Mobile app testing covers installation, navigation, input, permissions, networking, storage, notifications, background behavior, accessibility, performance, security, and compatibility. Tests can run manually or through automated device tools on physical hardware, emulators, and simulators.
Real user flows matter because isolated component checks can miss lifecycle and integration failures. A coding agent can operate devices and interpret results, while stable assertions, logs, screenshots, and human review provide independent evidence of success.

Mobile app testing checks whether an app works properly on phones and tablets. It follows the actions real users take and looks for broken screens, lost data, permission problems, and other failures.
For example, a test can run the same purchase flow on an iPhone and an Android phone, then verify that payment, confirmation, and order history work on both.
