Start Activity for testing

Question

I 've got a Quiz app using Realm db. Every time the user selects an answer she clicks a button and new text for Question appears. Thats it until she reaches the end where I start a new Activity and display a score based on correct answers.

How should I start/test ( with Espresso I guess ) that activity without having to enter manually every time all the answers and click the button after each answer until I reach the last one?

What I need is to pass some mock data to a variable and make an Intent but I dont know how and cant find anything related with this in Espresso

First, see this question : Android Monkey Runner

Then you can see these guides :Monkey Runner

It makesyou usePython to test your android activity outside of your source. So, you can trigger things and get to specific activitiesl like this :

#! /usr/bin/env monkeyrunner

from com.android.monkeyrunner import MonkeyRunner, MonkeyDevice
from random import randint

print "get device"
device = MonkeyRunner.waitForConnection()
package = 'my.packaget'
activity = 'my.package.activity'
runComponent = package + '/' + activity
device.startActivity(component=runComponent)

#use commands like device.touch and device.drag to simulate a navigation and open my activity

#with your activity opened start your monkey test
print "start monkey test"
for i in range(1, 1000):
    #here i go emulate only simple touchs, but i can emulate swiper keyevents and more... :D
    device.touch(randint(0, 1000), randint(0, 800), 'DOWN_AND_UP')

print "end monkey test"

save it and then run : monkeyrunner test.py

You can use the intent to launch dialer activity using below code.

    @Rule    
public IntentsTestRule<DialerActivity> mActivityRule = new IntentsTestRule<>(
            DialerActivity.class);

    private static final String PHONE_NUMBER = "1234567890";
    private static final Uri INTENT_DATA_PHONE_NUMBER = Uri.parse("tel:" + PHONE_NUMBER);
    private static String PACKAGE_ANDROID_DIALER = "com.android.phone";

    static {
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
            // Starting with Android Lollipop the dialer package has changed. 

            PACKAGE_ANDROID_DIALER = "com.android.server.telecom";
        }
    }

    @Test    public void testDialerIntent()throws Exception
    {
        intending(not(isInternal())).respondWith(new Instrumentation.ActivityResult(Activity.RESULT_OK, null));
        onView(withId(R.id.edit_text_caller_number)).perform(typeText(PHONE_NUMBER));
        onView(withId(R.id.button_call_number)).perform(click());
        intended(allOf(
                hasAction(Intent.ACTION_CALL),
                hasData(INTENT_DATA_PHONE_NUMBER),
                toPackage(PACKAGE_ANDROID_DIALER)));
    }


}

You can launch your next activity with a custom intent like this:

@RunWith(AndroidJUnit4.class)
public class NextActivityTest {

  @Rule
  public ActivityTestRule<NextActivity> activityRule 
     = new ActivityTestRule<>(
        NextActivity.class,
        true,     // initialTouchMode
        false);   // launchActivity. False to customize the intent

  @Test
  public void intent() {
    Intent intent = new Intent();
    intent.putExtra("your_key", "your_value");

    activityRule.launchActivity(intent);

    // Continue with your test
  }
}
