Haha! Credits go to Alex Soto (x.com/alexsotob) who created the issue github.com/quarkiverse/... and commented: "This would be similar to a standard Quarkus test with Rest Assured, but for MCP."

It would be great to have a testing module that automatically starts the MCP Server (stdin or streaming) and injects an MCP Client instance into the test, allowing you to write tests against it. Th...

💡 03 for #quarkus extension devs: if you build a native image and wonder what's registered by Quarkus for reflection, take a look at: target/quarkus-app/quarkus/generated-bytecode.jar!META-INF/native-image/reflect-config.json 👀. That's all, thanks for your attention.

Martin Kouba @martunek.bsky.social · May 30

💡 02 for #quarkus devs: with io.quarkus.runtime.LaunchMode.current() you can detect the current launch profile. TEST is activated when running tests. DEVELOPMENT is activated in development mode (i.e. quarkus:dev). And NORMAL stands for normal production. That's all, thanks for your attention.

Martin Kouba @martunek.bsky.social · May 29

01 for Quarkus devs: with io.quarkus.runtime.ImageMode#current() you can detect the current execution mode. You get JVM if app is running in a standard JVM. NATIVE_BUILD if a native image is being built. And NATIVE_RUN if a native image is running. That's all, thanks for your attention.

The @quarkus.io team is amazing. They've developed an MCP Server extension. It took me half a day to write a not-so-trivial MCP Server and expose it to a @langchain4j.dev client. Really good stuff #Bravo

Believe it or not, the next release of Quarkus will be the 365th release since Quarkus became a thing, 6 years ago. It will be one year of release days! I released the large majority of them but this will change a bit with @janmartiska.bsky.social taking the responsibility for some LTS streams!

For Quarkus, we often ask for simple reproducers when users report an issue. It might seem like wasted time for you but it's not. It happens often that the information is not enough to reproduce the issue and trying to guess how we can trigger the error is a massive waste of time on our time. 🧵
