Android：Espresso：无法检查未显示主页按钮

Question

Android Studio 3.2

要检查的是显示主页按钮，我使用下一个测试（解决方法）

 @Test
    fun toolbar_homeButton_isDisplayed() {
        onView(withContentDescription(R.string.abc_action_bar_up_description))
                .check(matches(isDisplayed()))
    }

但是如何检查主页按钮不显示。

此测试失败：

@Test
    fun toolbar_homeButton_isNotDisplayed() {
        onView(withContentDescription(R.string.abc_action_bar_up_description))
                .check(matches(not(isDisplayed())))
    }

错误：

androidx.test.espresso.NoMatchingViewException: No views in hierarchy found matching: with content description from resource id: <2131623937>[abc_action_bar_up_description] value: Navigate up
