Add comprehensive tests for Parks API and models
- Implemented extensive test cases for the Parks API, covering endpoints for listing, retrieving, creating, updating, and deleting parks. - Added tests for filtering, searching, and ordering parks in the API. - Created tests for error handling in the API, including malformed JSON and unsupported methods. - Developed model tests for Park, ParkArea, Company, and ParkReview models, ensuring validation and constraints are enforced. - Introduced utility mixins for API and model testing to streamline assertions and enhance test readability. - Included integration tests to validate complete workflows involving park creation, retrieval, updating, and deletion.
