+
+## 📊 Upgrade Summary
+
+### Version Changes
+| Component | Previous | New | Status |
+|-----------|----------|-----|--------|
+| PHPUnit Core | 9.6.25 | 12.3.10 | ✅ Updated |
+| PHP Code Coverage | 9.2.32 | 12.3.7 | ✅ Updated |

+| Sebastian Components | v3-5 | v6-8 | ✅ Updated |
+
+## 🛠️ Migration Changes
+
+### 1. Configuration Updates
+
+#### ✅ phpunit.xml Schema Update
+```xml
+<!-- 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
+<?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
+```json
+{
+  "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
+
+## 🧪 Test Suite Status
+
+### Test Files Summary
+| Test File | Status | Tests | Coverage |
+|-----------|--------|-------|----------|
+| ClientPortalTest | ✅ Ready | 20+ methods | API, Security, Performance |
+| ClientSyncServiceTest | ✅ Ready | 15+ methods | Sync, Conflicts, Errors |  
+| IntegrationTest | ✅ Ready | 12+ methods | End-to-end workflows |
+| QueueProcessorTest | ✅ Ready | 18+ methods | Queue, Retry, Health |
+
+### Test Categories
+- **Unit Tests**: Service layer testing with mocks
+- **Integration Tests**: Full workflow testing
