Mock Server
A mock server is a tool that simulates the behavior of a real API or service by returning predefined responses to requests, allowing developers to test and develop applications without relying on external dependencies. It is commonly used in software development to isolate components, test edge cases, and simulate various scenarios such as errors, delays, or specific data states. Mock servers can be configured to handle HTTP/HTTPS requests with custom routes, headers, and payloads, making them essential for integration testing, frontend development, and continuous integration pipelines.
Developers should use a mock server when building or testing applications that depend on external APIs or services that are unavailable, unstable, or costly to access during development. It is particularly useful for frontend developers who need to work on UI components before backend APIs are ready, enabling parallel development and reducing bottlenecks. Additionally, mock servers facilitate automated testing by providing consistent, controlled responses, helping to catch integration issues early and improve software reliability.
