Add a sleep after every pager swipe?

[rocboronat]

When running tests on Firebases's real devices like the Samsung S9, I see that it doesn't wait after doing a swipe on a pager. So, if you make three swipes and then tap a button in the screen, the tap will be lost.

I solve it by adding sleeps after the swipes in the test. What about doing those sleeps in Barista?

It will make everyone's tests a bit slower, but it will save some headaches.

You can add loops for clickOn(). I wrote my own tryInLoop for click (asserts to) and now when the test wants to click Id it does it in a loop (for 5 second the test tries to click every second)

Sounds good! Thanks for the idea @rozautd 😀

Perhaps you could implement an IdlingResource that checks the state of the ViewPager?
Just had a look at the docs and the way to check the state is via ViewPager.OnPageChangeListener. More specifically if you override the onPageScrollStateChanged method, you can wait for the state SCROLL_STATE_IDLE which is described as follows:

Indicates that the pager is in an idle, settled state. The current page is fully in view and no animation is in progress.

There is an example here of using an IdlingResource to check the state of a Snackbar to give you an idea.

Hope that helps.
