+## Testing
+
+This template uses `pytest` and `unittest` for testing.
+
+### Running Tests
+
+To run the unit tests:
+
+```bash
+uv run python -m unittest discover tests
+```
+
+Or if you prefer `pytest`:
+
+```bash
+uv run pytest
+```
+
+## Code Review Challenge
+
+This template is designed to test AI-powered code review tools (like Junie, Copilot, or Qodo). It includes:
+- A modular structure that allows for architectural reviews.
+- Strategic use of type hints.
+- Centralized error handling.
+- Placeholder tests and TODOs to see if they are flagged.
+- A "Manager" pattern that can be critiqued.
+
+### Areas for Reviewers to Focus On:
+1. **Architecture:** Is the `LambdaManager` too heavy? Should the validation logic be more decoupled?
+2. **Security:** Are secrets handled correctly? (Check `_validate_api_key` in `lambda_function.py`).
+3. **Typing:** Are all `Any` types necessary?
+4. **Testing:** Is the test coverage sufficient? Are the mocks appropriate?
+
