我在使用 scala 时遇到ArgumentCapture问题Double。我试图捕捉Double一个模拟特征的论点。尝试捕获Int.

这是一个示例测试:

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
    }

}

我得到以下异常:

java.lang.Integer cannot be cast to java.lang.Double
java.lang.ClassCastException: java.lang.Integer cannot be cast to java.lang.Double
    at scala.runtime.BoxesRunTime.unboxToDouble(Unknown Source)
    at MyTest$$anonfun$1.apply$mcV$sp(MyTest.scala:30)
    at MyTest$$anonfun$1.apply(MyTest.scala:20)
    at MyTest$$anonfun$1.apply(MyTest.scala:20)
    at org.scalatest.FunSuite$$anon$1.apply(FunSuite.scala:1265)
    at org.scalatest.Suite$class.withFixture(Suite.scala:1968)
    at MyTest.withFixture(MyTest.scala:18)

有什么建议么?

我有类似的问题。我相信这应该可以解决它:

val capturedDouble = ArgumentCaptor.forClass(classOf[java.lang.Double])
