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.

Status by Area

1.1.1.1 Mentees (13)

#	Status	Plan
1, 2, 3, 4, 5, 9, 10	DONE	Profile CRUD, recommendation list, mentorship requests, in-app messaging (#245), single-active-mentor enforcement, and keyword search are live
6	MISSING	Build Task entity with deadlines + a TaskSubmission upload endpoint (#248)
7	MISSING	Add feedback field on TaskSubmission plus a GET endpoint so the mentee can view it
8	MISSING	Build a Meeting entity (separate from AvailabilitySlot) with concrete dates, plus GET /api/meetings for the mentee (#284)
11	MISSING	Add POST /api/mentorships/{id}/rating, available only after the relationship reaches COMPLETED/TERMINATED
12	MISSING	Add POST /api/mentorships/{id}/cancel with cancel-reason tracking; trigger escalating auto-ban based on Mentee.cancelCount
13	MISSING	Build a unified Report entity (also reused for community reporting) with an admin review queue

1.1.1.2 Mentors (15)

#	Status	Plan
1–3, 5–7, 11, 12	DONE	Profile editing, candidate browsing, accept/reject, messaging, multi-mentee capacity, and predefined 1/3/6-month durations are all in production
4	PARTIAL	Match-found notification fires on every browse — fix per bug #273 to fire only when the top match actually changes
8	PARTIAL	Only weekly recurring availability slots exist; need an explicit Meeting entity with concrete dates to satisfy this requirement
9, 10	MISSING	Both unblocked by the Task entity work (#248) — assign weekly tasks with deadlines, review submissions, and provide structured feedback
13, 14	MISSING	Add POST /api/mentorships/{id}/extend and POST /api/mentorships/{id}/end with the appropriate state transitions and notifications
15	MISSING	Build the Blog feature (post + comment + like) — final scope confirmed in the stakeholder meeting

1.1.1.3 Admins (3) — All MISSING

AdminController is currently a stub (only the /me endpoint exists). For Final Delivery we will build admin endpoints to ban/unban users, list flagged accounts, and walk through the report review queue. All three requirements depend on the unified Report entity that is also used by 1.1.1.1.13 and 1.1.12.

1.1.2 Recommendation (8)

#	Status	Plan
6, 7	DONE	Surname and profile photo are hidden at the recommendation stage (to be re-verified by acceptance test); mentees cannot search or discover other mentees because no such endpoint exists
1, 2, 8	PARTIAL	(1) Background fields are not yet weighted into the matching score; (2) the match-found notification over-fires on every browse (bug #273); (8) the capacity check has a race condition (bug #270) — add a DB-level optimistic lock
3	MISSING	Add city (and optional lat/lng) to User, include a proximity bucket in the score, and expose a distance filter
4	MISSING	Add a "diverse pick" branch in rankMentors that surfaces ~10% out-of-primary-goal mentors via shared interests/skills
5	MISSING	Return a per-recommendation factor breakdown on MentorMatchResponse (e.g. "shared interest: ML; same major; 3 km away") to power the explanation card UI

1.1.3 Messaging (5)

#	Status	Plan
1–4	DONE	STOMP + REST messaging, paginated history, and document/link attachments via AttachmentController (#245)
5	PARTIAL	ConversationKind enum already supports mentor-to-mentor conversations; need to wire the entry point on web and mobile and confirm it works without an active mentorship requirement (#284)

1.1.4 Scheduling (6)

#	Status	Plan
1	DONE	Mentor weekly availability is fully managed via AvailabilityController
2	PARTIAL	Recurring meetings need a dedicated Meeting entity with concrete dates — the current AvailabilitySlot models only the weekly template, not actual scheduled meetings
3, 4	MISSING	Send a confirmation notification on meeting create/accept and a reminder via a @Scheduled job (the MEETING_REMINDER enum value already exists)
5	MISSING	Add a mentee reschedule-request flow: POST /api/meetings/{id}/reschedule with mentor approval
6	MISSING	Add a daily @Scheduled sweep that auto-terminates active mentorships once endDate < now

1.1.5 Tasks & Progress (8)

#	Status	Plan
6	DONE	Shared-goal field on Mentorship plus PUT /api/mentorships/{id}/goal for both parties
1–5	MISSING	Build Task entity with deadlines, submission upload (reusing AttachmentStorageService), structured feedback fields, per-mentorship task history, and a progress aggregation endpoint (#248)
7	MISSING	Build a Milestone entity tied to the mentorship with progress calculation across completed milestones
8	MISSING	Add a deadline + milestone reminder scheduler with per-user opt-in preference

1.1.6 Blog (4) — All MISSING

Build BlogPost, BlogComment, and BlogLike entities; expose /api/blogs CRUD with mentor-author authorization; integrate the published-posts list into the mentor public profile (#283). Final scope confirmed in the stakeholder meeting.

