Abstract: A remote device infrastructure can be used to test and develop applications and websites. A user developer can select a number of remote devices at a remote location and test a programming application from a local machine. The remote devices run the programming application. The user interacts with mirrored displays of the remote devices on the local machine of the user. User inputs are transmitted to a remote device. The user can also enable a multisession mode, where the user can test a programming application on multiple remote devices and observe a display output of each remote device on the local machine of the user. The user can interact with any mirrored display of a remote devices in a multisession and observe a synced output in the other mirrored displays.
