我在Android Studio工作。我目前正致力于使用Espresso 2.1创建自动化测试:
androidTestCompile 'com.android.support.test.espresso:espresso-core:2.1'
我有以下针对MainActivity类的xml布局:
<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>
我尝试做的是验证上面xml的第二个ImageButton是否显示。我的代码是:
@SmallTest
public void testSelectableLayersIsOpen()
{
onView((withId(R.id.btnSelectableLayers))).check(matches(isDisplayed()));
}
代码只工作了一次。测试成功通过一次。在我第二次尝试运行测试(以及更多次)后,我收到了同样的错误:
android.support.test.espresso.NoMatchingViewException: No views in hierarchy found matching: with id: <package_name>:id/btnSelectableLayers

我不知道它为什么会发生。 此外,如果我在代码中添加一个新行 - 测试将再次传递,并且只会再次传递一次。 在我的情况下,我已经在上面的xml中添加了下一行:
android:contentDescription="theMainMapViewFirst">
我的测试已经过了绿色。但只有一次。它刚刚在下一次运行时再次失败。
你能帮我解决这类问题吗?
答案 0 :(得分:3)
当espresso尝试查找视图时,您似乎在活动顶部显示了一个对话框。
查看espresso异常中输出的View Hierarchy转储,找出它是什么对话以及它出现的原因。
