Discipline integration

Weaver comes with basic Discipline integration, allowing property-based law testing.

Installation

You'll need to install an additional dependency in order to use Discipline with Weaver.

SBT

libraryDependencies +=  "org.typelevel" %% "weaver-discipline" % "0.10.1" % Test

Mill

object test extends Tests {
  def ivyDeps = Agg(
    ivy"org.typelevel::weaver-discipline:0.10.1"
  )
}

Usage

Add the weaver.discipline.Discipline mixin to a FunSuite to use Discipline within your test suite.

import weaver._
import weaver.discipline._
import cats.kernel.laws.discipline.EqTests

object DisciplineTests extends FunSuite with Discipline {
  checkAll("Int", EqTests[Int].eqv)
  checkAll("Boolean", EqTests[Boolean].eqv)
}
