Generated code that ships real tests
“Tested” is easy to claim and easy to fake with empty happy-path tests. Here it means a four-layer pyramid, success and error paths, and coverage you can inspect, measured with JaCoCo, not asserted in a slide.
The four-layer test pyramid
Unit (every class in isolation, collaborators mocked), integration (persistence adapters against real PostgreSQL/MongoDB/Redis via Testcontainers), component (the whole service driven through its HTTP boundary), and end-to-end (a full user journey with every collaborator real). Each is its own Maven profile.
Coverage, measured not claimed
Methods, lines and branches, measured with JaCoCo. Every path executed and asserted, not just run. Error paths too: 400, 401, 404, 415, not only the 200. There’s deliberately no consumer-contract layer, because the OpenAPI/Swagger spec is the contract and the component layer verifies it.
Inspect it yourself
Every demo exposes the real artifacts behind the number: live Swagger, the Allure dashboard, JaCoCo coverage and the raw test files. The coverage stops being a claim and becomes something you can open.
