🤞Fingers crossed--just submitted a couple of sessions for @DevoxxUK. Two for the Data track on real-time data pipelines and data contracts, and a lightning one on performance regression testing with #JfrUnit. CfP closes soon, so get yours in too: 👉 https://t.co/0zhjuV0eKB

@FranckPachot Sounds like #JfrUnit (https://t.co/IHBBBsn4Ks) may fit the bill here? Asserting expected DB I/O or executed SQL statements in automated tests is one of its use cases.

👇How cool is that?! @piotrprz is using #JfrUnit in his tests to make sure there are no pinned virtual threads (i.e. a #Loom virtual thread cannot be unmounted from its carrier thread). A really neat usage of JfrUnit 👏.

How to misuse Virtual Threads in #Java 19? Well, we may pin them. Or not. https://t.co/TOyKuZm9T3

"Continuous Performance Regression Testing with JfrUnit" Timestamped outline for my #JfrUnit talk at @JChampionsConf earlier this year. Kudos to @MeneDev for creating this -- very handy for folks curious to check out specific parts of that recording 🙏. https://t.co/dZ0yyVtDDK

Know your #SQL is one of the core messages, author @gunnarmorling addresses in his #javaadvent21 article "Keep Your SQL in Check With Flight Recorder, JMC Agent and #JFRUnit". Definitely a good read that you can still find here: https://t.co/u39Wi4D1LV #java

Hey there @tomsontom 👋, any plans for adding Java 18 and 19 to https://t.co/M5o22KLj7x? Would love to have those handy JSON definitions for the latest event types for #JfrUnit :) #JDKFlightRecorder

Wouldn't it be awesome if @Hibernate exposed flight record events so you did'nt have to fiddle with the jmc-agent when using #jfrunit to verify your database calls. #jfr https://t.co/Byz9AWfFeM

🎉 Woot, a new example for #JfrUnit is up: capturing SQL statements emitted by @JavaOOQ from a Spring Boot app with JDK Flight Recorder, using #JMC Agent. Thanks a lot to Jordie B. for this amazing contribution 🙏! #OSSFTW https://t.co/Ygd866oj0i

A very useful API improvement merged to #JfrUnit: type-safe access to all the JFR event types and their attributes in assertions (generated from defs at https://t.co/iKIl0xIMuF)! Big shout-out to Federico Mariani (@croway_) for this huge piece of work 🙏. https://t.co/IHBBBsn4Ks
