## Test Statistics

- **Total Test Classes**: 16
- **Unit Tests**: 15 classes
- **Feature Tests**: 1 class
- **Test Methods**: ~50+ individual test methods

## Test Categories

### Service Layer Tests

Tests all service classes with mocked dependencies:

- Authentication service (token retrieval, refresh)
- Payment service (validation, initiation, wallet)
- Transaction service (queries, refunds, lists)
- OTP verification service (OTP verification, pares handling)

### Repository Tests

Tests data access layer:

- Create, read, update operations
- Find by transaction ID, basket ID, pares
- Status updates

### Model Tests

Tests model functionality:

- Status constants and helper methods
- Status transition methods
- Payment method constants

### Event Tests

Tests event system:

- Event instantiation
- Event data integrity
- Event dispatching

### Integration Tests

Tests complete payment flows:

- Card payment with OTP verification
- Payment validation failures
- Wallet payment flows (EasyPaisa, UPaisa)

## Running Tests

```bash
# Run all tests
php artisan test

# Run PayFast tests only
php artisan test --filter PayFast

# Run with coverage
php artisan test --coverage

# Run specific test class
php artisan test tests/Unit/PayFast/Services/AuthenticationServiceTest.php
```

## Test Quality

- **Mocking**: All external dependencies are mocked
- **Isolation**: Each test is independent
- **Coverage**: All major functionality covered
- **PSR-12**: All tests follow coding standards
- **Type Safety**: Strict types enabled
- **Documentation**: Tests are well-documented

## Key Test Scenarios

### Authentication

- Successful token retrieval
- Token refresh
- Authentication failures

### Payment Processing

- Customer validation
- Transaction initiation
- Wallet payment validation
- Payment failures

### OTP Verification

- OTP verification and pares storage
- Payment not found scenarios
- Invalid status handling

### Transaction Completion

- Complete transaction from pares
- Auth failures
- Transaction failures

### Payment Status Transitions

- Pending → Validated
- Validated → OTP Verified
- OTP Verified → Completed
- Any status → Failed

## Test Data

Tests use:

- **Factories**: `ProcessPaymentFactory` for test data
- **Mocks**: Mockery for service mocking
- **Faker**: For generating test data
- **Config**: Test configuration in `TestCase::setUp()`

## Continuous Integration

Tests are ready for CI/CD:

- No external API calls
- All dependencies mocked
- Database migrations included
- Environment variables configured

## Future Test Additions

Potential areas for additional tests:

- [ ] More edge cases for payment flows
- [ ] Performance tests
- [ ] Stress tests
- [ ] Security tests
- [ ] Integration with real PayFast API (staging)

## Notes

- All tests use `RefreshDatabase` trait for clean state
- Tests are fast (no real API calls)
- Mockery is used for all external dependencies
- Events are faked to avoid side effects
- Factories provide consistent test data
