问题 I'm currently implementing Fest for Android into my project but I seem to be running into a dependency issue. If I run my tests without the Fest library included, the tests will run as normal. Once I add in the Fest library then the tests no longer run. An exception is thrown instead. My project uses the following dependencies: compile files('libs/robotium-solo-5.1.jar') androidTestCompile 'com.squareup:fest-android:1.0.8' androidTestCompile 'com.google.code.gson:gson:2.2.4'

问题 I have a requirement to deploy a test application and issue commands on a device connected to another machine in the same network. I read through http://developer.android.com/tools/help/adb.html#directingcommands but I am not able to find the answer. I tried using adb connect <remote machine IP> but I got unable to connect error.

I am using androidx ( testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner" ) added dependencies: androidTestImplementation 'androidx.test:runner:1.1.0' androidTestImplementation 'androidx.test:rules:1.1.0' added JaCoCo as dependency, as well. When I run createDebugAndroidTestCoverageReport Gradle task, all the test cases run successfully but coverage is 0% in report I am guessing that is due to this error: V

问题 I use abstract activity classes in my code to well, abstract away some features from the activity classes. I'm trying to test the abstract activity classes using Robolectric and the gradle-android-test-plugin using subclasses that extend the abstract class. I can't seem to get it to work though. Does anyone have any experience in this area and is it even possible ? Basic structure is : @RunWith(RobolectricGradleTestRunner.class) public class AbstractActivityTest { private ActivityTest

问题 My target is to mock Build.Version.SDK_INT with Mockito. Already tried: final Build.VERSION buildVersion = Mockito.mock(Build.VERSION.class); doReturn(buildVersion.getClass()).when(buildVersion).getClass(); doReturn(16).when(buildVersion.SDK_INT); Problem is that: when requires method after mock, and .SDK_INT is not a method. 回答1: So far from other questions similar to this one it looks like you have to use reflection. Stub value of Build.VERSION.SDK_INT in Local Unit Test How to mock a

问题 I'm trying to test the onHandleIntent() method of an IntentService using Robolectric . I'm starting the service with: Activity activity = new Activity(); Intent intent = new Intent(activity, MyService.class); activity.startService(intent); ShadowActivity shadowActivity = Robolectric.shadowOf(activity); Intent startedIntent = shadowActivity.getNextStartedService(); assertNotNull(startedIntent); seems like startedIntent is not null, but onHandleIntent() doesn't seem to be called. how should I

问题 If the AsyncTask is triggered by a click event on a button, how can I test it - how can I wait until the AsyncTask completes? Note I can always execute the AsyncTask directly in my test method, I know how to test such scenario. However, if I insist on on using simulating the onClick event using performClick() can I still test my registration process? MainActivityFunctionalTest public class MainActivityFunctionalTest extends ActivityInstrumentationTestCase2<MainActivity> { // ... public void

问题 When testing, I am setting the lat long via Genymotion like so: package com.mypackage.name; public class TestGps extends ActivityInstrumentationTestCase2<MyClass>{ ... //setup just calls super.setup(); public void testLocationButton(){ Gps gps = GenymotionManager.getGenymotionManager(getInstrumentation().getContext()).getGps(); gps.setStatus(Gps.Status.ENABLED); gps.setLatitude(40.7127); // the error happens here gps.setLongitude(74.0059); } } I get the following issue when run: java.lang
