Mock your APIs for fast, robust and comprehensive testing
WireMock is a simulator for HTTP-based APIs. Some might consider it a service virtualization tool or a mock server.
It enables you to stay productive when an API you depend on doesn't exist or isn't complete. It supports testing of edge cases and failure modes that the real API won't reliably produce. And because it's fast it can reduce your build time from hours down to minutes.
Run WireMock from within your Java application, JUnit test, Servlet container or as a standalone process.
