Run all tests without the #RunWith(classOf[JUnitRunner]) dance? - scala

Question

Is there any way to set up IntelliJ's JUnit "Run All Tests" command to automatically pick up Scala Specs2? i.e. removing the boilerplate annotation in this snippet:
#RunWith(classOf[JUnitRunner])
class MySpec extends Specification
It's very irritating to have to remember to add this.
I've seen SpecificationWithJUnit but that is also a bit of a hack (and is incompatible with TestKit). I'm looking for a maven/sbt/intelliJ side solution.

Answer 1

With Intellij, you shouldn't need the annotation to execute your specifications, because it has its own specs2 runner. I'm using IntelliJ 123.100 with a recent version of the Scala plugin (82 I think) and things work ok (except for this issue).

Answer 2

Use #RunWith(classOf[JUnitPlatform]) instead JUnitRunner
Maybe this could help you:
import org.junit.jupiter.api.{DisplayName, Test}
import org.junit.platform.runner.JUnitPlatform
import org.junit.runner.RunWith
import org.scalatest.{BeforeAndAfterAll, Matchers}
import org.scalatest.junit.JUnitSuite
#RunWith(classOf[JUnitPlatform])
class Junit5Test extends JUnitSuite with Matchers with BeforeAndAfterAll {
override def beforeAll: Unit = { println(">>> beforeAll <<< ") }
#Test
#DisplayName("Example with JUnitSuite")
#throws(classOf[RuntimeException])
def throwsExceptionWhenCalled() {
println("Запуск теста...")
assertThrows[RuntimeException] { throw new RuntimeException }
}
}
And build.sbt file:
val junitJupiter = "5.2.0"
val junitPlatform = "1.2.0"
libraryDependencies ++= Seq(
"junit" % "junit" % "4.12" % Test,
"org.junit.jupiter" % "junit-jupiter-api" % junitJupiter % Test,
"org.junit.jupiter" % "junit-jupiter-engine" % junitJupiter % Test,
"org.junit.jupiter" % "junit-jupiter-params" % junitJupiter % Test,
"org.junit.platform" % "junit-platform-launcher" % junitPlatform % Test,
"org.junit.platform" % "junit-platform-engine" % junitPlatform % Test,
"org.junit.platform" % "junit-platform-runner" % junitPlatform % Test,
)
