Testing Laravel Apps Built with AI

AI tools generate Eloquent models with incorrect relationship definitions, missing eager loading, and query scopes that produce wrong results. BelongsToMany relationships may reference the wrong pivot table, HasManyThrough relationships may join on incorrect keys, and polymorphic relationships may not resolve the correct model type.

Mass assignment protection is frequently misconfigured. AI tools either guard too many fields, preventing legitimate updates, or too few fields, exposing the application to mass assignment vulnerabilities. Mutators and accessors may transform data incorrectly, causing display issues throughout the application.

Testers interact with every data-driven feature in your Laravel app, creating records, updating them, and verifying that related data displays correctly. They catch the symptoms of Eloquent misconfigurations that unit tests on an empty database would never reveal.

Blade templates generated by AI often have broken @section and @yield directives, incorrect conditional rendering, and missing CSRF tokens on forms. These issues cause pages to render with missing content, forms to fail on submission, and layouts to break on specific pages.

Livewire components are particularly problematic in AI-generated code. Wire model bindings may not sync correctly, component lifecycle hooks may execute in unexpected order, and real-time validation may not trigger when expected. AI tools also frequently generate Livewire components that re-render too aggressively, causing input fields to lose focus.

Testers verify that every page renders completely, that all forms submit successfully, and that Livewire interactions feel responsive and correct. They test edge cases like rapid input, concurrent form submissions, and browser back/forward navigation.

Testers evaluate your complete Laravel application including authentication with Laravel Breeze or Jetstream, authorization with Gates and Policies, queued job results, notification delivery, and file storage operations. They verify that scheduled tasks produce correct outcomes and that caching does not serve stale data.

For Laravel apps with API endpoints, testers verify that Sanctum or Passport authentication works correctly, that rate limiting is properly applied, and that API responses follow the expected format. They test both the web and API surfaces of your application.
