Is there a way out that i can perform actions using espresso once i leave my application to some external application?
I am opening android image picker and want to select an image from the activity
Generally, this is not possible with Espresso. You will get a SecurityException, if you send events to any window controlled by a different user id.
Here are a few things you could try:
create a custom AOSP build and disable the security checks
for API 16+ you can use uiautomator tests instead of instrumentation tests
on API 18+ you can use instrumentation.getUIAutomation()

I am trying to automate my android application. When I start the test I try to switch environment from the debug drawer. While switching environment the application closed and opens a new instance for that particular environment. The test fails the time the application closes.
Getting this error: Reason: 'Instrumentation run failed due to 'Process crashed.''
IS there any way the script does not fail and wait until the new application opens
You need to use uiautomator along with espresso for this kind of use cases.Use Uiautomator to switch the environment and then let the espresso steps run.
For more details refer-https://developer.android.com/topic/libraries/testing-support-library/index.html#UIAutomator
The UI Automator testing framework provides a set of APIs to build UI tests that perform interactions on user apps and system apps. The UI Automator APIs allows you to perform operations such as opening the Settings menu or the app launcher in a test device. The UI Automator testing framework is well-suited for writing black box-style automated tests, where the test code does not rely on internal implementation details of the target app.
onView(withId(R.id.BUTTON))
.perform(click())
.check(matches(withContentDescription(R.id.my_layout)));
onView(withId(R.id.tp_layout))
.check(matches(isDisplayed()));
I am trying to test whether button click migrates to next screen or not..
how can I match, with this only first test is running and it displays tests failed.
You can use an Espresso extension - Espresso-Intents.
Here is the official tutorial.
Quick quote:
Espresso-Intents is an extension to Espresso, which enables validation
and stubbing of intents sent out by the application under test. It’s
like Mockito, but for Android Intents.
If your app delegates functionality to other apps or the platform, you
can use Espresso-Intents to focus on your own app's logic while
assuming that other apps or the platform will function correctly. With
Espresso-Intents, you can match and validate your outgoing intents or
even provide stub responses in place of actual intent responses.
My android app has a service which sends notifications to user based on parameters like number of runs of the app. The notifications are sent at different times in different situations. I want to test whether notifications are sent at the right times in all the different cases. Does android provide a way of such a testing ?
Testing Notification using UIAutomator:
Just go through the below code. It will help you in testing the notification.
UiDevice device = UiDevice.getInstance(InstrumentationRegistry.getInstrumentation());
device.openNotification();
device.wait(Until.hasObject(By.text(NOTIFICATION_TITLE)), TIMEOUT);
UiObject2 title = device.findObject(By.text(NOTIFICATION_TITLE));
UiObject2 text = device.findObject(By.text(NOTIFICATION_TEXT));
assertEquals(NOTIFICATION_TITLE, title.getText());
assertEquals(NOTIFICATION_TEXT, text.getText());
title.click();
device.wait(Until.hasObject(By.text(ESPRESSO.getName())), TIMEOUT);
Don't forget to add the UIAutomator dependencies in build.gradle.
// UIAutomator dependency
androidTestCompile 'com.android.support.test.uiautomator:uiautomator-v18:2.1.1'

Here is a nice explanation of this topic:
Espresso for Android is perfect and fast test automation framework,
but it has one important limitation - you are allowed to operate only
inside your app under test context.
This means, it is not possible to automate tests for app features such as:
application push notifications
contact synchronization
navigating from another app to your app under test,
Since you have to deal with other apps from the mobile device -
NotificationBar, Contacts or People app, etc.
In fact it wasn't possible until the release of UIAutomator 2.0. As
stated in Android Developers blog post - "...Most importantly, UI
Automator is now based on Android Instrumentation...". And because
of that we can run UIAutomator tests as well as Espresso tests
using Instrumentation test runner.
In addition to that we can combine UIAutomator tests together with
Espresso tests and this gives us the real power and control over the
phone and application under test.
I have a scenario to test:
In my app, click a button - say, btn1.
btn1 click uses an intent action=VIEW, uri=http://www.m10v.com, category=DEFAULT to launch another activity. This activity belongs to another package (e.g.: browser)
How do I:
Ensure that an application with an activity this intent filter is installed?
How do I test that the activity actually started?
Robolectric should be used for unit testing your code. It stubs out the android runtime, allowing for a fast test/refactor cycle. Tests run on the JVM and not on an emulator or device. Therefore you cannot use it for interacting with other components in the system.
For your scenario there are two options:
Write a unit test and only verify interactions, i.e. checking Intent attributes. You can use Robolectric or ActivityUnitTestCase for that.
Write a functional Ui test using the UiAutomator Framework (Api 16) or use the new UIAutomation Apis introduced with Api 18.
I am trying to automate android app(Relocation services)using robotium. In this app there are media section and email and phone native dialer options so when i click on any of this option(Video, audio, phone, email) it takes you to the native app(video,audio, phone, email) of the phone. So how to handle external application activity using robotium(Like click on back button to come back to my app, or close native camera or video app to come back to my app)
Any answer will be great help.
You can only access your own app from within the instrumentation framework.
There are some options:
remove the default apps and add some fake apps to handle the intent (see https://github.com/bryanl/FakeCamera) for an example. to remove the app: http://oneclickandroid.blogspot.de/2009/01/how-to-remove-defaultpreloaded.html
resign the apps you want to control with your key so you can instrument them (see http://code.google.com/p/robotium/wiki/RobotiumForPreInstalledApps)
install your app with system permissions ( Android INJECT_EVENTS permission ), but haven't tried method yet
Sorry to bump this...
I've just put the camera stub and gallery stub that I made / use on the play store... thought might be of use to you / others for testing the camera and gallery in automated tests :)

I think, Using Robotium you can't access other application resources from your target testing application.
Just use Instrumentation for this,
Instrumentation inst = new Instrumentation();
inst.sendKeyDownUpSync(KeyEvent.KEYCODE_BACK);
But be sure if you are doing this in Activity then put this in separate thread for run this code..
