### Required Consultation Model Fields
|
|
This story assumes the following fields exist on the `Consultation` model (from Epic 3):
|
|
- `id` - Unique identifier (booking reference)
|
|
- `user_id` - Foreign key to User
|
|
- `scheduled_date` - Date of consultation
|
|
- `scheduled_time` - Time of consultation
|
|
- `duration` - Duration in minutes (default: 45)
|
|
- `status` - Consultation status ('pending', 'approved', 'rejected', etc.)
|
|
- `type` - 'free' or 'paid'
|
|
- `payment_amount` - Amount for paid consultations (nullable)
|
|
|
|
### Views to Create
|
|
- `resources/views/emails/booking/approved/ar.blade.php` - Arabic template
|
|
- `resources/views/emails/booking/approved/en.blade.php` - English template
|
|
|
|
### Mailable Class
|
|
Create `app/Mail/BookingApprovedEmail.php`:
|
|
|
|
```php
|
|
<?php
|
|
|
|
namespace App\Mail;
|
|
|
|
use App\Models\Consultation;
|
|
use Illuminate\Bus\Queueable;
|
|
use Illuminate\Mail\Attachment;
|
|
use Illuminate\Mail\Mailable;
|
|
use Illuminate\Mail\Mailables\Content;
|
|
use Illuminate\Mail\Mailables\Envelope;
|
|
use Illuminate\Queue\SerializesModels;
|
|
|
|
class BookingApprovedEmail extends Mailable
|
|
{
|
|
use Queueable, SerializesModels;
|
|
|
|
public function __construct(
|
|
public Consultation $consultation,
|
|
public string $icsContent,
|
|
public ?string $paymentInstructions = null
|
|
) {}
|
|
|
|
public function envelope(): Envelope
|
|
{
|
|
$locale = $this->consultation->user->preferred_language ?? 'ar';
|
|
$subject = $locale === 'ar'
|
|
? 'تمت الموافقة على استشارتك'
|
|
: 'Your Consultation Has Been Approved';
|
|
|
|
return new Envelope(subject: $subject);
|
|
}
|
|
|
|
public function content(): Content
|
|
{
|
|
$locale = $this->consultation->user->preferred_language ?? 'ar';
|
|
|
|
return new Content(
|
|
markdown: "emails.booking.approved.{$locale}",
|
|
with: [
|
|
'consultation' => $this->consultation,
|
|
'user' => $this->consultation->user,
|
|
'paymentInstructions' => $this->paymentInstructions,
|
|
],
|
|
);
|
|
}
|
|
|
|
public function attachments(): array
|
|
{
|
|
return [
|
|
Attachment::fromData(fn() => $this->icsContent, 'consultation.ics')
|
|
->withMime('text/calendar'),
|
|
];
|
|
}
|
|
}
|
|
```
|
|
|
|
### Trigger Mechanism
|
|
Add observer or listener to send email when consultation status changes to 'approved':
|
|
|
|
```php
|
|
// Option 1: In Consultation model boot method or observer
|
|
use App\Mail\BookingApprovedEmail;
|
|
use App\Services\CalendarService;
|
|
use Illuminate\Support\Facades\Mail;
|
|
|
|
// In ConsultationObserver or model event
|
|
public function updated(Consultation $consultation): void
|
|
{
|
|
if ($consultation->wasChanged('status') && $consultation->status === 'approved') {
|
|
$icsContent = app(CalendarService::class)->generateIcs($consultation);
|
|
|
|
$paymentInstructions = null;
|
|
if ($consultation->type === 'paid') {
|
|
$paymentInstructions = $this->getPaymentInstructions($consultation);
|
|
}
|
|
|
|
Mail::to($consultation->user)
|
|
->queue(new BookingApprovedEmail($consultation, $icsContent, $paymentInstructions));
|
|
}
|
|
}
|
|
```
|
|
|
|
### Payment Instructions
|
|
For paid consultations, include payment details:
|
|
- Amount to pay
|
|
- Payment methods accepted
|
|
- Payment deadline (before consultation)
|
|
- Bank transfer details or payment link
|
|
|
|
## Testing Guidance
|
|
|
|
### Test Approach
|
|
- Unit tests for Mailable class
|
|
- Feature tests for trigger mechanism (observer)
|
|
- Integration tests for email queue
|
|
|
|
### Key Test Scenarios
|
|
|
|
```php
|
|
use App\Mail\BookingApprovedEmail;
