我有一个带私有字段的简单类。

class EmployeeData {

    private var employeeAge: Int = 0
    
    fun getAge(): Int {
        return 1 + employeeAge
    }
}

我试图测试这个私人employeeAge与以下从官方文档

@Test
fun testPrivateAge() {

    val mock = spyk(EmployeeData())

    every {
        mock getProperty "employeeAge"
    } propertyType Int::class answers { fieldValue + 6 }
    every {
        mock setProperty "employeeAge" value any<Int>()
    } propertyType Int::class answers  { fieldValue += value }

    every { mock getProperty "employeeAge" } returns 33
    every { mock setProperty "employeeAge" value less(5) } just Runs

    assertEquals(10,mock.getAge())
}

我收到了来自MockK的例外

io.mockk.MockKException: Missing calls inside every { ... } block.

at io.mockk.impl.recording.states.StubbingState.checkMissingCalls(StubbingState.kt:14)
at io.mockk.impl.recording.states.StubbingState.recordingDone(StubbingState.kt:8)

官方文档建议对私有财产使用这种技术，但对我来说它不起作用，我使用的是MockK的最新版本，它是v1.10.0。
虽然对于私有方法来说，它的工作原理就像一个魅力。我能够在这个逻辑中测试私有方法。
