Espresso withText in TextView Seçili eşleşme görüntülenmiyor. Göster View

Question

Espresso'yla tek bir test hatası yapıyorum. Aşağıda, görüntülenen bir iletişim kutusunda bir TextView test etmektir. Aşağıdaki hatayı alıyorum:

com.google.android.apps.common.testing.ui.espresso.base.DefaultFailureHandler$AssertionFailedWithCauseError: 'with string from resource id: <2131099772>' doesn't match the selected view. 
Expected: with string from resource id: <2131099772>[my_content] value: Test Content Available 
Got: "TextView{id=2131296340, res-name=dialog_content, visibility=VISIBLE, width=620, height=38, has-focus=false, has-focusable=false, has-window-focus=true, is-clickable=false, is-enabled=true, is-focused=false, is-focusable=false, is-layout-requested=false, is-selected=false, root-is-layout-requested=false, has-input-connection=false, x=0.0, y=0.0, text=Test Content Available, input-type=0, ime-target=false}"

Yani açıkça, görünüm bulunur ve bunun ayrıntıları var içinde, sen değer Beklediğim = metni görebilirsiniz. Yine de uymuyor diyor. Görüntüle istisna görünümü hiyerarşisinde gösterir bile aracılığıyla şu testi açıklamada

onView(withId(R.id.dialog_content)).check(
       matches(withText(R.string.my_content))); 

ben de aşağıdaki deyimi ile yapıyor çalıştı, ancak bir NoMatchingViewException var olan çalıştırılır.

onView(withText(R.string.my_content)).check(
       matches(isDisplayed())); 

bu başarısız neden üzerinde herhangi bir yardım? Ifade ile bir kardeşi alanda withText() isDisplayed() yapabiliyorum dikkati.
