How to check that popup notification is NOT displayed. Espresso

I have popup notification. My first test checks if that notification is displayed and it passes succesfully. I use next method for this test: 

fun viewInNotificationPopupIsDisplayed(viewMatcher: Matcher<View>) {
    onView(viewMatcher)
        .inRoot(RootMatchers.isPlatformPopup())
        .check(ViewAssertions.matches(isDisplayed()))
}

I have a problem with second test case where i have to check that my popup notification has already gone (means it's not displayed anymore). So i'm trying to use next method:

    fun viewInNotificationPopupIsNotDisplayed(viewMatcher: Matcher<View>) {
        Espresso.onView(viewMatcher)
            .inRoot(RootMatchers.isPlatformPopup())
            .check(matches(not(isDisplayed())))
          //.check(ViewAssertions.doesNotExist())  // doesn't work as well
    }

I get next exception:

android.support.test.espresso.NoMatchingRootException: 
Matcher 'with decor view of type PopupWindow$PopupViewContainer' 
did not match any of the following roots: 
[Root{application-window-token=android.view.ViewRootImpl$W@bb8371e,
 window-token=android.view.ViewRootImpl$W@bb8371e, has-window-focus=true,

Please, can anybody help with this?

Seems that such simple check is impossible with espresso if you have a PopupWindow because of the way the NoMatchingRootException is thrown

You may just catch the exception and complete the test but that's not a good option since throwing and catching NoMatchingRootException consumes a lot of time in a comparison with the default test case. Seems that Espresso is waiting for the Root for a while

For this case is suggest just to give up with espresso here and use UiAutomator for this assertion

val device: UiDevice
   get() = UiDevice.getInstance(InstrumentationRegistry.getInstrumentation())

fun assertPopupIsNotDisplayed() {
    device.waitForIdle()
    assertFalse(device.hasObject(By.text(yourText))))
}

fun assertPopupIsDisplayed() {
    device.waitForIdle()
    assertTrue(device.hasObject(By.text(yourText))))
}
