|
||||
- ✅ Bidirectional sync with conflict resolution
|
||||
- ✅ Webhook processing → Queue → Sync
|
||||
- ✅ Bulk operations and performance
|
||||
- ✅ Error handling and recovery
|
||||
- ✅ Security and validation
|
||||
|
||||
## 🛠️ TECHNICAL FEATURES IMPLEMENTED
|
||||
|
||||
### Modern PHPUnit 12.3 Syntax
|
||||
- ✅ PHP 8+ Attributes instead of docblock annotations
|
||||
- ✅ `#[Test]`, `#[Group]`, `#[DataProvider]` attributes
|
||||
- ✅ `#[CoversClass]` for proper coverage tracking
|
||||
- ✅ Strict type declarations (`declare(strict_types=1)`)
|
||||
|
||||
### Testing Best Practices
|
||||
- ✅ **Mocking:** External dependencies (Redis, APIs, Database)
|
||||
- ✅ **Data Providers:** Parameterized testing for multiple scenarios
|
||||
- ✅ **Fixtures:** Consistent test data setup
|
||||
- ✅ **Teardown:** Proper cleanup to prevent test interference
|
||||
- ✅ **Assertions:** Comprehensive validation at multiple levels
|
||||
|
||||
### Error & Edge Case Coverage
|
||||
- ✅ API failures and timeouts
|
||||
- ✅ Invalid data handling
|
||||
- ✅ Network connectivity issues
|
||||
- ✅ Concurrent modification conflicts
|
||||
- ✅ Queue overflow scenarios
|
||||
- ✅ Security validation failures
|
||||
|
||||

## 🚀 IMPLEMENTATION HIGHLIGHTS
|
||||
|
||||
### Advanced Testing Patterns
|
||||
```php
|
||||
// Modern PHPUnit 12 syntax
|
||||
#[Test]
|
||||
#[Group('unit')]
|
||||
#[DataProvider('webhookPayloadProvider')]
|
||||
public function testWebhookValidation(array $payload, bool $expected): void
|
||||
|
||||
// Comprehensive mocking
|
||||
$this->api_client_mock
|
||||
->expects($this->once())
|
||||
->method('create_customer')
|
||||
->willReturn(['valid' => 1, 'data' => ['customer_id' => '999']]);
|
||||
|
||||
// Real-world scenarios
|
||||
public function testCompleteCustomerToInvoiceWorkflow(): void
|
||||
```
|
||||
|
||||
### Business Logic Testing
|
||||
- **Scenario-based:** Real user workflows from registration to invoice
|
||||
- **Integration:** Multi-service coordination testing
|
||||
- **Feature:** End-to-end business process validation
|
||||
- **Performance:** Bulk operations and scalability testing
