Conquering the "Immersive Mode Confirmation" with Espresso 2.2.2
The Problem: When testing Android apps using Espresso 2.2.2, you might encounter a peculiar obstacle: the "Immersive Mode Confirmation" dialog. This dialog appears when your app attempts to enter immersive mode, asking the user to confirm their intent. This can disrupt your automated tests, leading to unexpected failures and frustrating delays.
Rephrasing: Imagine your app is trying to go fullscreen (like a game or a video player). Suddenly, a pop-up appears, asking the user if they really want to go fullscreen. This is the "Immersive Mode Confirmation." While helpful for users, it can be a nuisance for your automated tests, as Espresso might not be able to interact with your app properly until the user confirms.
Scenario and Code:
@Test
public void testFullscreenMode() {
onView(withId(R.id.fullscreenButton)).perform(click());
// ... Test fullscreen mode functionality
}
In this example, clicking the "fullscreenButton" triggers the immersive mode. However, the test might fail if the "Immersive Mode Confirmation" dialog pops up, blocking the app from entering fullscreen.
Insights and Solutions:
There are a few ways to address this issue:
1. Embrace the Confirmation:
- Accept the Dialog: Modify your test to explicitly handle the confirmation dialog. Use Espresso's
onViewandperformmethods to interact with the dialog and accept it, allowing your test to proceed.
@Test
public void testFullscreenMode() {
onView(withId(R.id.fullscreenButton)).perform(click());
onView(withText("Confirm")).perform(click()); // Click the "Confirm" button
// ... Test fullscreen mode functionality
}
- Disable the Dialog: For development and testing purposes, you can disable the "Immersive Mode Confirmation" dialog in your app's settings. This may not be ideal for production but can streamline your testing process.
2. Embrace the Power of Espresso:
- Idle Resources: Use
IdlingResourceto ensure Espresso waits until your app is ready before interacting with it. Create anIdlingResourcethat signals when the immersive mode confirmation has been handled, either by accepting it or disabling it.
3. Custom Actions:
- Custom
clickAction: You can create a customclickaction that performs additional steps to address the immersive mode confirmation. For example, you can use aViewActionthat waits for the confirmation dialog to appear and clicks the confirmation button.
4. The Power of Workarounds:
- Delay: A simple yet not ideal solution is to introduce a small delay in your test code after triggering the immersive mode. This gives the confirmation dialog time to appear and potentially be handled. Use this approach with caution, as it can make your tests brittle and unreliable.
Additional Value:
- Optimize Your Code: The best approach is to integrate the confirmation handling into your app's logic. For example, you could use an
Activitycallback to handle the confirmation dialog and ensure your app proceeds smoothly.

Conclusion:
The "Immersive Mode Confirmation" is a potential hurdle when using Espresso. By understanding its behavior and implementing appropriate strategies, you can overcome this obstacle and ensure your automated tests are robust and reliable.