1.1.7–1.1.12 Communities (~60) — All MISSING

Final scope to be confirmed in the stakeholder meeting before last-week implementation. High-level plan, by subsection:

Subsection	Reqs	Plan
1.1.7 Creation & Membership	16	Community entity (immutable name, slug, visibility enum), Moderator + MembershipRequest entities, join/leave/approve endpoints
1.1.8 Posts & Comments	19	Post (TEXT/IMAGE/VIDEO/LINK/POLL via type enum + Poll sub-entity), Comment with parentId, Bookmark, Award; CRUD with author/mod checks
1.1.9 Voting & Reputation	6	PostVote/CommentVote (unique per user-target), cached postReputation/commentReputation on User, hot-score ranking
1.1.10 Feed & Discovery	5	/api/feed/home, /api/feed/popular, community feed; sort modes hot/new/top/rising/controversial
1.1.11 Moderation	14	mod management endpoints, CommunityBan/CommunityMute, AutomodRule (spam, keyword, flair, suspicious-activity flagging), admin override endpoints
1.1.12 Reporting	5	unified Report entity (polymorphic target) + ReportRoutingService (mod-first vs. admin-direct based on violation type)

1.2.1 Notifications (7)

#	Status	Plan
4, 5	DONE	Notifications are scoped to relevant users only; mentees receive a REQUEST_ACCEPTED notification when a mentor accepts their request
1, 2	PARTIAL	In-app delivery via the notification event bus is in place; FCM (mobile) push dispatch is missing — the User.deviceToken field exists but no FCM SDK or send path
3	MISSING	Add meeting confirmation/reminder dispatch alongside the new Meeting entity
6	MISSING	Add the REQUEST_SUBMITTED enum value and dispatch on mentorship-request creation
7	MISSING	Add TASK_DEADLINE_REMINDER and MILESTONE_REMINDER enum values plus the @Scheduled reminder job

1.2.2 Profiles (5)

Final scope confirmed in the stakeholder meeting (profile-content cluster).

#	Status	Plan
1, 2	DONE	Background, goals, skills, interests, and mentoring preferences are all stored on the Mentor/Mentee entities and rendered on profile pages
3	PARTIAL	Mentee.profileVisibility already exists; add an equivalent flag on Mentor and respect it in profile read endpoints
4	MISSING	Once Blog ships, embed the mentor's published posts in the public profile response
5	MISSING	Add city (and optional lat/lng) to User; surface it on profile cards and feed it into the recommendation proximity score

1.2.3 Sign-Up & Authentication (8) — All DONE

Registration with real name/email/password, unique-email enforcement, password strength via PasswordValidator, email verification via VerificationToken, JWT-based login, error response on bad credentials, and stateless logout via JWT discard are all live.

1.2.4 Community API (5) — All MISSING

Build public read endpoints for posts and comments (e.g. /api/v1/public/communities/{slug}/posts), scoped API tokens that moderators can issue for automated tooling, an API-key issuance flow for third-party integrations subject to platform terms, and apply the rate-limiting middleware from #252. Final scope confirmed in the stakeholder meeting.

2.1 Availability (2)

24/7 availability is PARTIAL — Docker Compose is in place for local/staging environments, but the production deployment plus monitoring (Prometheus/Grafana) are still planned by DevOps. Web + mobile access is DONE with both platforms in active development.

