Ready for Review

Epic Reference

Epic 3: Booking & Consultation System

Story

As a client, I want to submit a consultation booking request, so that I can schedule a meeting with the lawyer.

Acceptance Criteria

Booking Form (AC1-5)

  1. Client must be logged in
  2. Select date from availability calendar
  3. Select available time slot
  4. Problem summary field (required, textarea, min 20 characters)
  5. Confirmation before submission

Validation & Constraints (AC6-9)

  1. Validate: no more than 1 booking per day for this client
  2. Validate: selected slot is still available
  3. Validate: problem summary is not empty
  4. Show clear error messages for violations

Submission Flow (AC10-14)

  1. Booking enters "pending" status
  2. Client sees "Pending Review" confirmation
  3. Admin receives email notification
  4. Client receives submission confirmation email
  5. Redirect to consultations list after submission

UI/UX (AC15-18)

  1. Clear step-by-step flow
  2. Loading state during submission
  3. Success message with next steps
  4. Bilingual labels and messages

Quality Requirements (AC19-22)

  1. Prevent double-booking (race condition)
  2. Audit log entry for booking creation
  3. Tests for submission flow
  4. Tests for validation rules

Calendar Integration Note

The availability-calendar component (from Story 3.3) uses the pattern $parent.selectSlot() to communicate slot selection back to the parent component. The parent booking component needs to have the selectSlot(string $date, string $time) method to receive this.

1-Per-Day Validation Rule

Files to Create

File Purpose
resources/views/livewire/client/consultations/book.blade.php Main Volt component for booking submission
app/Rules/OneBookingPerDay.php Custom validation rule for 1-per-day limit
app/Mail/BookingSubmittedMail.php Email to client on submission
app/Mail/NewBookingRequestMail.php Email to admin for new booking
tests/Feature/Client/BookingSubmissionTest.php Feature tests for booking flow

Mail Classes

Create mail classes using artisan:

php artisan make:mail BookingSubmittedMail
php artisan make:mail NewBookingRequestMail

Both mail classes should:

  • Accept Consultation $consultation in constructor
  • Use bilingual subjects based on recipient's preferred_language
  • Create corresponding email views in resources/views/emails/

Translation Keys Required

Add to lang/en/booking.php:

'request_consultation' => 'Request Consultation',
'select_date_time' => 'Select a date and time for your consultation',
'selected_time' => 'Selected Time',
'problem_summary' => 'Problem Summary',
'problem_summary_placeholder' => 'Please describe your legal issue or question in detail...',
'problem_summary_help' => 'Minimum 20 characters. This helps the lawyer prepare for your consultation.',
'continue' => 'Continue',
'confirm_booking' => 'Confirm Your Booking',
'confirm_message' => 'Please review your booking details before submitting.',
'date' => 'Date',
'time' => 'Time',
'duration' => 'Duration',
'submit_request' => 'Submit Request',
'submitted_successfully' => 'Your booking request has been submitted. You will receive an email confirmation shortly.',
'already_booked_this_day' => 'You already have a booking on this day.',
'slot_no_longer_available' => 'This time slot is no longer available. Please select another.',
'slot_taken' => 'This slot was just booked. Please select another time.',

Add corresponding Arabic translations to lang/ar/booking.php.

Risk Assessment

Risk Impact Mitigation
Double-booking race condition High DB transaction with lockForUpdate()

Timezone confusion Low Use whereDate() for date comparison

Estimation

Complexity: Medium-High Estimated Effort: 4-5 hours

Change Log

Date Version Description Author
2025-12-26 1.0 Initial draft -

QA Results

Review Date: 2025-12-26

Reviewed By: Quinn (Test Architect)

Risk Assessment

Review Depth: Standard - No high-risk triggers detected (no auth/payment files modified beyond expected booking flow, reasonable test coverage, appropriate line count, first review).

Code Quality Assessment

Overall: Excellent - The implementation is clean, well-structured, and follows Laravel/Livewire best practices.

Strengths:

  • Clean Volt component architecture with proper separation of concerns
  • Excellent race condition prevention using DB::transaction() with lockForUpdate()
  • Double validation strategy (pre-confirmation + in-transaction) provides defense in depth
  • Proper use of Flux UI components throughout
  • Bilingual support complete with proper RTL handling in email templates
  • Good error handling with user-friendly messages

Code Patterns:

  • book.blade.php:76-134 - Transaction with pessimistic locking correctly prevents race conditions
  • book.blade.php:48-52,90-95 - 1-per-day validation checked both pre and in-transaction
  • Mail classes properly use Queueable trait and respect user's preferred_language

Test Architecture Assessment

Test Count: 18 tests, 50 assertions Test Level: Feature tests (appropriate for this user-facing workflow) Test Quality: High - tests cover happy path, validation, business rules, race conditions, and side effects

Coverage Analysis:

  • ✓ Happy path submission flow
  • ✓ Authentication guard
  • ✓ All validation rules (required, min, max)
  • ✓ Business rules (1-per-day, slot availability)
  • ✓ Race condition scenarios (slot taken, user double-book)
  • ✓ UI flow states (confirmation, back navigation, clear selection)
  • ✓ Side effects (emails queued, audit log created)

Test Design Quality:

  • Proper use of Mail::fake() for email assertions
  • Good isolation with beforeEach for working hours setup
  • Race condition tests simulate real concurrent booking scenarios
  • Tests verify both state changes and database records

Compliance Check

  • Coding Standards: ✓ Code formatted with Pint
  • Project Structure: ✓ Files in correct locations per architecture
  • Testing Strategy: ✓ Feature tests with Pest/Volt
  • All ACs Met: ✓ 22/22 acceptance criteria validated

Refactoring Performed

No refactoring performed - implementation is clean and follows best practices.

Improvements Checklist

  • Race condition prevention with DB locking
  • Double validation (pre + in-transaction)
  • Email queuing for async delivery
  • Proper loading states in UI
  • Full bilingual support
  • Audit logging for client actions
  • Consider adding a test for admin-only notification when no admin exists (edge case - currently silently skips)
  • Consider extracting the 1-per-day check to a query scope on Consultation model for reuse

Security Review

Status: PASS

  • ✓ Authentication required via route middleware (auth, active)
  • ✓ Authorization implicit (client can only book for themselves via auth()->id())
  • ✓ Input validation with Laravel validator
  • ✓ SQL injection prevented via Eloquent ORM
  • ✓ XSS prevented via Blade escaping
  • ✓ CSRF protection via Livewire
  • ✓ Race condition prevention via pessimistic locking
  • ✓ Problem summary has max length (2000 chars) preventing payload attacks

Performance Considerations

Status: PASS

  • ✓ Emails queued (not blocking request)
  • ✓ Database queries are indexed (user_id, booking_date, status)
  • ✓ No N+1 query issues in the booking flow
  • ✓ Reasonable transaction scope (creates one consultation, logs one entry)

Files Modified During Review

None - no modifications needed.

Gate Status

Gate: PASS → docs/qa/gates/3.4-booking-request-submission.yml
