问题 I am trying to test EditTexts in my form that are within a NestedScrollView. I am running the following code: onView(withId(R.id.register_scroll_view)).perform(scrollTo()).perform(click()); where register_scroll_view is my NestedScrollView. However, I am getting an exception: android.support.test.espresso.PerformException: Error performing 'scroll to' on view 'with id: com.eazyigz.myapp:id/register_scroll_view'.

问题 I'm trying to test, if newly created Activity (after orientation change) is properly reinitialized. The code below shows that activity returned from getActivity() is the one constructed in setUp(), not the newly created one. Test: public class MyActivityTest extends ActivityInstrumentationTestCase2<MyActivity>{ private static final String TAG = "RAMPS"; private MyActivity mActivity; public MyActivityTest() { super("com.ramps", MyActivity.class); } protected void setUp() throws Exception {

问题 I want get text string shown in a textview in LinearLayout. can espresso do that?　If not, is there other way to do that or can I use android api in espresso test case? I am using API 17 18 or newer, espresso 1.1(It should be the latest one.). I have no clue about this. Thanks. 回答1: The basic idea is to use a method with an internal ViewAction that retrieves the text in its perform method. Anonymous classes can only access final fields, so we cannot just let it set a local variable of getText(

问题 Does Android DDMS provide APIs ? I need to automate the snapshot mechanism for the native heap. Or is there any post processing tool for analysis DDMS native heap snapshots. 回答1: I assume by snapshot you mean a heap dump. From your app code you can call Debug.dumpHprofData() to dump the data. From a script you can call adb shell am dumpheap <process> <file> where <process> is e.g. your process id or name, and <file> is the dump file name. After that you can adb pull the dump to your computer.

问题 I've implemented access to a database using SQLiteOpenHelper from the android.database package within some classes (with pattern DAO). I wrote some junit tests for these classes using an AndroidTestCase but this causes the tests to use the same database as the application. I read that the ProviderTestCase2 or RenamingDelegatingContext can be used to test the database separately. Unluckily I couldn't find any nice tutorial/example that shows how to test a database with ProviderTestCase2

问题 I know it is possible for Espresso to click by bounds the way UiAutomator does. (x and y coordinates) I have read through the documentation but I can't seem to find it. Any help is appreciated. Thanks Edit I found this link, but no examples how to use it, My main concern with this is the UiController is or how to use it. 回答1: Espresso has the GeneralClickAction, this is the underlying implementation of ViewActions click() , doubleClick() , and longClick() . The GeneralClickAction 's
