Expecty 0.17.1 is released. Expecty brings power assert (or power assertion) to Scala. It was originally implemented by Peter Niederwieser who implemented the original power assertion Spock in Groovy. It had gone dormant for a while, and I forked it in 2018 , and started publishing it against modern build matrix like Scala 2.12, 2.13, 3.x, JVM, JS, and Native.
