I work in Android Studio. I'm currently working on automation tests creation using Espresso 2.1:
androidTestCompile 'com.android.support.test.espresso:espresso-core:2.1'
I have following xml layout for MainActivity class:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent"
android:layout_height="match_parent" tools:context=".MainActivity">
<com.esri.android.map.MapView
android:id="@+id/mapView"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:contentDescription="theMainMapViewFirst">
</com.esri.android.map.MapView>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="horizontal" android:layout_width="match_parent"
android:layout_height="wrap_content" android:id="@+id/toolbarLayout" android:background="@color/toolbar_bg">
<View
android:layout_width="0dp"
android:layout_height="1dp"
android:layout_weight="1" >
</View>
<ImageButton
android:id="@+id/btnPanMode"
android:layout_width="wrap_content"
android:background="@null"
android:onClick="onPanClick"
android:layout_height="wrap_content"
android:padding="3pt"
android:src="@drawable/map_pan"/>
<View
android:layout_width="0dp"
android:layout_height="1dp"
android:layout_weight="1" >
</View>
<ImageButton
android:id="@+id/btnSelectableLayers"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:padding="3pt"
android:src="@drawable/layer_basemap_analyze32"
android:onClick="onSelectableLayersClick"
android:scaleType="fitXY"
android:background="@null" />
<View
android:layout_width="0dp"
android:layout_height="1dp"
android:layout_weight="1" >
</View>
</LinearLayout>
What I'm trying to do is to verify the second ImageButton from xml above is displayed. My code is:
@SmallTest
public void testSelectableLayersIsOpen()
{
onView((withId(R.id.btnSelectableLayers))).check(matches(isDisplayed()));
}
The code has worked only one time. And the test was successfully passed only once. After I tried to run the test second time (and a lot of more times) I receive the same error:
android.support.test.espresso.NoMatchingViewException: No views in hierarchy found matching: with id: <package_name>:id/btnSelectableLayers

I have no idea why it's happening. Also, if I'm adding a new line to the code - the test will passed again, and only one time again. In my case I've added next line to the xml above:
android:contentDescription="theMainMapViewFirst">
and my test has passed green. But only one time. It was failed again on just next run.
Could you guys please help me with such kind of issue?
