# Queue worker (required for export functionality)
php artisan queue:work

For production setup with Nginx/Apache, see INSTALLATION.md.

---

⚙️ Configuration

Queue Workers

Export functionality requires a queue worker to be running:

# Local development (sync queue)
QUEUE_CONNECTION=sync

# Production (Redis recommended)
QUEUE_CONNECTION=redis

For production, use a process manager like Supervisor:

[program:invoiceplane-worker]
process_name=%(program_name)s_%(process_num)02d
command=php /path/to/artisan queue:work redis --sleep=3 --tries=3 --max-time=3600
autostart=true
autorestart=true
stopasgroup=true
killasgroup=true
user=www-data
numprocs=8
redirect_stderr=true
stdout_logfile=/path/to/worker.log
stopwaitsecs=3600

Peppol Configuration

To enable Peppol e-invoicing, configure in .env:

PEPPOL_E_INVOICE_BE_API_KEY=your-api-key
PEPPOL_E_INVOICE_BE_BASE_URL=https://api.e-invoice.be

See PEPPOL_ARCHITECTURE.md for complete setup.

🛠️ Development

Running Tests

Tests run inside the Docker workspace container — the database is only reachable there:

# Run all tests
docker exec ivpldock-workspace-1 bash -c "cd /var/www/projects/ip2 && php artisan test"

# Run specific test file
docker exec ivpldock-workspace-1 bash -c "cd /var/www/projects/ip2 && php artisan test Modules/Invoices/Tests/Feature/InvoicesTest.php"

# Fall back to phpunit for full exception traces on failure
docker exec ivpldock-workspace-1 bash -c "cd /var/www/projects/ip2 && vendor/bin/phpunit Modules/Invoices/Tests/Feature/InvoicesTest.php"

Or use the Makefile shorthand (see Makefile for available targets).

See RUNNING_TESTS.md for advanced testing.

Code Quality

# Format code with Laravel Pint
vendor/bin/pint

# Run static analysis
vendor/bin/phpstan analyse

# Run Rector for automated refactoring
vendor/bin/rector process --dry-run

Asset Development

# Development build with hot reload
yarn dev

# Production build
yarn build

# Watch for changes
yarn dev --watch

Database Seeding

# Seed all seeders
php artisan db:seed

# Seed specific seeder
php artisan db:seed --class=InvoiceSeeder

# Fresh migration with seeding
php artisan migrate:fresh --seed

See SEEDING.md for custom seeding.

🧪 Testing

InvoicePlane v2 includes comprehensive PHPUnit tests:

Test Structure

Modules/
  ├── Invoices/Tests/
  │   ├── Unit/          # Unit tests
  │   ├── Feature/       # Feature tests
  │   └── Integration/   # Integration tests
  ├── Quotes/Tests/
  └── ...

Writing Tests

All tests follow these conventions:

• Test methods start with it_ (e.g., it_creates_invoice)
• Use #[Test] attribute
• Follow Arrange-Act-Assert pattern
• Extend appropriate base test case

Example:

#[Test]
public function it_creates_invoice(): void
{
    /* Arrange */
    $customer = Customer::factory()->create();
    
    /* Act */
    $invoice = Invoice::factory()->create(['customer_id' => $customer->id]);
    
    /* Assert */
    $this->assertDatabaseHas('invoices', ['id' => $invoice->id]);
}
