android-espresso

问题 My project structure is as follows: :app , :core . :app is the Android application project, and it depends on :core which has all the business logic. I have Espresso tests for :app , and I am able to run and get coverage report thanks to all the questions and guides out there. But the coverage is only for code in :app . How do I get coverage for all projects ( :app and :core ) resulting from my Espresso instrumentation tests? Is this even possible? Any help is greatly appreciated. 回答1: Even

问题 I have a bunch of end-to-end instrumentation tests (relying on Espresso) that start our launcher activity, then navigate throughout our app (eventually creating several activities). At the end of each test our @After annotated tear down method performs some cleanup. The problem we have is that after the test finishes (successful or failed assertion) the app is still "running", so some of the cleanup is actually causing the app to crash. This is either resulting in false positives if the

问题 I'm trying to test my app behavior with Espresso-2.2 On main activity, when button pressed both service and another activity is being started: public class MainActivity extends Activity { public void onButtonClicked() { startActivity(SecondActivity.getStartIntent()); startService(MyIntentService.getStartIntent()); } } I'm testing if intended components are being started: public class MainActivityTest { @Rule public final IntentsTestRule<MainActivity> intentsRule = new IntentsTestRule<>

问题 I have a popupmenu. Uix screenshot provided. Now I want to verify some items in the list by clicking them and verify what's happening. But no matter what I do I don't seem to be able to select items in the popup menu. The menu does not have an id and I don't think it's possible to set an id of a menu. I've tried different things like: onView(nthChildOf(anyOf(withId(android.R.id.title)), 1)).perform(click()); onView(withText("5 sekunder")).perform(click()); But nothing works. How do I click on

问题 There are a lot of topics/questions regard this issue on stackoverflow (such as Error=Unable to find instrumentation info for: ComponentInfo{ }) and other website but the thing that make my problem different than others is I am working on automation. So let me give you more details. I have no problem when I'm testing on local machine (I mean my laptop). I can run Espresso testing and all tests passes. Now, I want to run these tests on CI (Bitrise in my case). I create and run Emulator. I

问题 I start my login activity and I use in Espresso test: onView(withId(R.id.username)).perform(typeText("USERNAME")); I expect the text in the field to be "USERNAME", but sometimes I get "SERNAME", others "UERNAME". Most of the times it works but sometimes it fails, specially after rebooting the phone. Here is the sample code to reproduce the bug: https://github.com/neoranga55/CleanGUITestArchitecture 回答1: The test phone uses Swift keyboard with double language typing enabled. Apparently this

问题 I am new to Espresso UI testing. I am getting this error while running tests (ADT Eclipse IDE ). The app is already developed and there are lots of request going on while launching the app. it is not possible to rewrite the app. but i need to find the way to test this UI even if there is any delay in the loading of the components. java.lang.RuntimeException: Could not launch intent Intent { act=android.intent.action.MAIN flg=0x14000000 cmp=com.xx.android/com.yy.core.android.map.MapActivity }

问题 I'm trying to write some UI tests for an Android APP with the espresso framework. For now I'm just checking if all the elements are present on the splash screen and then I'm trying to click the login button. When the the button is clicked the test fails due to an error that I can't seem to understand why it's happening. My test code is @RunWith(AndroidJUnit4.class) @SmallTest public class WelcomeTest { @Rule public ActivityTestRule<Welcome> mActivityRule = new ActivityTestRule<>( Welcome

问题 I'm trying to setup UI testing similar to GithubBrowserSample and it looks like the sample project only has mock ViewModel for Fragment but not an example for Activity . Here's my code where I am trying to test the Activity by mocking ViewModel . But the ViewModel is not getting set before onCreate() in Activity. @RunWith(AndroidJUnit4::class) class MainActivityTest { val viewModel = mock(MainViewModel::class.java) @Rule @JvmField val activityRule = ActivityTestRule<MainActivity>(MainActivity

问题 Android Studio 3.0 Beta2 I am testing getting a list for an endpoint using RxJava2. The app works fine when running normally. However, when I test using espresso I get a null pointer exception when I try and subscribeOn(scheduler) . For the schedulers I use the trampoline() for both subscribeOn and observeOn which are injected. Caused by: java.lang.NullPointerException: Attempt to invoke virtual method 'io.reactivex.Observable io.reactivex.Observable.subscribeOn(io.reactivex.Scheduler)' on a
