Requirements Review

Methodology

We revisited every wiki requirement and tagged each as DONE, PARTIAL, or MISSING against the current code. All wiki requirements are committed to Final Delivery — none are deferred.

Scoping meeting for Blog, Community, and Profile-content requirements. Before implementing the Blog (1.1.6), Community (1.1.7–1.1.12 and 1.2.4), and Profile-content (1.2.2) clusters, we will hold a dedicated meeting with the instructor and a project stakeholder to confirm priorities, refine user-facing surfaces, and lock acceptance criteria. The meetings are scheduled this fridayand the second one in the final week of the project, after the smaller well-bounded features (mentorship lifecycle, meetings, tasks, advanced recommendation, notifications, admin) have shipped, so the community-style features are implemented against confirmed scope.

Pre-existing Bug Fixes (Lab 8 Backlog)

Five backend bugs identified in Lab 8 must be closed before final delivery:

• #270 Mentor capacity race in MentorshipService.acceptRequest — add DB-level optimistic lock
• #271 NPE risk when JWT lacks userId/role claims — null-safe JwtAuthenticationFilter
• #272 Inconsistent timezone handling — standardize on Clock + UTC OffsetDateTime
• #273 Match-found notification fires on every browse — fire only on new top-match change
• #274 Missing per-resource authorization on GET /api/availability/{mentorId}

Plan to Address Unimplemented Requirements

The Final Milestone plan (wiki) is being expanded to cover every wiki requirement — none are deferred. Priority order for the remaining sprints:

1. Core mentorship lifecycle — end/extend/cancel/auto-terminate/auto-ban/rate
2. Meetings — Meeting entity + reminders + reschedule flow
3. Tasks & milestones — Task/Milestone entities, submissions, feedback, progress aggregation
4. Recommendation overhaul — location, diversity, explanation
5. Blog — full CRUD + mentor profile integration (#283)
6. Notifications — FCM dispatch, new types, reminder schedulers
7. Admin & moderation — admin endpoints (ban/list/reports), unified Report entity (shared with community reporting)
8. Communities — Phase A Community + membership + visibility + moderator role (1.1.7)
9. Communities — Phase B Posts (text/image/video/link/poll), edit/delete, share/save, mod approval, pin (1.1.8 posts)
10. Communities — Phase C Comments, replies, comment voting, awards (1.1.8 comments)
11. Communities — Phase D Voting + reputation scoring (1.1.9)
12. Communities — Phase E Feeds (home / popular / community-specific) + sort modes (1.1.10)
13. Communities — Phase F Moderation + automoderation rules + admin oversight (1.1.11)
14. Communities — Phase G Reporting flow (extends shared Report) (1.1.12)
15. Public Community API + integrations with rate-limiting middleware (1.2.4)
16. Anti-abuse hardening — spam-bot, vote-manipulation, ban-evasion, coordinated-abuse detectors (2.2.5–2.2.8)
17. GDPR/KVKK compliance — data-export + delete endpoints + consent UI
18. Lab 8 bug closures — five fixes (#270–#274)
19. DevOps hardening — production deploy, monitoring (Prometheus + Grafana), load testing for performance requirements 2.3.2 and 2.3.5

Example Acceptance Tests

Test 5 — Mentorship Request Lifecycle

Author: Burak Ögüt (2021400168)

Feature: Mentorship Requests

Name: Mentor and mentee complete request lifecycle

ID: AT-05

Description: Verifies request creation, sent/received listing, duplicate prevention, rejection, and acceptance of mentorship requests.

Prerequisite: A mentee without an active mentor exists, a mentor with available capacity exists, and both users have verified accounts.

#	Instruction	Expectation	Result	Notes
1	Log in as the mentee on the mobile app	Home screen is displayed; mentee role is active
2	Navigate to the Explore tab and select an available mentor; tap "Send Mentorship Request"; enter a cover letter and submit	Success message is displayed confirming the request was submitted; request appears in the mentee's "My Requests" list with status PENDING		Req 1.1.1.1.4, 1.2.1.6
3	Attempt to send a second mentorship request to the same mentor	System blocks the duplicate request with an appropriate error message; no second request is created		Business rule: one active request per mentor–mentee pair
4	Log out and log in as the mentor	Mentor's Home dashboard is displayed
5	Open the received requests list (Requests tab)	The pending request from the mentee appears in the list with mentee's first name visible but surname hidden		Req 1.1.2.6, 1.1.1.2.4
6	Reject one pending request (if another pending request is available) by tapping Reject	The rejected request is removed from the pending list; the corresponding mentee receives a rejection notification; mentor mentee count is unchanged		Req 1.1.1.2.6
7	Tap on the valid pending request from the mentee; review the profile; tap Accept and provide mentorship duration information	Acceptance is confirmed with a success message; the mentee is added to the mentor's active mentees list; mentor mentee count increases by 1		Req 1.1.1.2.6, 1.1.1.2.12, 1.2.1.5
8	Reopen the requests list and navigate to the mentee's active mentorships on the Home dashboard	The accepted request no longer appears in pending list; the mentee is listed as an active mentee; the mentee's app shows the mentorship as active		Req 1.1.1.1.9: mentee limited to one active mentor
