The easiest way to try Kotlin isn’t rewriting your Java app – it’s writing tests. Drop a Kotlin test next to your JUnit/Mockito setup and you’ll immediately see the difference: less noise, more clarity, same JVM. ➡️ Learn more in the Kotlin Adoption Guide: jb.gg/kotlin-guide

If you're not sure why, or how to fix it without breaking error isolation, I'll be covering more in-depth scenarios at ktconf.be in a workshop. If your team has lots of hard-to-reproduce bugs, this workshop might be for you ❤️
