ScalaCheck is a library written in Scala and used for automated property-based testing of Scala or Java programs. ScalaCheck was originally inspired by the Haskell library QuickCheck, but has also ventured into its own.
ScalaCheck has no external dependencies other than the Scala runtime, and works great with sbt, the Scala build tool. It is also fully integrated in the test frameworks ScalaTest, specs2, and LambdaTest. You can of course also use ScalaCheck completely standalone, with its built-in test runner.
