Dummy API for Testing: How to Use It vs Mocking

A dummy API for testing is a simple, static representation of an API that simulates basic interactions or serves as a placeholder while the real API is under development. It returns fixed, consistent responses to mimic the structure and format of the real API. Dummy APIs are useful for testing connections, allowing front-end developers to continue building and testing interfaces without waiting for the backend to be ready. They also enable independent workflows between frontend and backend teams, speeding up development. Key features of a good dummy API include predefined responses, simple setup and use, realistic data structure, support for basic HTTP methods, and availability across environments. Creating a dummy API involves choosing a tool or framework, defining endpoints, creating dummy data, setting up the API, testing it, and iterating and expanding as needed. Best practices for using dummy APIs include matching real API behavior, simulating realistic scenarios, using meaningful test data, documenting the API, updating it as needed, and distinguishing between dummy and mock APIs. While both are used for testing, a tool like Blackbird offers the best of both worlds by providing code for static responses and allowing for dynamic response testing within the same platform.