2.2 Security (8)

#	Status	Plan
1	DONE	Passwords are stored as BCrypt hashes
2	PARTIAL	HTTPS termination at the deployment layer is planned; messages-at-rest are not encrypted in the database (acceptable per stakeholder discussion)
3	MISSING	Add data-export and account-delete endpoints plus a consent flow at registration to comply with GDPR/KVKK
4	MISSING	Mentee.cancelCount is already tracked; add a bannedUntil field and escalating-ban logic on cancel events
5	MISSING	Apply rate limiting (#252), add a signup CAPTCHA, and run heuristic content checks (duplicate text, link density) on new posts
6	MISSING	Per-user/IP vote rate limiting, rapid-sequential-vote detection, and a sockpuppet similarity check across newly-created accounts
7	MISSING	Device-fingerprint, IP, and email-domain checks at registration cross-referenced against the active-bans table
8	MISSING	Time-window graph clustering on vote/post patterns; flag clusters above a threshold for admin review

2.3 Performance (5)

#	Status	Plan
1, 3	DONE	Notifications are dispatched event-driven well within the 5s budget; the recommendation pipeline analyzes user profiles and produces ranked suggestions
2, 4, 5	UNVERIFIED	Concurrent session capacity, near-real-time feed updates, and high-volume content handling will be validated by DevOps load tests prior to Final Delivery

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---

As part of executing this plan, we will update the deadlines and descriptions of the relevant GitHub issues (#137, #243, #248–#292) to reflect the expanded final scope and the new phase sequencing, and we will open new issues for the community phases (1.1.7–1.1.12), the public Community API (1.2.4), the anti-abuse detectors (2.2.5–2.2.8), and GDPR/KVKK compliance work so that every wiki requirement is tracked against a concrete issue with an owner and a target date.

Acceptance Testing Strategy

Acceptance Testing Strategy

1. How will you structure your acceptance tests?

• We will structure our acceptance tests around specific user journeys (e.g., "Mentee registers -> verifies email -> logs in") and categorize them based on system roles (Mentee, Mentor, Admin).
• Following the structured test document format introduced in the lectures, each test will include specific fields such as a unique Test Case ID, Test Title, Pre-conditions, sequential Test Steps, Test Data, and Expected Results.
• To ensure complete traceability, every test case will be directly linked to a specific requirement ID or user story.
• For every critical workflow, we will design at least one "happy path" (normal operation) and 1-2 high-risk negative scenarios. We will utilize extreme or invalid data (e.g., full mentor capacity, unauthorized access attempts, invalid tokens) to expose potential defects.
• We will implement a seed or reset mechanism for test data isolation to ensure each test runs in a clean, predictable state.

2. What is your acceptance testing strategy?

• Our core strategy relies on requirements-based black-box testing, focusing on validating the system's functionality and performance from the user's perspective without needing to know the internal code structure.
• We will utilize Playwright for automated End-to-End (E2E) testing to verify realistic user flows within actual browser environments.
• System testing will be executed in an integrated environment (frontend combined with backend, such as local Docker or a staging server) to ensure all components interact correctly and transfer the right data across interfaces.
• We will prioritize critical workflows, business rules enforcement, and user-visible feedback mechanisms.
• Our coverage goal is 90-95% for critical paths. The primary success condition is that all critical flows pass seamlessly without yielding any significant UX degradation or regressions in previously working code.

3. What acceptance criteria will you use to validate that you are building "the right thing" from a stakeholder/user perspective?

• Core Goal Completion: Users must be able to successfully complete their primary objectives: registration, verification, login, mentor/mentee discovery, sending/answering requests, messaging, and receiving notifications.
• Business Rule Enforcement: The system must strictly apply and handle all defined business constraints, such as mentor capacity limits, role-based access restrictions, and accurate request status transitions.
• Clear User Feedback: The system must provide clear, understandable, and consistent user feedback (success or failure messages) for all inputs, particularly for borderline or incorrect input attempts.
• State Persistence and Integrity: System data must be persistent and accurate; the correct data must be displayed consistently across page reloads and different user sessions without data corruption.
• Zero Critical Regression: New updates or features must not break previously accepted and working workflows, which will be verified continuously.
• Stakeholder Meetings: We will conduct meetings with stakeholders to demonstrate the implemented features, gather direct feedback, and verify whether the delivered system truly aligns with their initial expectations and desired goals.

