Mam problem z używaniemArgumentCapture dlaDouble w scali. Próbuję uchwycićDouble argument do wyśmiewanej cechy. Ta sama składnia działa dobrze podczas próby przechwyceniaInt.

Oto przykładowy test:

import org.scalatest.FunSuite
import org.scalatest.mock.MockitoSugar
import org.mockito.Mockito._
import org.mockito.ArgumentCaptor

trait MockedTrait {
    def mockedDoubleMethod(double: Double)
    def mockedIntegerMethod(integer: Int)
}

class ClassUnderTest(myTrait: MockedTrait) {
    def methodUnderTest {
        myTrait.mockedIntegerMethod(3)
        myTrait.mockedDoubleMethod(5.0)
    }
}

class MyTest extends FunSuite with MockitoSugar {

    test("A basic test") {
        val myTrait = mock[MockedTrait]

        val classUnderTest = new ClassUnderTest(myTrait)
        classUnderTest.methodUnderTest

        val capturedInteger = ArgumentCaptor.forClass(classOf[Int])
        verify(myTrait).mockedIntegerMethod(capturedInteger.capture)

        val capturedDouble = ArgumentCaptor.forClass(classOf[Double])
        verify(myTrait).mockedDoubleMethod(capturedDouble.capture) // Throws ClassCastException
    }

}

Mam następujący wyjątek:

java.lang.Integer cannot be cast to java.lang.Double
java.lang.ClassCastException: java.lang.Integer cannot be cast to java.lang.Double

Jakieś sugestie?
