All files must have declare(strict_types=1) at top. Run quality checks before every commit.

Architecture Tests (Pest)

<?php

declare(strict_types=1);

arch('actions are invokable')
    ->expect('App\Actions')
    ->toHaveMethod('__invoke');

arch('actions live in Actions namespace')
    ->expect('App\Actions')
    ->toBeClasses()
    ->toOnlyBeUsedIn('App\Actions', 'App\Http', 'App\Jobs', 'App\Listeners');

    ->expect('App\Actions')
    ->not->toUse('Illuminate\Database\Eloquent\Model');

<?php

declare(strict_types=1);

    ->expect('App\Data')
    ->toHaveSuffix('Data')
    ->ignoring('App\Data\Data', 'App\Data\Concerns');

arch('exceptions end with Exception suffix')
    ->expect('App\Exceptions')
    ->toHaveSuffix('Exception')
    ->ignoring('App\Exceptions\Concerns');

tests/​Architecture/​ModelsTest.php

<?php

declare(strict_types=1);

arch('models use custom query builders')
    ->expect('App\Models')
    ->toHaveMethod('newEloquentBuilder');

arch('models do not use local scopes')
    ->expect('App\Models')
    ->not->toHaveMethod('scope*');

Static Analysis (PHPStan)

Installation

composer require phpstan/​phpstan --dev
composer require phpstan/​phpstan-strict-rules --dev
composer require larastan/​larastan --dev

Configuration

phpstan.neon

includes:
    - vendor/​larastan/​larastan/​extension.neon
    - vendor/​phpstan/​phpstan-strict-rules/​rules.neon

parameters:
    level: 8
    paths:
        - app
        - tests
    excludePaths:
        - app/​Providers/​TelescopeServiceProvider.php
    checkMissingIterableValueType: true
    checkGenericClassInNonGenericObjectType: true
    reportUnmatchedIgnoredErrors: false

Run

./​vendor/​bin/​phpstan analyse

Code Style (Laravel Pint)

Installation

composer require laravel/​pint --dev

Configuration

pint.json

{
    "preset": "laravel",
    "rules": {
        "simplified_null_return": true,

        "ordered_imports": {
            "sort_algorithm": "alpha"
        }
    }
}

Run

./​vendor/​bin/​pint
./​vendor/​bin/​pint --test  # Check only

Test Coverage

Enable Coverage (Pest)

phpunit.xml

<coverage>
    <report>
        <html outputDirectory="coverage"/>
        <text outputFile="php://stdout"/>
    </​report>
</​coverage>

Run with Coverage

./​vendor/​bin/​pest --coverage
./​vendor/​bin/​pest --coverage --min=80  # Enforce minimum

CI/​CD Checks

GitHub Actions Example

on: [push, pull_request]

jobs:
  test:
    runs-on: ubuntu-latest

    steps:
      - uses: actions/​checkout@v3

      - name: Setup PHP
        uses: shivammathur/​setup-php@v2
        with:
          php-version: 8.4
          extensions: dom, curl, libxml, mbstring, zip, pcntl, pdo, sqlite, pdo_sqlite
          coverage: xdebug

      - name: Install Dependencies
        run: composer install --prefer-dist --no-interaction

        run: ./​vendor/​bin/​pest --coverage --min=80

Pre-commit Hooks

Installation

composer require brainmaestro/​composer-git-hooks --dev

Configuration

composer.json

{
    "extra": {
        "hooks": {
            "pre-commit": [
                "./​vendor/​bin/​pint",
                "./​vendor/​bin/​phpstan analyse",
                "./​vendor/​bin/​pest"
            ]
        }
    },
    "scripts": {
        "post-install-cmd": "vendor/​bin/​cghooks add --ignore-lock",
        "post-update-cmd": "vendor/​bin/​cghooks update"
    }
}

Quality Metrics

What to Track

• Test coverage - Aim for 80%+
• PHPStan level - Level 8 (max)
• Architecture test pass rate - 100%
• Code style violations - 0

Regular Reviews

• Weekly - Check test coverage trends
• Per PR - Run all quality checks
• Monthly - Review architecture compliance
• Release - Full quality audit

Common Issues to Watch

Anti-patterns

• Domain logic in controllers
• Using scopes instead of builders
• Missing strict types declaration
• Passing primitives instead of DTOs
• Jobs/​Listeners with domain logic

Type Safety

• Missing return types
• Missing parameter types
• Missing property types
• Untyped arrays/​collections

Testing

• Missing feature tests for endpoints
• Missing unit tests for actions
• Low coverage on critical paths
• Brittle tests (too many mocks)

Enforcement Strategy

1. Architecture tests - Automated checks
2. PR reviews - Manual verification
3. CI/​CD gates - Block failing builds
4. Team standards - Document + training
5. Pair programming - Share knowledge