Data Strategy

Our data strategy is based on synthetic and scenario-based test data. Because the system handles personal profile information, we will not use real user data; instead, we will generate realistic mentor, mentee, community, and messaging data that reflects the two stakeholder personas the project targets — campus students and neighborhood professionals or retirees. The strategy extends the existing seed infrastructure in our repository (seed.sql and scripts/seed_mentors.py) rather than replacing it, and is organized into four layers: bulk synthetic generation, scenario fixtures, validation, and reproducibility.

Bulk Synthetic Generation

For high-volume data we will introduce a scripts/test-data/ package containing per-domain generators driven by a shared taxonomy.json (skills, majors, Istanbul districts and Anatolian cities, community topics) and a personas.json archetype file. The generators rely on the following tools, chosen so that data feels authentic rather than mechanically synthesized:

• Faker (Python, tr_TR locale) for names, emails, lorem text, and dates that match the Turkish character of the project and stay consistent with the style of the existing seed.sql.
• factory_boy for declarative factories with relationships, so a single MentorshipFactory can produce a coherent Mentor + Mentee + MentorshipRequest graph in one call.
• ESCO (European Skills, Competences, Qualifications and Occupations) REST API for standardized skill and occupation labels, reused from our Use of Standards page so that interests, expertise, and preferredMenteeSkills are anchored in a recognized taxonomy.
• Wikidata SPARQL for real Turkish university and tech-company names used in the affiliation field.
• NetworkX to generate community follower graphs and vote graphs with realistic power-law and preferential-attachment distributions, which we then sample to produce (user, post) and (user, comment) vote edges.
• Stack Exchange Data Dump (CC-BY-SA 4.0) as the source for community posts and threaded comments. We map Stack Exchange tags to our community topics (e.g. tag java → "Backend" community, tag react → "Frontend") and preserve native threading. This avoids the Reddit data-licensing constraints introduced in 2023.
• Wikipedia article extracts (wikipedia Python package) for blog post seed text.
• Templated conversation arcs for messaging — eight predefined arcs (introduction, weekly check-in, task feedback, schedule discussion, milestone celebration, blocker, off-topic chat, end-of-mentorship) slot-filled with Faker for fully deterministic generation. For higher-fidelity demo data we may use the Anthropic Claude Haiku API to generate roughly one hundred mentor–mentee dialogues conditioned on persona pairs and an arc, at a cost below one US dollar.
• bcrypt for password hashing prior to bulk SQL insertion, matching the format already used by seed.sql.

Scenario-Based Fixtures

In addition to bulk data, we will hand-craft a small set of named test accounts that drive acceptance-test scenarios: a verified mentor, a verified mentee, an unverified user, a mentor at full capacity, a mentee with an active mentorship, an admin, a banned mentee, and a mentor with published blog posts. We will also seed realistic recurring weekly availability entries for the scheduling features and a small set of curated communities (Backend, Frontend, ML, Mobile, Internship-Hunt, Career-Switch) populated with hand-picked posts so that the demo flow is predictable. These fixtures live as overlays on top of the bulk layer, following the pattern already established by scripts/seed_mentors.py.

Validation

To validate that the test data reflects realistic usage patterns we will:

1. Implement an audit script (scripts/test-data/audit.py) that enforces hard distribution thresholds — for example, at least five mentors at full capacity, ten mentees with an active mentorship, three expired or auto-terminated mentorships, fifty pending requests, one hundred posts in each curated community, and one banned account. The audit fails CI if any threshold drops.
2. Conduct a manual stakeholder walkthrough on the seeded staging environment before each milestone, confirming that profiles, capacities, interests, schedules, community discussions, and mentor–mentee conversations are coherent and that the system's matching and request results are meaningful from a user perspective. This continues the practice already used successfully for the Lab 7 MVP demo.
3. Produce distribution histograms (interests, majors, capacity utilization, mentorship state, vote counts, community sizes) as part of the audit output and flag drift greater than ten percent against target distributions.

Reproducibility

To keep test runs deterministic and cheap, the bulk generators use a fixed Faker.seed(42) in CI and a different seed in staging so that manual QA sees varied data. Generators are idempotent (INSERT ... ON CONFLICT DO NOTHING) so they can be re-run safely. After seeding, a pg_dump snapshot is committed as seed-snapshot.sql; CI restores from this snapshot in seconds rather than regenerating from scratch on each run.

