Physical device testing remains crucial for assessing usability and hardware functionality, despite the rise of real device cloud testing, which offers advantages like cost efficiency, scalability, and remote accessibility. Physical devices provide a realistic testing environment with support for hardware features such as cameras and GPS, but they are costly and geographically restrictive. In contrast, real device cloud testing enables testers to access a wide range of devices and operating systems remotely, offering flexibility and lower costs, although it may lack support for certain hardware features. The choice between the two methods depends on factors such as budget, project requirements, and testing objectives. LambdaTest is highlighted as a platform that facilitates real device cloud testing, providing access to an extensive array of devices and offering tools for efficient test management and debugging.
