How do you mock scala call-by name in Mockito

Question

Im trying to mock scala call-by name method in mockito. But running into this error.

This exception may occur if matchers are combined with raw value

Answer 1

You can use https://github.com/mockito/mockito-scala

import com.example.{CacheHelper, Command}
import org.mockito.ArgumentMatchersSugar._
import org.mockito.IdiomaticMockito
import org.scalatest.{Matchers, _}

  class ExampleSpec extends FlatSpec with Matchers with BeforeAndAfter with IdiomaticMockito {

    "it" should "call commands execute" in {
      val cacheHelper: CacheHelper = new CacheHelper
      val commandMock: Command = mock[Command]
      val spyCacheHelper = spy(cacheHelper)

      spyCacheHelper.isCircuitBreakerEnabled shouldReturn true
      spyCacheHelper.createCommand(any[String], any[Long]) shouldReturn commandMock 

      val result: Long = spyCacheHelper.getOrElse("key")(1L)
      println("result = " + result)
      verify(commandMock).execute()

    }

  }

Should be able to do it with scalamock: How to mock a call-by-name argument (like getOrElse) using ScalaMock?
