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" % "0.9.0" % Test
Mill
object test extends Tests {
def ivyDeps = Agg(
ivy"org.typelevel::weaver-discipline:0.9.0"
)
}
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)
}
