HTTP Stubbing

HTTP stubbing is a technique used in software testing and development to simulate HTTP server responses by intercepting and modifying network requests. It allows developers to create mock endpoints that return predefined data, enabling isolated testing of client-side code without relying on real backend services. This is commonly implemented using libraries or tools that act as proxies to capture and stub HTTP traffic.

Also known as: HTTP Mocking, Network Stubbing, API Stubbing, HTTP Interception, Request Stubbing

🧊Why learn HTTP Stubbing?

Developers should use HTTP stubbing when testing frontend applications, APIs, or microservices in isolation to ensure reliability and speed. It is particularly useful for simulating error conditions, slow responses, or specific data scenarios that are hard to reproduce with live servers, making it essential for unit testing, integration testing, and development in environments with unstable or unavailable backend services.
