Towards Continuous Performance Regression Testing
JfrUnit is an extension for JUnit 5 which integrates Flight Recorder into unit tests. It makes it straightforward to initiate a JFR recording for a given set of event types, execute some test routine, and then assert the JFR events which should have been produced. Stay tuned for next parts in this series, where we’ll explore how to trace the SQL statements executed by an application using the JMC Agent and assert these query events using JfrUnit.
The Java Flight Recorder (JFR) is an invaluable tool for gaining deep insights into the performance characteristics of Java applications.
In this blog post, we’re going to explore how custom, application-specific JFR events can be used to monitor a REST API, allowing to track request counts, identify long-running requests, and more.
