About
WireMock is an open source API mocking and simulation tool that allows developers to stub HTTP responses, simulate faults, and test applications independently of real API dependencies. It supports dynamic response templating, record and playback, and seamless integration with testing frameworks like JUnit. An enterprise cloud offering, WireMock Cloud, extends the core tool with collaboration features, AI assistance, and CI/CD integration.
Problem
Development and testing is blocked or unreliable when APIs you depend on are unstable, unavailable, or don't yet exist.
For
software developers and QA engineers building and testing applications with external API dependencies
How it works
WireMock intercepts HTTP requests and returns configurable stub responses, supporting URL pattern matching, dynamic templating, fault simulation, and record/playback of real service interactions.
