How To Build a Simple API with Flask and Unit Test it
Blog post from Pybites
REST has become the default architectural style for designing web services, enabling interoperability between computer systems through stateless operations. The article explores implementing REST APIs using Flask, with a focus on a House Inventory Tracker as a practical example. It highlights the simplicity of creating and testing CRUD operations via HTTP methods, using an in-memory list for storage, and emphasizes the necessity of security and authentication in such implementations. The testing process is discussed in two parts: manual testing with curl commands and automated testing using Flask's unittest framework, each offering insights into ensuring API functionality and data integrity. The author shares personal insights and challenges faced during testing, such as isolating unit tests and maintaining test data integrity, and hints at potential future enhancements using Flask-RESTful for improved API development.
