Espresso Descendant Actions

Adding support for accessing descendant child views such as a button contained within the root view of a row/column element in the recycler view for testing with espresso.

Latest version

For history on this project see my blog post

Basic Usage

Checking state of the specific adapter view at position 5:

onView(withId(R.id.recyclerView)).perform(
    actionOnItemAtPosition(5,
        DescendantViewActions.checkViewAction(matches(isCompletelyDisplayed())))
);

Checking state of a descendant view:

onView(withId(R.id.recyclerView)).perform(
    actionOnItemAtPosition(5,
        DescendantViewActions.checkDescendantViewAction(
            withId(R.id.favoriteButton), matches(withContentDescription(R.string.favorite))))
);

Performing an action on a descendant view:

onView(withId(R.id.recyclerView)).perform(
    actionOnItemAtPosition(5,
        DescendantViewActions.performDescendantAction(withId(R.id.favoriteButton), click()))
);

See the sample project for a functional example.
