A virtual device is a software-based tool with features and functions of physical hardware components. It provides a platform for observing software behavior on different equipment types, such as tablets and phones. Developers use it to test software without interacting with the actual device.
Examples of a Virtual Device
- Android emulator: This tool mimics various Android devices, allowing developers to test apps without the hardware.
- Virtual machines: These machines run several operating systems on one computer, allowing diverse software tests. VMware and VirtualBox are some examples of virtual machines.
- iOS simulator: The iOS simulator is part of Apple’s Xcode and facilitates app testing on virtual iPads and iPhones, ensuring extensive compatibility across Apple products.
- Network emulator: Tools like a comprehensive area network emulator (WANem) imitate network conditions, from slow speeds to data losses, helping engineers ensure that applications can handle various network scenarios.
- Smart home simulators: Platforms like Amazon’s Alexa simulator help to fine-tune software to work effectively in automated home environments.
