Espresso in Android Studio and NoClassDefFoundError
android,android-studio,android-espresso
The solution is very simple, just change this lines in your gradle.build: androidTestCompile 'com.jakewharton.espresso:espresso:1.1-r3' androidTestCompile('com.jakewharton.espresso:espresso-support-v4:1.1-r3') by adding exlude for compatibility library: androidTestCompile 'com.jakewharton.espresso:espresso:1.1-r3' androidTestCompile('com.jakewharton.espresso:espresso-support-v4:1.1-r3') { exclude group: 'com.android.support' } ...
Simulate user click in system activities with Android Espresso framework
android,android-bluetooth,android-testing,android-espresso
You can use UIAutomator for this purpose. It is possible to combine Espresso tests with UIAutomator in one test case. The only limitation is that it requires API level 18+ which can be achieved by adding flavor in your build.gradle file.
Espresso 2.1 doesn't find my tests
android,gradle,android-espresso
I managed to reproduce your situation by setting the wrong android.test.InstrumentationTestRunner in the test configuration. I would suggest checking if you have the correct one -android.support.test.runner.AndroidJUnitRunner- (or none) specified in the Run menu | Edit Configurations. Also, your question's title is somewhat confusing, since from the build gradle dependencies, my...

Dagger code giving NoClassDefFoundError when Espresso Tests are run, normal run works fine
android,android-testing,dagger,android-espresso
This issue had me for a bit. You likely need to exclude javax.inject from the espresso dependency. Earlier versions of Android appear to be less tolerant of identical dependencies. Something along the lines of: androidTestCompile ('com.android.support.test.espresso:espresso-core:2.0') { exclude group: 'javax.inject' } Beware that this can bite you all over the...

What JARs are needed for Espresso testing?
android,testing,android-espresso
You can download JARs here: https://code.google.com/p/android-test-kit/source/browse/#git%2Fbin%2Fespresso2.0 You probably want espresso-core-2.0.jar. You might also want to download the sources jar so that you can easily see what espresso methods are doing, but it's not required. espresso-contrib-2.0.jar has some extra utilities which you may or may not find useful. That said, I...

Espresso Android testing - using getActivity in a helper method (can't find method to import)
No, I don't think there's a clean/easy way to get the current Activity from outside of a test. However, you could do this cleanly with a custom view matcher.

Is there any way to know if an activity has been started with Espresso?
Asserting something against a view that belongs to a certain activity is in my opinion a very elegant way of checking if that specific activity has been started. From the official docs: At the same time, the framework prevents direct access to activities and views of the application because holding...
Espresso how to wait for some time(1 hour)?
android,junit4,android-testing,android-espresso
You need an IdlingResource with an isIdleNow() that returns true only if the specific amount of time has passed. To achieve that, save the start time and compare it with current time: public class ElapsedTimeIdlingResource implements IdlingResource { private final long startTime; private final long waitingTime; private ResourceCallback resourceCallback; public...

How to use Espresso Idling Resource
android,android-testing,android-espresso

Testing ViewPager with Espresso. How perfom action to a button of an Item?
android,android-viewpager,android-espresso,ui-testing

How to press editor action on Espresso
android,android-testing,android-espresso
"pressKey" expects a KEYCODE, not a FLAG. So pressKey(KeyEvent.FLAG_EDITOR_ACTION) doesn't really make sense and will definitely not work. But there is a ViewAction for pressing the editor (IME) action, see the static method: ViewActions#pressImeActionButton() You can view the Espresso 1.x implementation details here: https://android-test-kit.googlecode.com/git-history/master/espresso/lib/src/main/java/com/google/android/apps/common/testing/ui/espresso/action/EditorAction.java?r=master...
getting Dagger to inject mock objects when doing espresso functional testing for Android

java,android,android-testing,android-espresso,android-instrumentation
Thanks to @Gordak. His answer has almost worked. But, unfortunately, it blocks the main thread so the test never ends.

How can to test in Espresso without R.id.edit_text?
withId is only one of view matchers. You could you use others that are suitable for you case. You could check under ViewMatchers of com.google.android.apps.common.testing.ui.espresso.matcher. Google code could be found here. Also hamcrest matchers could help to have more complex conditions. One of samples could be this: onView(allOf(isAssignableFrom("class name"), withText("Text...
Espresso: how to click on StickyListHeadersListView item inside viewpager
I've found the solution myself. The main issue - StickyListHeadersListView is a wrapper around ListView, it doesn't extend ListView. So we can't work with adapter directly, but we can do this: onData(anything()).inAdapterView(allOf( isAssignableFrom(AdapterView.class), isDescendantOfA(withId(R.id.list)), isDisplayed())) .atPosition(1).perform(click()); ...

How can I perform a multi touch swipe with Espresso?

If you really want to do this, you can do FragmentManager fragmentManager = getActivity().getFragmentManager() and get information about the backstack from fragmentManager.

How to test Android UI using IdlingResource when using Retrofit network requests
