I'm trying to figure out RecyclerView tests with espresso, I'm trying to use the RecyclerViewActions.scrollTo to scroll to the specified item in the RecyclerView .
onView(withId(R.id.rv_container)).perform(
RecyclerViewActions.scrollTo<ItemViewHolder>(
hasDescendant(
withText("Item: 40")
)
)
)
This is the error I get.
Error performing 'scroll RecyclerView to: holder with view: has descendant: with text: is "Item: 40"' on view 'with id is <com.example.endtoend:id/rv_container>'.
- Windows animation scale
- Transition animation scale
- Animator duration scale
are all turned off
I'm also not sure why I have to cast ViewHolder here, Android dev examples don't cast ViewHolder.
Aaron's trick to get the RecyclerViews ViewHierachy.
androidx.test.espresso.base.DefaultFailureHandler$AssertionFailedWithCauseError: 'not is displayed on the screen to the user' doesn't match the selected view.
Expected: not is displayed on the screen to the user
Got: "RecyclerView{id=2131231038, res-name=rv_container, visibility=VISIBLE, width=1440, height=1878, has-focus=false, has-focusable=true, has-window-focus=true, is-clickable=false, is-enabled=true, is-focused=false, is-focusable=true, is-layout-requested=false, is-selected=false, layout-params=androidx.constraintlayout.widget.ConstraintLayout$LayoutParams@4b6b49e, tag=null, root-is-layout-requested=false, has-input-connection=false, x=0.0, y=532.0, child-count=12}"
