ArgumentCapture
inscalaの使用に問題がありDouble
ます。私はDouble
嘲笑された特性への議論を捕らえようとしています。をキャプチャしようとすると、同じ構文が正常に機能しますInt
。
テストの例を次に示します。
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
}
}
次の例外が発生します。
java.lang.Integer cannot be cast to java.lang.Double
java.lang.ClassCastException: java.lang.Integer cannot be cast to java.lang.Double
