# Changelog # Changelog
## 2024-12-30 - 1.3.0 - feat(Assertion)
Refactor Assertion class for better error handling and code clarity
- Improved method runCheck to better handle async and sync execution
- Enhanced getObjectToTestReference to handle undefined or null values gracefully
- Refactored error message logic for clarity and added more descriptive fail messages
- Added arrayItem method for better handling of array index access
- Improved structure by integrating consistent error handling in assertion methods
## 2024-08-24 - 1.2.1 - fix(Assertion) ## 2024-08-24 - 1.2.1 - fix(Assertion)
Refactor methods for setting failure and success messages Refactor methods for setting failure and success messages
