maximock is a WireMock-based alternative to Postman, published as a Maven package under WeDontTrack. It brings API mocking into JVM workflows without an external app, account, or any tracking.

Why

Mocking and exercising APIs usually means reaching for a heavyweight desktop tool. maximock keeps it in code and in your build, where it’s versioned, reviewable, and runs in CI like any other dependency.

Architecture

maximock wraps WireMock so stubs are declared in test code instead of a separate GUI. At runtime it spins up an embedded HTTP server that answers from a stub registry — so the code under test calls it exactly like a real API.

API mocking in your build: tests declare stubs, maximock serves them over a local HTTP endpoint

Technical explanation

  • Stubs as code. Request matchers and canned responses are defined in the test, so they live in version control, get code-reviewed, and diff like anything else.
  • Embedded HTTP server. maximock starts a local endpoint backed by WireMock; the system under test points at it and behaves as if it were talking to the real service.
  • CI-native. Because it’s just a Maven dependency, there’s no separate app to install or account to manage — it runs the same on a laptop and in a pipeline, with no tracking.
