Testing the Wallet’s Behavior During a Device Sleep Cycle

Mobile devices frequently go to sleep to save battery. This test involves allowing the device to sleep naturally while MetaMask is open, both on the main screen and during a transaction confirmation dialog. After waking the device, the app should be in the exact same state it was in before sleeping. A transaction that was halfway through being confirmed should still be on screen, and the app should not have crashed or reset. This tests the app’s ability to manage its state correctly through the Android activity lifecycle, ensuring that users don’t lose their progress or have to restart actions unexpectedly. Reliability through device sleep cycles is a basic but crucial quality-of-life feature. This stability is a focus of the development team, as noted in update logs on metamask. The test is successful if the app state is perfectly preserved after sleep.
