Espresso Tests fail on Android 11

[kuuuurt]

Description

I have integration tests running from API 21 to API 29. I've been trying to update our app to target API 30 but the tests are flaky just on API 30.

Steps to Reproduce

1. I have a simple case where I tap on a button that should popup a dialog

btnDialog.setOnClickListener {
    MaterialAlertDialogBuilder(this).apply {
        setTitle("Test Dialog")
        setMessage("This should work on API 30")
        setPositiveButton(android.R.string.ok, null)
        create()
    }.show()
}  

2. Then I try to test it via:

// Given - fragment is launched
launchFragmentInContainer(...)

// When - the button is clicked
onView(withId(R.id.btn_dialog)).perform(click())

// Then - dialog with message should be shown
onView(withText("Test Dialog")).check(matches(isDisplayed()))
onView(withText("This should work on API 30")).check(matches(isDisplayed()))

• I also tried using RootMatchers.isDialog() but the same behavior.

Expected Results

This works perfectly from API 21 to API 29. It should also work in API 30. I also turned off all the compatibility changes just to check and it still is happening.

Actual Results

AndroidX Test and Android OS Versions

AndroidX Test: 1.3.0 Espresso: 3.3.0 Android OS: Android 11 (API 30)

[luis-cortes]

This is still happening on the latest alpha release 1.3.1-alpha03

androidx.test:runner:1.3.1-alpha03
androidx.test:orchestrator:1.3.1-alpha03
androidx.test.espresso:espresso-core:3.4.0-alpha03

[meesec]

seeing the same issue, also launching a dialog on a fragment

[zeinab-abdelmawla]

it's happing with me also even in Api 29

[kuuuurt]

I'm using 1.4.0-alpha04 for androidx.test and 3.4.0-alpha04 for espresso and it seems to work well with mine now. I have to use inRoot(isDialog()) though so I had to do away with using barista

onView(allOf(withText(text)))
        .inRoot(isDialog())
        .check(matches(isDisplayed()))

[rekaszeru]

Still happening (Android 11 only!) with androidx.test 1.4.0 / espresso 3.4.0 / target API 30 / compile SDK 31.

[tyborg]

Workaround: put a Thread.sleep(2000) to the setup part of the test to provide enough time to restart the app between the test cases.

[MeghaJanardhana]

I was also facing issues with test cases related to Alerts and Dialog windows with Android 30 SDK. The exceptions I observed were java runtime exceptions and were related to no window focus on root view, no matching root found etc. I upgraded androidx.test and espresso to 1.4.0-alpha04 and 3.4.0-alpha04 respectively. And running the tests on Android 11.0 (API 30) devices.

To resolve the issue, I modified test cases to use idling resources in setup method and also included thread.sleep as necessary. I also had to change these settings in the device's developer options: a) Transition animation zoom -> Off b) Window Animation scale -> Off c) Animator duration scale -> Off

This link below provides details on these settings for espresso multi-window support. https://github.com/android/testing-samples/tree/main/ui/espresso/MultiWindowSample

This resolved the runtime exceptions in my case. I hope this helps others too!

[lalitarya04]

It worked for me , inRoot(isDialog())

onView(allOf(withText(text))) .inRoot(isDialog()) .check(matches(isDisplayed()))

[waliahimanshu]

Face the same issue asserting text view inside BottomSheetFragment. I was using Kaspresso/Kako framework and using it.inRoot { isDialog() } fixed the problem.

val titleTextView = KTextView {
        withId(R.id.TitleTextView)
    }
    }.also { it.inRoot { isDialog() } }

Note: Kako's KAlertDialog had this in init, for the same reason. https://github.com/KakaoCup/Kakao/blob/2bfeaa5c4e04fac95096dd0795a753151a99e618/kakao/src/main/kotlin/io/github/kakaocup/kakao/dialog/KAlertDialog.kt#L17-L37

Edit: after this change, the test still fails intermittently.

[devorbh]

It works fine for me when I use "it.inRoot { isDialog() } " only on customised alerts, but I still see issue with Android native alerts. Did any one manage to fix it for native alerts?

@kuuuurt We have tests that are running on API 31 that we're seeing almost the exact same stacktrace for and the behavior is not consistent. Many times the tests will run without issues but sometimes those errors will pop up with the same stacktrace. Because we're running on a CI server and the failures are not consistent, I've never actually witnessed the failure occur. I think we are seeing these when trying to test dialogs or dialog fragments.

The thing I'm having trouble understanding is if this error is thrown before our test code is even run. Usually if an Espresso test fails I'll see some indication that some of my test's steps were run from the stacktrace e.g. I'll see an espresso log for a button being clicked and then I'll see some sort of failure but the stacktrace at least includes some Espresso actions that I've coded. In this case I don't see the same thing happening.

When your tests fail with that stacktrace, are you able to determine if your: onView(withId(R.id.btn_dialog)).perform(click()) is even run?

What I have observed the button in the dialogue fragment is visible but the test fails to click it.

[hoda0013]

Ok. I looked deeper into my logcat for the error I'm seeing. In my test, we create a fragment using FragmentScenario, then once it's created, the first thing we attempt to do is call:

Espresso.closeSoftKeyboard()

I noticed in my logs that I get the following output after calling closeSoftKeyboard():

The Espresso implementation for closeSoftKeyboard() is:

public static void closeSoftKeyboard() { onView(isRoot()).perform(ViewActions.closeSoftKeyboard()); }

So I think the onView(isRoot()) part must be what's causing this issue. I have no idea why it is intermittent though.

i have solved such issue by my own solution in Ultron framework(you can check realisation there). You can find an answer here: https://github.com/open-tool/ultron/wiki/Avoiding-nontrivial-element-lookup-exceptions
