Is it possible to assert isDisplayed on multiple views with Espresso?
I am wondering if it is possible to create a custom matcher which can take all of the views specified and make an assertion on that array or collection.
As a potential example it would look like:
onView(
(withAllIds(R.id.text_view1,R.id.text_view2, R.id.text_view3))).check(matches(isDisplayed())
For clariy, the above would assert that textview 1, 2, and 3 are all displayed.
Whether or not this is a code smell or not, I am curious to hear thoughts and opinions. I would be using this to make a simple assertion that the expected views are shown at the UI level and perhaps pair it with isCompletelyDisplayed() to ensure nothing is clipped. Writing the tests/assertions separately would allow easier debugging if something fails, but would take longer time in the suite to have every test run separately on the CI.
Optionally, is there a better way to test these simple view assertions? Is it worth it?
I am usually a fan of testing an interaction with the app e.g. if the app actually does something, the UI handles it correctly, or if the API returns a response, then the UI handles it correctly.
But I am curious if using something like the everyItem Hamcrest example is possible for multiple views with Espresso.
