Symbol 'type <none>.scalacheck.Shrink' is missing from the classpath - scala

Question

I have the following ScalaCheck unit test using Mockito:
import org.scalatest.mockito.MockitoSugar
import org.mockito.Mockito.when
import org.scalatest.prop.PropertyChecks
import org.mockito.Mockito.verify
class PlayerTest extends org.scalatest.FunSuite with MockitoSugar with PropertyChecks {
test("doesn't accept anything but M") {
val mockIOHandler = mock[IOHandler]
val name = "me"
val player = new Player(name)
when(mockIOHandler.nextLine).thenReturn("m")
val apiUser = new Player("player1")
apiUser.chooseHand(mockIOHandler)
verify(mockIOHandler).write("some value")
}
}
In my build.sbt I have the following dependencies:
scalaVersion := "2.12.2"
libraryDependencies += "org.scalactic" %% "scalactic" % "3.0.1"
libraryDependencies += "org.scalatest" %% "scalatest" % "3.0.1" % "test"
// https://mvnrepository.com/artifact/org.mockito/mockito-core
libraryDependencies += "org.mockito" % "mockito-core" % "1.8.5"
For it, I am getting this error:
Error:(12, 41) Symbol 'type <none>.scalacheck.Shrink' is missing from the classpath.
This symbol is required by 'value org.scalatest.prop.GeneratorDrivenPropertyChecks.shrA'.
Make sure that type Shrink is in your classpath and check for conflicting dependencies with `-Ylog-classpath`.
A full rebuild may help if 'GeneratorDrivenPropertyChecks.class' was compiled against an incompatible version of <none>.scalacheck.
test("doesn't accept anything but M") {
Any idea what could be wrong?

Answer 1

Adding scalacheck did the trick for me
lazy val scalaTest = "org.scalatest" %% "scalatest" % "3.0.+"
lazy val scalaCheck = "org.scalacheck" %% "scalacheck" % "1.13.+"
