Introducing JfrUnit 1.0.0.Alpha1

Read Original

JfrUnit is a new JUnit extension that allows developers to assert JDK Flight Recorder (JFR) events in their unit tests. It enables testing of custom JFR event emission, identifying performance regressions (e.g., in garbage collection or memory allocation), and whitebox testing with JMC Agent. The article covers getting started, Maven dependency setup, example usage with Quarkus, and its place within the ModiTect family of Java infrastructure projects.
