Dismiss Alert Dialog in Android Espresso Test

Question

I've looked around for solution for this but can't find one. I'm creating an Espresso Test and need to dismiss an Alert Dialog that appears in the middle of the screen the first time a particular Activity screen is displayed. There are no buttons on the dialog so to dismiss it the user needs to click anywhere outside the box. Does anyone know how I can do this with Espresso. I tried clicking on a layout on the underlying screen but Espresso fails saying that view cannot be found in the hierarchy.

Answer 1

Use onView(withText("alert_dialog_text")).perform(pressBack()); this must dismiss your dialog.

Answer 2

first check if the alert dialog is shown, if yes then perform pressBack click event

onView(withText("OK")).inRoot(isDialog()).check(matches(isDisplayed())).perform(pressBack());

replace the OK text with the text displayed on dialog

Answer 3

Espresso can't do this.

You need to use uiautomator inside your Espresso test, add this to your project's gradle:

androidTestCompile 'com.android.support.test.uiautomator:uiautomator-v18:2.1.1'

After your dialog appears, you can click on the screen at any coordinate:

UiDevice device = UiDevice.getInstance(getInstrumentation());
        device.click(x,y);

That will close your dialog
