Check if a dialog is displayed with Espresso

Question

I\'m trying to write some tests with the new android-test-kit (Espresso). But I can\'t find any information on how to check if a dialog is displayed and per

Answer 1

1. To verify if dialog appears you can simply check if View with a text that present inside the dialog is shown:

   onView(withText("dialogText")).check(matches(isDisplayed()));
   

   or, based on text with id

   onView(withId(R.id.myDialogTextId)).check(matches(allOf(withText(myDialogText), isDisplayed()));
   

2. To click on dialogs button do this (button1 - OK, button2 - Cancel):

   onView(withId(android.R.id.button1)).perform(click());
   

   UPDATE

3. I think is possible since Espresso has multi window support.
4. Not sure about clicking outside the custom dialog view but for checking if it is displaying or not you have to create your custom matcher and check inside it.
