Specs2, from starters to dessert and... a look in the kitchen.
summary
Covers concrete features and tradeoffs: data tables using | and ! operators that compile with aligned cells, command-line control of ScalaCheck parameters and per-example overrides (min tests, generators), custom matters that produce clearer failure messages, concurrency by default with a sequential/isolated option, runtime-created specs implemented as a monadic flatMap on a stream of fragments, HTML docs that embed executable code snippets, and implementation notes about a macro using -Yrangepos plus a tiny streaming/fold reporter framework and the maintenance cost of reimplementing FP primitives.
