Library aimed to provide support to integrate Monix Task with different testing frameworks.
Available for Scala 2.12 and 2.13 and 3.
This project is ported from typelevel/cats-effect-testing, with the difference that this library provides support for Task instead of IO. So credits to their authors and maintainers🙏
Mainly with the purpose of supporting task-testing on monix series 3.x,
since once monix is compatible with cats effect 3.0 this project will most likely not be longer useful,
since then we will be able to use cats-effect-testing 1.x
which is implemented with Tagless Final, thus compatible with
either IO and Task.
Add the following dependency to your build.sbt:
"io.monix" %% "monix-testing-scalatest" % "0.3.0"It provides a set of implicit conversions to convert [[Task]] to [[Future]], so the user does not need to do it for every test.
import monix.eval.Task
import monix.execution.Scheduler
import monix.testing.scalatest.MonixTaskTest
import org.scalatest.funsuite.AsyncFunSuite
import org.scalatest.matchers.should.Matchers
class DummySpec extends AsyncFunSuite with MonixTaskTest with Matchers {
override implicit def scheduler: Scheduler = Scheduler.io("monix-task-support-spec")
test("AsyncTestSuite with Task support") {
for {
r1 <- Task(2)
r2 <- Task(r1 * 3)
} yield {
r1 shouldBe 2
r2 shouldBe 6
}
// no need for tranforming the [[Task]] to [[Future]] or to awaiting for its result.
}
test("AsyncTestSuite with Task and AssertingSyntax support") {
Task(2).flatMap(r1 => Task(r1 * 3)).asserting(_ shouldBe 6)
}
}Add the following dependency to your build.sbt:
"io.monix" %% "monix-testing-utest" % "0.3.0"It provides a wrapper conversions from [[Task]] to [[Future]].
import monix.eval.Task
import monix.execution.Scheduler
import monix.testing.utest.MonixTaskTest
import utest.{Tests, test}
import scala.concurrent.duration._
class DummySuite extends MonixTaskTest {
override implicit val scheduler: Scheduler = Scheduler.io("monix-task-test")
override val timeout = 1.second
val tests = Tests {
test("dummy test") {
Task(assert(true))
}
}
}Minitest is very similar to uTest, but being strongly typed:
Add the following dependency to your build.sbt:
"io.monix" %% "monix-testing-utest" % "0.3.0" import monix.eval.Task
import monix.execution.Scheduler
import monix.testing.minitest.MonixTaskTest
import scala.concurrent.duration._
object DummySuite extends MonixTaskTest {
override val timeout = 1.second // Default timeout is 10 seconds
override protected implicit val scheduler: Scheduler = Scheduler.global
test("dummy test") {
Task(assert(true))
}
}Finally, specs2 can directly be used from "com.codecommit" %% "cats-effect-testing-specs2" % "0.5.4", the latest release
that is compatible with monix 3.x.
import monix.eval.Task
import monix.execution.Scheduler
import cats.effect.testing.specs2.CatsEffect
import org.specs2.mutable.Specification
import scala.concurrent.duration._
implicit val scheduler: Scheduler = Scheduler.global
class DummySpec extends Specification with CatsEffect {
"dummy test" should {
"be successful" in Task {
true must beTrue
}
}
}
