   • Expected: see Approve and Reject buttons, but none got displayed. Just Complete button was displayed.

Review CR-4 created with user2:

1. The Add content screen shows buttons Add More Content, Edit Details, Abandon Review, Start Review and Done
2. Clicked Done, and user2 shows up as Author and Moderator, user3 shows up as Reviewer, and user1 was not listed
   • Expected: see Approve and Reject buttons, but none got displayed. Just Edit Details and Start Review buttons were displayed.
3. Clicked Start Review
4. Logged out, then logged in with user3
   • Expected: see Approve and Reject buttons, but none got displayed. Just Complete button was displayed.

Result:

It doesn't matter if there is a Moderator selected or not. Reviewers cannot ever Approve / Reject reviews.
