Logging and Testing with Helidon
summary
Helidon provides a unified MDC API that adds MDC support to java.util.logging and propagates MDC values across threads so async JAX‑RS client callbacks still show the same request id, and the demo proves it works. Testing uses a Helidon Test annotation that auto‑creates server and WebTarget on a random port, supports class or per‑test configuration overrides, injectable config properties, and adding single test CDI beans with optional per‑test reset to recreate server between tests.
