AmbiguousViewMatcherException with recycler views

[vkosovskii]

Steps to reproduce:

On the ViewPager I have three RecyclerViews and when I just try to check "rvAppsList.isVisible()" test failed and shows an error: androidx.test.espresso.AmbiguousViewMatcherException: '(with id: com.malwarebytes.antimalware.cloud:id/rvAppsList)' matches multiple views in the hierarchy. Problem views are marked with 'MATCHES' below.

Create a recycler view:

// Apps list
    val rvAppsList = KRecyclerView({
        withId(R.id.rvAppsList)
    }, itemTypeBuilder = {
        itemType(YourAppsScreen::ListItems)
    })

    class ListItems(parent: Matcher<View>) : KRecyclerItem<ListItems>(parent) {
        val ivAppIcon = KImageView(parent) { withId(R.id.iv_app_icon) }
        val tvAppName = KTextView(parent) { withId(R.id.tv_app_name) }
        val tvAppPackageName = KTextView(parent) { withId(R.id.tv_app_package_name) }
        val tvAppLastUpdate = KTextView(parent) { withId(R.id.tv_app_last_update) }
    }

Failing on the step "isVisible"

private fun isMyLabelIsVisible(): Boolean {
        return try {
            yourAppsScreen.rvList.isVisible()
            true
        } catch (e: AssertionFailedError) {
            false
        } catch (e: NoMatchingViewException) {
            false
        }
    }

Observed Results:

androidx.test.espresso.AmbiguousViewMatcherException: '(with id: com.malwarebytes.antimalware.cloud:id/rvAppsList)' matches multiple views in the hierarchy.
Problem views are marked with '****MATCHES****' below.

Hi and thanks for reaching out. Although, the recycler views in your ViewPager are not displayed, pager works in a fashion that keeps at least 3 pages active, which means the non-displayed recyclers are present within the view hierarchy, thus the ambiguous match exception. The easiest thing to do is to match the actively displayed recycler in your case:

val rvAppList = KRecyclerView({
    withId(R.id.rvAppList)
    isDisplayed() // or isCompletelyDisplayed()
}, ...

I hope that helps 👍

Yes! Thanks a lot!! isCompletelyDisplayed() completely solved my problem.
