Generation of arbitrary case classes / ADTs instances with scalaprops and shapeless ported from alexarchambault/scalacheck-shapeless.
Add to your build.sbt
libraryDependencies += "com.github.scalaprops" %% "scalaprops-shapeless" % "0.6.0"Import the content of scalaprops.ScalapropsShapeless close to where you want
scalaprops.Gen type classes to be automatically available for case classes / sealed hierarchies,
import scalaprops.ScalapropsShapeless._
// If you defined:
// case class Foo(i: Int, s: String, blah: Boolean)
// case class Bar(foo: Foo, other: String)
// sealed trait Base
// case class BaseIntString(i: Int, s: String) extends Base
// case class BaseDoubleBoolean(d: Double, b: Boolean) extends Base
// then you can now do
Gen[Foo]
Gen[Bar]
Gen[Base]and in particular, while writing property-based tests,
val `some property about Foo` = Property.forAll {
(foo: Foo) =>
// Ensure foo has the required property
}without having to define yourself a scalaprops.Gen for Foo.
