How do you enforce architectural constraints using Pest PHP Architecture Testing in Laravel?
❓ Interview Prompt: Explain Pest PHP Architecture Testing, arch() expectations, protecting layer boundaries, and preventing architectural drift.
Pest PHP Architecture Testing allows teams to define automated architectural rules in PHPUnit/Pest test suites, preventing codebase degradation over time:
Example Architectural Constraints:
•
Controllers must only use Service or Model classes.
•
Models must extend 'IlluminateDatabaseEloquentModel'.
•
Debug functions ('dd()', 'dump()') must never be committed to repository history!
Code Implementation Example
php
<?php
// tests/Architecture/ArchitectureTest.php
arch('controllers must not access request global helpers directly')
->expect('AppHttpControllers')
->not->toUse(['dd', 'dump', 'die']);
arch('models must extend Eloquent Model')
->expect('AppModels')
->toExtend('IlluminateDatabaseEloquentModel');💡Enforcing architectural boundary rules using Pest PHP Architecture Testing.
🎯 Interview Key Takeaway
Use Pest PHP Architecture Testing (arch()) to automatically enforce codebase architectural boundaries in CI pipelines.
