RX Java 测试中的单元测试无法理解的结果

有这样一个测试。

@Test
fun needShowOnboarding() {
    val cards = listOf(
        mockCard(cardUcid = "1", pinSet = false),
        mockCard(cardUcid = "2", pinSet = true),
        mockCard(cardUcid = "3", pinSet = true)
    )
    val account = mockBankAccount(cards)

    val testObserver = pinSetCardCheker.getOnboardingShowingMode(listOf(account)).test()

    with(testObserver) {
        assertNoErrors()
        assertValueCount(1)
        assertResult(PinSetOnboardingShowingMode.Single("1"))
    }
}

其实这样的对象应该是返回PinSetOnboardingShowingMode.Single("1")了才返回的，只是测试不断地crash，报错：

java.lang.AssertionError: Values at position 0 differ; expected: ...PinSetOnboardingShowingMode$Single@5ec77191 (class: Single) but was: ...PinSetOnboardingShowingMode$Single@4642b71d (class: Single) (latch = 0, values = 1, errors = 0, completions = 1)
Expected :...PinSetOnboardingShowingMode$Single@5ec77191 (class: Single) 
Actual   :...PinSetOnboardingShowingMode$Single@4642b71d (class: Single) (latch = 0, values = 1, errors = 0, completions = 1)

如果我们打开比较对象之间的差异，我们会看到以下内容：

• ...PinSetOnboardingShowingMode$Single@5ec77191 (class: Single)
• ...PinSetOnboardingShowingMode$Single@4642b71d (class: Single) (latch = 0, values = 1, errors = 0, completions = 1)

这对我来说仍然是一个谜，它在结果对象中的位置：

“（闩锁= 0，值= 1，错误= 0，完成= 1）”。

这是PinSetOnboardingShowingMode类本身：

sealed class PinSetOnboardingShowingMode {
    object None : PinSetOnboardingShowingMode()
    class Single(val cardUcid: String) : PinSetOnboardingShowingMode()
    class List(val cardUcidsWithoutPin: ArrayList<String>) : PinSetOnboardingShowingMode()
}

只要getOnboardingShowingMode返回相同的方法 ( ) boolean，PinSetOnboardingShowingMode测试就成功了。