|
|
use App\Models\Consultation;
|
|
use App\Models\User;
|
|
use App\Services\CalendarService;
|
|
use Illuminate\Support\Facades\Mail;
|
|
|
|
it('queues email when consultation is approved', function () {
|
|
Mail::fake();
|
|
|
|
$consultation = Consultation::factory()->create(['status' => 'pending']);
|
|
$consultation->update(['status' => 'approved']);
|
|
|
|
Mail::assertQueued(BookingApprovedEmail::class, function ($mail) use ($consultation) {
|
|
return $mail->consultation->id === $consultation->id;
|
|
});
|
|
});
|
|
|
|
it('does not send email when status changes to non-approved', function () {
|
|
Mail::fake();
|
|
|
|
$consultation = Consultation::factory()->create(['status' => 'pending']);
|
|
$consultation->update(['status' => 'rejected']);
|
|
|
|
Mail::assertNotQueued(BookingApprovedEmail::class);
|
|
});
|
|
|
|
it('includes ics attachment', function () {
|
|
$consultation = Consultation::factory()->approved()->create();
|
|
$icsContent = app(CalendarService::class)->generateIcs($consultation);
|
|
|
|
$mailable = new BookingApprovedEmail($consultation, $icsContent);
|
|
|
|
expect($mailable->attachments())->toHaveCount(1);
|
|
expect($mailable->attachments()[0]->as)->toBe('consultation.ics');
|
|
});
|
|
|
|
it('uses Arabic template for Arabic-preferring users', function () {
|
|
$user = User::factory()->create(['preferred_language' => 'ar']);
|
|
$consultation = Consultation::factory()->approved()->for($user)->create();
|
|
$icsContent = app(CalendarService::class)->generateIcs($consultation);
|
|
|
|
$mailable = new BookingApprovedEmail($consultation, $icsContent);
|
|
|
|
expect($mailable->content()->markdown)->toBe('emails.booking.approved.ar');
|
|
});
|
|
|
|
it('uses English template for English-preferring users', function () {
|
|
$user = User::factory()->create(['preferred_language' => 'en']);
|
|
$consultation = Consultation::factory()->approved()->for($user)->create();
|
|
$icsContent = app(CalendarService::class)->generateIcs($consultation);
|
|
|
|
$mailable = new BookingApprovedEmail($consultation, $icsContent);
|
|
|
|
expect($mailable->content()->markdown)->toBe('emails.booking.approved.en');
|
|
});
|
|
|
|
it('includes payment instructions for paid consultations', function () {
|
|
$consultation = Consultation::factory()->approved()->create([
|
|
'type' => 'paid',
|
|
'payment_amount' => 150.00,
|
|
]);
|
|
$icsContent = app(CalendarService::class)->generateIcs($consultation);
|
|
$paymentInstructions = 'Please pay 150 ILS before your consultation.';
|
|
|
|
$mailable = new BookingApprovedEmail($consultation, $icsContent, $paymentInstructions);
|
|
|
|
expect($mailable->paymentInstructions)->toBe($paymentInstructions);
|
|
});
|
|
|
|
it('excludes payment instructions for free consultations', function () {
|
|
$consultation = Consultation::factory()->approved()->create(['type' => 'free']);
|
|
$icsContent = app(CalendarService::class)->generateIcs($consultation);
|
|
|
|
$mailable = new BookingApprovedEmail($consultation, $icsContent);
|
|
|
|
expect($mailable->paymentInstructions)->toBeNull();
|
|
});
|
|
```
|
|
|
|
### Edge Cases to Test
|
|
- User with null `preferred_language` defaults to 'ar'
|
|
- Consultation without payment_amount for paid type (handle gracefully)
|
|
- Email render test with `$mailable->render()`
|

## QA Results
|
|
|
|
### Review Date: 2026-01-02
|
|
|
|
### Reviewed By: Quinn (Test Architect)
|
|
|
|
### Code Quality Assessment
|
|
|
|
**Overall: Excellent** - The implementation is well-structured, follows Laravel best practices, and demonstrates good architectural decisions.
