> Spock framework above all, it is written in groovy You're the one who's telling an "outright lie" (as you put it). I just downloaded and unzipped Spock from Github, and looked through its directory structure. Virtually all of it is written in Java, not Apache Groovy. There's only a few little files written in Groovy. Perhaps you're confusing its source language with the language users of Spock write their test scripts in. In real life, Groovy is used for the JVM in the same way Bash is used for Linux, like writing glue code and build files. The statically typed stuff added in Groovy 2.x isn't used much at all, and virtually no-one would use Groovy to build actual systems. All software I know of that provides Groovy to users, like Grails, Gradle, and Spock, is itself written in Java.
