Nyaya is a Scala/Scala.JS library to:
- Test properties using random data.
- Prove properties with (reasonably-sized) finite domains.
- Assert properties in real data.
- Generate random data.
- Ensure uniqueness in random data.
- Fast. Probably the fastest Scala random data gen / prop tester. (Benchmarks coming soon…)
- Has a nice, fluent API for generating random data. (examples)
scala> import nyaya.gen._ import nyaya.gen._ scala> val g = Gen.int mapTo Gen.boolean.option g: nyaya.gen.Gen[Map[Int,Option[Boolean]]] = Gen(<function1>) scala> g.samples().take(1).foreach(println) Map(609117252 -> None, -339 -> Some(true), 1684851879 -> Some(false), 78379 -> None)
// Property expression, evaluation, assertion. libraryDependencies += "com.github.japgolly.nyaya" %%% "nyaya-prop" % "0.8.1" // Random data generation. libraryDependencies += "com.github.japgolly.nyaya" %%% "nyaya-gen" % "0.8.1" // Property testing with random data. // Property proving. libraryDependencies += "com.github.japgolly.nyaya" %%% "nyaya-test" % "0.8.1" % "test"
