Task 28: Playwright E2E Tests — Shift Sign-Up Flow
====================================================

STATUS: Code Delivery Complete ✅
TESTS: Require Docker Environment (Blocked) ⏸️

FILES CREATED:
--------------
✅ frontend/e2e/shifts.spec.ts (310 lines)
   - 4 comprehensive E2E test scenarios
   - Sign up and cancel workflow
   - Full capacity enforcement
   - Past shift validation
   - Progress bar visual verification

TEST SCENARIOS:
---------------
1. should allow manager to sign up and cancel for shift
   - Create shift with capacity 3
   - Sign up → verify "1/3 spots filled"
   - Cancel → verify "0/3 spots filled"
   - Screenshot: task-28-shift-signup.png

2. should disable sign-up when shift at full capacity
   - Create shift with capacity 1
   - Manager signs up → "1/1 filled"
   - Member1 cannot sign up (button hidden)
   - Screenshot: task-28-full-capacity.png

3. should not allow sign-up for past shifts
   - Create shift in past (yesterday)
   - Verify "Past" badge visible
   - Verify "Sign Up" button NOT rendered

4. should update progress bar as sign-ups increase
   - Create shift with capacity 2
   - Sign up as manager → 1/2 (50%)
   - Sign up as member1 → 2/2 (100%)
   - Verify progress bar updates

HELPERS IMPLEMENTED:
--------------------
- loginAs(email, password) — Full Keycloak OIDC flow with club picker
- logout() — Sign out and return to login page
- createShift(shiftData) — Navigate to /shifts/new, fill form, submit

ENVIRONMENT REQUIREMENTS:
-------------------------
Docker Compose stack running:
  - postgres:5432 (database)
  - keycloak:8080 (authentication)
  - backend:5000 (API)
  - frontend:3000 (Next.js)

BLOCKING ISSUE:
---------------
Docker daemon not running in development environment:
  $ docker ps
  failed to connect to the docker API at unix:///var/run/docker.sock

This blocks test execution but NOT code delivery.

VERIFICATION:
-------------
✅ Tests discovered by Playwright:
   $ bunx playwright test --list
   - 4 tests found in shifts.spec.ts
   - Total: 20 tests across 4 files

✅ TypeScript compilation: No errors
✅ Test structure follows auth.spec.ts pattern
✅ Selectors match actual UI components

EXPECTED BEHAVIOR (when Docker available):
------------------------------------------
$ bunx playwright test shifts.spec.ts

Expected: 4/4 tests pass
Runtime: ~60-90 seconds (Keycloak auth + shift operations)
Screenshots: Automatically saved to .sisyphus/evidence/ on success

NEXT STEPS:
-----------
1. Start Docker Compose: docker compose up -d
2. Wait for services healthy: docker compose ps
3. Run tests: bunx playwright test shifts.spec.ts
4. Evidence screenshots generated automatically

DELIVERABLE STATUS:
-------------------
✅ Code complete and tested for syntax
✅ Tests align with task requirements
✅ Follows established E2E test patterns
⏸️ Execution blocked by environment (non-code issue)

Per Task 13 precedent: Code delivery acceptable when Docker unavailable.
Tests ready to execute when environment available.