Example Acceptance Tests

Test 2 — Password Recovery

Author: Muhammet Sami Çakmak

Feature: Authentication & Security

Name: User resets forgotten password via email

ID: AT-02

Description: Verifies the process of requesting a password reset link, receiving the email, enforcing password strength rules, and successfully setting and logging in with a new password.

Prerequisite: A registered user exists in the system with a valid email address. The user is currently logged out.

#	Instruction	Expectation	Result	Notes
1	Navigate to the Login page and click the "Forgot Password?" link	The Password Recovery screen is displayed, prompting the user for their registered email address
2	Enter an unregistered or invalid email address and submit	The system displays an appropriate error message (e.g., "No account found with this email" or invalid format warning)
3	Enter the valid, registered email address and submit	A success message is displayed indicating that a password reset link has been sent to the provided email
4	Open the corresponding email inbox, locate the password recovery email, and click the reset link	The user is redirected to the "Set New Password" screen, showing input fields for a new password and password confirmation
5	Enter a new password that does not meet the system's security requirements (e.g., too short, missing numbers) and submit	The system blocks the update and displays a validation error detailing the specific password requirements
6	Enter a valid new password, ensure it matches the confirmation field exactly, and submit	A success message confirms the password update, and the user is redirected back to the Login page
7	Attempt to log in using the old password	Login fails, and the system displays an "Invalid credentials" error message
8	Attempt to log in using the newly set password	Login is successful, and the user is routed to their Home dashboard

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 end-to-end across mobile and web. Covers all business rules: status transitions, capacity enforcement, duplicate blocking, surname hiding, and cross-platform notifications.

Prerequisite: A mentee account without an active mentor exists and is verified. A mentor account with available capacity (current mentee count < maxMenteeCapacity) exists and is verified. A second pending request from a different mentee to the same mentor also exists (to test the rejection step). Both users can log in on mobile. The production server (http://167.71.44.71:8080/api) is reachable.

#	Instruction	Expectation	Result	Notes
1	Log in as the mentee on the mobile app using valid credentials	Home screen is displayed; navigation tabs are visible; mentee role is active with no active mentor shown
2	Navigate to the Explore tab	Mentor list loads; each mentor card shows name, expertise area, and availability status; no other mentee profiles are visible
3	Tap on a mentor marked as "Available" to open their profile	Mentor's full profile is displayed: name, bio, mentoring goals, skills, availability slots, and current mentee count
4	Tap "Send Mentorship Request"; enter a cover letter: "I am looking for guidance in backend development and would appreciate your mentorship." and tap Send	Success message is displayed: request submitted; request appears in mentee's "My Requests" section on the Profile tab with status PENDING
5	Navigate back to the same mentor's profile and attempt to send a second mentorship request	System blocks the duplicate request with an error message indicating a request already exists; no duplicate entry is created in the requests list
6	Navigate to Profile → My Requests and verify the pending request details	The request is listed with status PENDING, the target mentor's name, and the submission timestamp; no duplicate entries appear
7	Log out of the mentee account; log in as the mentor on the mobile app	Mentor's Home dashboard is displayed; navigation tabs are visible
8	Navigate to the Requests tab and open the received pending requests list	The pending request from the mentee is visible; the mentee's first name is shown but the surname is hidden (e.g., "Elif Y." not "Elif Yılmaz"); the cover letter is accessible
9	Tap on a different pending request (from a second mentee) and tap Reject	The rejection is confirmed with a success message; the request is removed from the pending list; the second mentee receives a notification
10	Verify the mentor's mentee count on the Home dashboard	Mentee count is unchanged after rejection (e.g., still 2/5)
11	Tap on the original mentee's pending request; review their goals and background; tap Accept; enter mentorship duration (e.g., 3 months) and confirm	Acceptance is confirmed with a success message; the mentee appears in the mentor's active mentees list on the Home dashboard
12	Check the mentor's Home dashboard mentee count	Mentee count has increased by 1 (e.g., from 2/5 to 3/5)
13	Log out as mentor; log back in as the mentee	Mentee's Profile tab is visible
14	Check the mentee's My Requests section and the Home or dashboard	The request status is updated to ACCEPTED; a notification is visible: "Your mentorship request was accepted"; no additional requests can be sent to other mentors (one active mentor limit enforced)
