property based testing library for Scala
- real
scala.FunctionNgenerators usingCogen(akaCoArbitraryin QuickCheck). scalaprops can generate not only constant Functions - flexible parameter settings for each test(ScalaCheck doesn't have this feature)
- timeout as soon as possible
- flexible law checking likediscipline
- discipline uses only
Stringfor test id. but scalaprops can use other thanString - scalaz integration
- laws for scalaz typeclasses
GenandCogeninstances of scalaz datatypes- immutable random number generator
- scalaprops does not use
scala.util.Randombecausescala.util.Randomis mutable - default implementation isMersenne Twister(JVM, scala-native) orTiny Mersenne Twister(Scala.js)
- Scala.jssupport
- scala-nativesupport. seehttps://github /scalaprops/scalaprops-native-example
- deterministic testing
please use sbt plugin because there are some convenient features.
setup without sbt plugin

Scalaprops emitting which seed it started with during a failing test, and providing an interface--seed=<value>for re-running the failing test with the same seed.
