• Set up Jest as the unit testing framework with TypeScript support (using ts-jest or equivalent).
• Configure Jest to correctly transpile and run TypeScript test files.
• Write comprehensive unit tests covering all major modules and features.
• Refactor existing code as needed to enable effective testing.
• Ensure code coverage is at least 80% across the codebase.
• Integrate Jest tests into the CI workflow for automated runs on pull requests.
• Add clear documentation on how to run Jest tests locally and interpret results.
