Device Lab

A physical collection of real mobile devices (iOS and Android) kept in one place and used for hands-on testing across hardware, OS versions, and network conditions. Pieter describes his own local device lab of twenty devices connected to several Wi-Fi networks and SIM cards, used to manually monitor app behaviour across multiple real conditions during a live event. Unlike emulators or cloud device farms, a device lab provides direct access to real hardware, which is especially important when testing mobile performance or operating system behaviour that vendors restrict.