|
|
|
|
**Strengths:**
|
|
- **Mailable Design**: Clean separation of concerns with proper use of Laravel's Mailable components (Envelope, Content, attachments)
|
|
- **Queue Support**: Correctly implements `ShouldQueue` for background processing
|
|
- **Observer Pattern**: Appropriate use of Eloquent Observer for decoupled event handling
|
|
- **Bilingual Support**: Proper RTL support in Arabic template with `dir="rtl"` attribute
|
|
- **Null Safety**: Good use of null coalescing operators for optional fields
|
|
- **Helper Methods**: Well-organized helper methods (`getFormattedDate`, `getFormattedTime`, `getConsultationTypeLabel`) improve testability
|
|
|
|
**Architecture Notes:**
|
|
- The `BookingApprovedMail` correctly uses dependency injection for the consultation model
|
|
- Payment instructions are properly isolated in the Observer, keeping the Mailable focused on presentation
|
|
- The CalendarService integration is appropriately handled through dependency injection in the Observer
|
|
|
|
### Refactoring Performed
|
|
|
|
None required. The code quality is high and follows established patterns.
|
|
|
|
### Compliance Check
|
|
|
|
- Coding Standards: ✓ Passes Pint formatting, follows naming conventions
|
|
- Project Structure: ✓ Files placed in correct locations per architecture
|
|
- Testing Strategy: ✓ Comprehensive Pest tests with proper factory usage
|
|
- All ACs Met: ✓ All acceptance criteria covered (see traceability below)
|
|
|
|
### Requirements Traceability
|
|
|
|
| AC | Requirement | Test Coverage |
|
|
|----|-------------|---------------|
|
|
| Trigger | Email sent on booking approval | `queues email when consultation is approved`, `does not send email when status changes to non-approved`, `does not send email when consultation is created as approved`, `does not send email when other fields change on approved consultation` |
|
|
| Content: Title | "Your consultation has been approved" | `email renders without errors in Arabic/English` |
|
|
| Content: Date/Time | Confirmed date and time | `date is formatted as d/m/Y for Arabic users`, `date is formatted as m/d/Y for English users`, `time is formatted as h:i A` |
|
|
| Content: Duration | 45 minutes | `duration defaults to 45 minutes` |
|
|
| Content: Type | Consultation type (free/paid) | `consultation type label is correct in Arabic/English` |
|
|
| Content: Payment | Payment info for paid | `includes payment instructions for paid consultations`, `paid consultation email includes payment amount`, `excludes payment instructions for free consultations`, `free consultation email does not include payment section` |
|
|
| Attachment | .ics calendar file | `includes ics attachment` |
|
|
| Language | Client's preferred language | `uses Arabic template for Arabic-preferring users`, `uses English template for English-preferring users`, `defaults to Arabic when preferred_language is ar` |
|
|
| Subject | Correct subject line | `has correct Arabic subject`, `has correct English subject` |
|
|
|
|
### Test Architecture Assessment
|
|
|
|
- **Test Count**: 25 tests with 37 assertions
|
|
- **Test Levels**: Appropriate mix of unit tests (Mailable class) and integration tests (Observer behavior)
|
|
- **Coverage**: All acceptance criteria have corresponding test coverage
|
|
- **Factory Usage**: Proper use of factory states (`approved()`, `pending()`, `free()`, `paid()`)
|
|
- **Edge Cases**: All documented edge cases covered
|
|
|
|
### Improvements Checklist
|
|
|
|
- [x] All acceptance criteria implemented and tested
|
|
- [x] Bilingual templates with RTL support
|
|
- [x] Queue-based email delivery
|
|
- [x] Observer-based trigger mechanism
|
|
- [x] ICS attachment generation
|
|
- [x] Payment instructions for paid consultations
|
|
- [x] Code formatted with Pint
|
|
|
|
### Security Review
|
|
|
|
✓ **No security concerns identified**
|
|
- Email is only sent to the consultation owner (user relationship)
|
|
- No sensitive data exposure in email templates
|
|
- Payment amounts are properly formatted without exposing internal IDs
|
|
- No user-controllable input that could lead to injection
|
|
|
|
### Performance Considerations
|
|
|
|
✓ **No performance concerns**
|
|
- Email is queued via `ShouldQueue`, preventing blocking during approval
|
|
- Observer uses `loadMissing()` to prevent N+1 queries
|
|
- ICS generation is lightweight and inline
|
|
|
|
### Files Modified During Review
|
|
|
|
None - code quality was satisfactory.
|
|
|
|
### Gate Status
|
|
|
|
Gate: **PASS** → `docs/qa/gates/8.4-booking-approved-email.yml`
|
|
|
|
### Recommended Status
