A GUI of a testing module 302, in certain embodiments, may display a scene tree or other listing of user interface elements to a user (e.g., which may be received from a device 102, which a user may select to view additional data, which a user may select to automatically include in a script, or the like). In certain embodiments, instead of and/or in addition to executing a script, a testing module 302 may provide an interface allowing a user to provide input (e.g., one or more simulated user input events) and may mirror the provided input (e.g., touch input events) on one or more testing devices 102 (e.g., which may actually receive the provided input in independently executing applications on the different devices 102, as touch input events or the like, instead of simply mirroring a display). A testing module 302 may simulate one or more touch input events or other user input events (e.g., mirrored, based on a script, or the like) on different devices 102 by screen location (e.g., x- and y-coordinates or the like), by user interface element (e.g., a label or other identifier for a node in a hierarchical screen tree representing a displayed object so that the event is interpreted similarly even for different screen orientations, different versions of an application, or the like), and/or using a different input location identifier.
