MockServer on Ubuntu 24.04

Overview

MockServer is an open source tool for mocking and virtualising the HTTP and HTTPS services your application depends on. You configure expectations, request matchers paired with mock responses, forwards or callbacks, through a control API, then point systems under test at MockServer so they receive deterministic mocked responses instead of calling real dependencies that may be slow, costly, rate limited or not yet built. It can also run as a forward or reverse proxy to record and replay real traffic, and it ships a live web dashboard for inspecting requests and the expectations that matched them. Teams use it to develop against unfinished APIs, to isolate integration and end to end tests from flaky third parties, and to reproduce hard to trigger error and latency conditions on demand.

Common uses

• Mock and virtualise HTTP and HTTPS service dependencies
• Isolate integration and end to end tests from flaky third parties
• Proxy, record and replay traffic and simulate error conditions
