Discipline integration · Weaver Test

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 +=  "com.disneystreaming" %% "weaver-discipline" % "0.6.7" % Test

Mill

object test extends Tests {
  def ivyDeps = Agg(
    ivy"com.disneystreaming::weaver-discipline:0.6.7"
  )
}

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)
}

DisciplineTests + Int: eq.antisymmetry eq 60ms + Int: eq.reflexivity eq 9ms + Int: eq.symmetry eq 8ms + Int: eq.transitivity eq 7ms + Boolean: eq.antisymmetry eq 8ms + Boolean: eq.reflexivity eq 2ms + Boolean: eq.symmetry eq 3ms + Boolean: eq.transitivity eq 1ms
