Built in the Altom test lab, AltTap is a robot designed to help with and mitigate some of the critical challenges of test automation. It is especially useful in scenarios involving the running of tests on devices of varying screen sizes and resolutions. AltTap’s special power is that of performing automated tests on any type of touchscreen device.
How does it do that exactly? It simulates a human tester by the using of a stylus to perform click actions on a touchscreen. The process is based on an image-recognition algorithm.
