Select Date from Calendar in Android Espresso

Question

I am testing an Android app with Espresso. I have an EditText widget with androidInputType=date. When I touch this control with my finger, a calendar pops up for me to select the date.

How do I automate this in Espresso? I've looked all over the place and I can't figure it out. typeText() certainly does not work.

can you show the ids and their data type. calendar id which you need to click. — Jitesh Mohite, Apr 01 '17 at 10:01

Original answered by me here, but in the scope of another question: Recording an Espresso test with a DatePicker - so I repost my adapted answer from there:

Use this line to set the date in a datepicker:

onView(withClassName(Matchers.equalTo(DatePicker.class.getName()))).perform(PickerActions.setDate(year, monthOfYear, dayOfMonth));

This uses the PickerActions which is part of the espresso support library - the espresso-contrib. To use it, add it like this to your gradle file (You need several excludes to prevent compile errors due to mismatching support library version):

androidTestCompile('com.android.support.test.espresso:espresso-contrib:2.2.2') {
    exclude group: 'com.android.support', module: 'appcompat'
    exclude module: 'support-annotations'
    exclude module: 'support-v4'
    exclude module: 'support-v13'
    exclude module: 'recyclerview-v7'
    exclude module: 'appcompat-v7'
}

Then you could create a helper method which clicks the view that opens the datepicker, sets the date and confirms it by clicking the ok button:

public static void setDate(int datePickerLaunchViewId, int year, int monthOfYear, int dayOfMonth) {
    onView(withParent(withId(buttonContainer)), withId(datePickerLaunchViewId)).perform(click());
    onView(withClassName(Matchers.equalTo(DatePicker.class.getName()))).perform(PickerActions.setDate(year, monthOfYear, dayOfMonth));
    onView(withId(android.R.id.button1)).perform(click());
}

And then use it like this in your tests:

TestHelper.setDate(R.id.date_button, 2017, 1, 1); 
//TestHelper is my helper class that contains the helper method above

I had to replace "2.2.2" with "2.2" to avoid build conflicts. — Hack06, Feb 16 '18 at 14:04
Note: the `PickerActions.setDate` can pick a date which is disabled for the user. — Stumi, Feb 01 '19 at 13:35
In order to make it work, I had to use `isAssignableFrom(DatePicker.class)` instead of `withClassName(Matchers.equalTo(DatePicker.class.getName()))` — Tushar Kathuria, May 28 '20 at 10:16
