+## Testing PHP 8.3 Compatibility
+
+The framework includes a PHPUnit test suite specifically for validating PHP 8.3 compatibility. To run these tests:
+
+```bash
+# Install composer dependencies if not already done
+bin/composer-install
+
+# Run the PHP 8.3 compatibility tests
+vendor/bin/phpunit
+```
+
+This will execute tests that verify key components work correctly with PHP 8.3 including:
+- Type system compatibility (nullable and union types)
+- Trait implementation compatibility
+- Core framework functionality
+- Platform-specific features
+- Twig integration
+
 ## Bundling JS and Compiling SCSS
 
 In our development environment, we use **Gulp** to bundle **JavaScript** and compile **SCSS** with the capability of `watch` so that any change on target files will automatically trigger the recompilation.

+# PHP 8.3 Compatibility Test Suite for Gantry5
+
+This test suite is designed to validate Gantry5 compatibility with PHP 8.3. It includes tests for critical components that may be affected by PHP 8.3 changes.
+
+## Test Categories
+
+### Framework Tests
+Tests core Gantry framework functionality:
+- Gantry instance creation and container access
+- Service registration and retrieval 
+- Debug functionality
+
+### Platform Tests
+Tests platform-specific functionality:
+- Platform detection
+- Joomla-specific features
+- WordPress-specific features
+
+### Component Tests
+Tests individual components:
+- PHP 8.3 type system (nullable and union types)
+- Trait compatibility
+- Twig integration (filters, functions, extensions)
+
+## Running Tests
+
+Run the tests using PHPUnit:
+
+```bash
+# From the Gantry5 root directory
+vendor/bin/phpunit
+```
+
+## Adding New Tests
+
+To add new PHP 8.3 compatibility tests:
+
+1. Create a new test file in the appropriate directory:
+   - `tests/php83/Framework/` for core framework tests
+   - `tests/php83/Platform/` for platform-specific tests
+   - `tests/php83/Component/` for component tests
+
+2. Tests should extend `PHPUnit\Framework\TestCase`
+
+3. Focus on PHP 8.3 specific features like:
+   - Proper handling of nullable and union types
+   - Deprecation warnings or errors
+   - New language feature compatibility
+
+## Reporting Issues
+
+If you find PHP 8.3 compatibility issues, please open an issue on GitHub with:
+- Detailed description of the issue
+- Steps to reproduce
+- PHP 8.3 error messages or warnings
+- Suggestions for fixes if available
