🛠️ Migration Changes

1. Configuration Updates

✅ phpunit.xml Schema Update

<!-- BEFORE -->
xsi:noNamespaceSchemaLocation="https://schema.phpunit.de/12.0/phpunit.xsd"

<!-- AFTER -->
xsi:noNamespaceSchemaLocation="https://schema.phpunit.de/12.3/phpunit.xsd"

✅ Bootstrap File Creation

• New: tests/bootstrap.php
• Features: Autoloading, test environment setup, utility functions
• Configuration: SQLite in-memory database for testing

2. Test File Modernization

✅ PSR-4 Namespace Implementation

All test files now use proper PSR-4 namespacing:

<?php

declare(strict_types=1);

namespace DeskMoloni\Tests;

use PHPUnit\Framework\TestCase;

✅ Files Updated:

1. tests/ClientPortalTest.php - ✅ Namespace + strict types
2. tests/ClientSyncServiceTest.php - ✅ Namespace + strict types
3. tests/IntegrationTest.php - ✅ Namespace + strict types
4. tests/QueueProcessorTest.php - ✅ Namespace + strict types
5. tests/TestCase.php - ✅ Namespace + strict types

3. Dependency Management

✅ Composer Configuration

{
  "require-dev": {
    "phpunit/phpunit": "^12.0"
  },
  "require": {
    "php": "^8.3"
  }
}

✅ Autoloading Compliance

Fixed PSR-4 compliance warnings during composer install.

🔧 Technical Improvements

Modern PHP Features

• Strict Types: All test files now use declare(strict_types=1)
• Type Declarations: Improved type safety throughout test suite
• Modern Assertions: Compatible with PHPUnit 12.x assertion methods

Testing Environment

• Bootstrap: Comprehensive test environment initialization
• Autoloading: Both Composer and manual fallback autoloading
• Database: SQLite in-memory testing database
• Configuration: Environment variables and constants setup

Code Quality

• Syntax Clean: All PHP files pass syntax validation
• Namespace Clean: No PSR-4 autoloading violations
• Structure Clean: Organized test directory structure
