Instrumentation tests for API 24 and lower stucking on clickNext() and failing with timeout

[jluiz20]

Hi.

First of all, congratulations on the great library.

I am running the following test:

@Test public void test_step02_onNext() { //given activityRule.getActivity().runOnUiThread(() -> { viewArgumentCaptor = ArgumentCaptor.forClass(TurnVehicleOnContract.View.class); verify(presenter).onViewResume(viewArgumentCaptor.capture()); }); //when onView(withId(R.id.stepperLayout)).perform(clickTabAtPosition(1)); onView(withId(R.id.stepperLayout)).perform(clickNext()); //then checkCurrentStepIs(2); clearInvocations(presenter); }

It runs ok on API level 25 but when I run on 24 or lower it fails. I have debugged and it stucks on the line of clickNext() action. onView(withId(R.id.stepperLayout)).perform(clickNext()); .

Visually it goes to the next step but for some reason in the code it does not proceed to the next line of code.

This is the version I am using implementation 'com.stepstone.stepper:material-stepper:4.3.1' androidTestImplementation('com.stepstone.stepper:espresso-material-stepper:4.3.1', { exclude group: 'com.android.support.test.espresso' })

Here is the log for reference `android.support.test.espresso.AppNotIdleException: Looped for 3586 iterations over 60 SECONDS. The following Idle Conditions failed .

Hi @jluiz20, It's hard to determine by just looking at the stack trace and without seeing the rest of your code :( Are you able to reproduce the same behavior in the sample app from this library? Also, are the animations disabled on both devices?

[jluiz20]

I found the problem.

Even with the animations disabled on the emulator there was one indeterminate ProgressBar on the step that was opening that was messing with everything. So, my bad.

Sorry for bothering you. You may close the issue. Congrats for the library, Cheers!

I'm very happy someone is using espresso-material-stepper as I wasn't sure whether it's worth the effort to expose it as a public module. Glad I did :)
