Value of ElapsedTimeIdlingResource?

Been thinking a lot about this recently because I've seen it in a few projects and I'm struggling to see what it offers over a simple Thread.sleep. The only context I can find is this blog post, which simply states "We could use SystemClock.sleep(60000), but that blocks the testing thread.". This is a strange justification since IdlingResources cause onView and onIdle to block the testing thread and this is wanted and expected behaviour for test code (tests are always run synchronously).
As far as I can tell using this IdlingResource is identical to using a sleep from a thread execution standpoint, but the code is more verbose and harder to understand. This seems to me like a misuse of IdlingResource and a testing anti-pattern, and it seems to be used in many codebases where a sleep would be simpler. Please let me know if there's some other execution property that makes this implementation advantageous.
Thanks.

Way to test multiple device test cases

Hi Chiuki, I was wondering is there a way to test, in espresso, scenarios like chat application, where you need two devices, one from you send message and on the other you receive the message and also assert for received push notifications? Seeking Help

ElapsedTimeIdlingResource no longer works with the new Espresso IdlingRegistry.

The former Espresso.registerIdlingResources() method has been deprecated in favor of using the new IdlingRegistry via getInstance().register(). However, after upgrading, my test no longer work using the ElapsedTimeIdlingResource.

        mElapsedTimeIdlingResource = new ElapsedTimeIdlingResource(3);
        getInstance().register(mElapsedTimeIdlingResource);
       // Do Something
        getInstance().unregister(mElapsedTimeIdlingResource);

Rotate screen tests failed on Android P Preview

I am running the tests using emulator, and I can see a dialog showing after the roatation. Here is the screenshot and log.
I assume it's the dialog that causes the app to not able to match id? How can we solve this? Thanks.

okhttp:2.4.0

Is it possible to use the library with com.squareup.okhttp:okhttp:2.4.0?
There is a lot of legasy code that I don't whant to change to okhttp 3 for now.

Need a helper method to clear app data and then continue running test cases

Just like the rotate-screen method you have created can you help me in creating a method to clear user data(Which should work same as going to app info>>storage>>clear data)
I am trying to automate the Onboarding process and need to clear app data before each test run.
So far I have found ways to run adb commands to clear data but using that closes the app thus failing the tests.
I need to use the method in @before of the test suite so that before each test execution the data is cleared.

How to understand the default synchronization function of Espresso

Hello,I see the following content written on your blog

How to understand the default synchronization function of Espresso
for example ,I use Handler send a message to UI thread , is there a UI event in the current message queue?
And what is the default AsyncTask thread pool meaning(use the class of AsyncTask in your app)?
Looking forward to your answer @chiuki thanks

Feature request: Dialog by instanceOf not just tag.

Hello,
What do you think of a idling resource that you could use for all your espresso tests that checks
getFragmentManager().getFragments() and iterates through seeing if any of them are LoadingDialogFragment - rather than having to register and unregister before every time a spinner pops up, just register in before and unregister in after?

Since any spinner means the app is not idle, rather than a specific spinner?

Insufficient ReadMe

Hi @chiuki, a detailed Read me explaining how to get started would be really helpful. Thanks. 😊

Update with examples of new AndroidX.Test APIs

I am super excited about the future of Espresso from the recent talks at the Android Dev Summit.

Would love to see this repo updated with the new AndroidX.Test APIs
