I have full CRUD testing coverage, including success and failure scenarios, an isolated test environment, and database resets. I understand the differences between HTTP code, test the API as a whole, not individual functions, and use a plan-to-implement approach. The project is ready for further expansion with pagination, validation, and JWT authorization.</p> <p>Project link: <a href="https://github.com/DamianMarchewka/Task-Manager-API" rel="noopener noreferrer">https://github.com/DamianMarchewka/Task-Manager-API</a><br> Feedback and constructive criticism are welcome.</p> api python showdev testing
