Question

在测试中，我想模拟一个没有构造函数的类，而该构造函数为此我找到了最终的类；

MessageAnimation

class MessageAnimation {

    fun fadeIn(layout: View, delay: Int) {
        val showMessage = AlphaAnimation(0.0f, 1.0f)
        showMessage.fillAfter = true
        showMessage.startOffset = delay.toLong()
        showMessage.duration = 1500
        layout.startAnimation(showMessage)
    }

    fun fadeOut(view: View, delay: Int) {
        val showMessage = AlphaAnimation(1.0f, 0.0f)
        showMessage.fillAfter = true
        showMessage.startOffset = delay.toLong()
        showMessage.duration = 1500
        showMessage.start()
        view.startAnimation(showMessage)
    }

    fun moveUp(layout: LinearLayout, delay: Int) {
        val objectAnimator = ObjectAnimator.ofFloat(layout, "translationY", (-125.0).toFloat())
        objectAnimator.startDelay = delay.toLong()
        objectAnimator.duration = 1500
        objectAnimator.start()
    }

    fun moveDown(layout: LinearLayout, delay: Int) {
        val objectAnimator = ObjectAnimator.ofFloat(layout, "translationY", (-125.0).toFloat())
        objectAnimator.startDelay = delay.toLong()
        objectAnimator.duration = 1500
        objectAnimator.start()
    }

    fun moveOutOfScreen(layout: LinearLayout, delay: Int) {
        val objectAnimator = ObjectAnimator.ofFloat(layout, "translationY", (-300.0).toFloat())
        objectAnimator.startDelay = delay.toLong()
        objectAnimator.duration = 1500
        objectAnimator.start()
    }
}

在测试中，我想模拟此类，因此发现可以为此使用PowerMock。我定义了该类应该使用它，并且还通过定义了此函数来准备测试以使用它。但是，在模拟之前不准备此类，我仍然遇到错误。

有人知道这是为什么吗？

ActivityTest.kt

@RunWith(PowerMockRunner::class)
@PrepareForTest(MessageAnimation::class)
class ActivityTest {

    private val messageAnimationMock = mockStatic(MessageAnimation::class.java)
    // other code
}

错误：

org.powermock.api.mockito.ClassNotPreparedException: 

[Ljava.lang.Object;@1a6d8329
The class robot.fsrt.robotguest.common.animation.MessageAnimation not prepared for test.

定义了PrepareForTest时的Powermock ClassNotPreparedException
