android-espresso

问题 I am using Espresso to write UI tests for my Android application and would like to mock http requests using MockWebServer. I need to mock authentication responses and sign in the user before the tests are run. Is there a way make the app use mockwebserver so that isntead of making actual requests, I can use respontes enqueued on mockwebserver. So far I have: public class AuthenticationTest { @Rule public ActivityTestRule<Authentication> mActivityTestRule = new ActivityTestRule<>

问题 With Espresso I try to scroll to a textview inside linearlayout - but I am getting this exception: android.support.test.espresso.PerformException: Error performing 'scroll to' on view 'with id: org.ligi.gobandroid_hd:id/final_points'. at android.support.test.espresso.PerformException$Builder.build(PerformException.java:83) at android.support.test.espresso.base.DefaultFailureHandler.getUserFriendlyError(DefaultFailureHandler.java:70) at android.support.test.espresso.base.DefaultFailureHandler

问题 I'm doing an Activity transition testing with Espresso but I don't know if this is the best way to do it: public void testStartLogin() { onView(withId(R.id.register)).perform(click()); onView(withId(R.id.login_password)).check(matches(isDisplayed())); onView(withId(R.id.login_show_password)).check(matches(isDisplayed())); } The last two are from the second activity but this looks horrible for me. Is there any different way? 回答1: Asserting something against a view that belongs to a certain

问题 Basically I am trying to test that after login incorrectly I have an error showing in the email field. The view is: <android.support.design.widget.TextInputLayout android:id="@+id/ti_email" android:paddingEnd="10dp" android:paddingTop="10dp" android:paddingLeft="10dp" android:paddingRight="10dp" android:paddingStart="10dp" android:layout_width="match_parent" android:layout_height="wrap_content"> <EditText android:id="@+id/et_email" android:layout_width="match_parent" android:layout_height=

问题 I´m looking for a way to test an Activity with JUnit4 and the ActivityTestRule, but with a different application class (e.g. mocked or inherited). I was able to get this for library projects using the manifest merge and tools:replace="android:name" on the application tag in the androidTest/AndroidManifest.xml. This however does not work for applications. Any ideas how this can be done? 回答1: You can subclass the AndroidJUnitRunner with your own runner and override newApplication() with your

问题 I am using Espresso 2.1 with ActivityTestRule, and I am looking for a way to set some static flags before onCreate() in my application will be called. I have some init code that I don't want called during instrumentation tests. 回答1: Application onCreate() is called after Instrumentation onCreate() . For this case you need to implement a custom test runner which will subclass AndroidJUnitRunner and will override the callApplicationOnCreate() with your custom setup. public class

问题 I'm attempting to update an EditText as part of an Espresso test with: onView(allOf(withClassName(endsWith("EditText")), withText(is("Test")))).perform(clearText()) .perform(click()) .perform(typeText("Another test")); However I receive the following error: com.google.android.apps.common.testing.ui.espresso.NoMatchingViewException: No views in hierarchy found matching: (with class name: a string ending with "EditText" and with text: is "Test") By breaking down the test line I can see that

问题 It looks like CoordinatorLayout breaks the behaviour of Espresso actions such as scrollTo() or RecyclerViewActions.scrollToPosition() . Issue with NestedScrollView For a layout like this one: <android.support.design.widget.CoordinatorLayout android:layout_width="match_parent" android:layout_height="match_parent"> <android.support.v4.widget.NestedScrollView android:layout_width="match_parent" android:layout_height="wrap_content" app:layout_behavior="@string/appbar_scrolling_view_behavior"> ...

问题 I have a ViewPager whith items containing only a picture and a button. I can't successfully interact with the UI of an item (Page) because, except the displayed picture, there is nothing to differentiate (from UI point of view) all items of the ViewPager . I tried to select only one item with a position: onData(is(instanceOf(ItemClass.class))) .atPosition(0) .onChildView(withId(R.id.button)) .perform(click()); causing: NoMatchingViewException: No views in hierarchy found matching: is
