About Touch Event Tester
Use a touch screen or pointer to inspect event coordinates, pressure, tilt, and contact behavior.
Can a mouse simulate a full multi-touch test?
No. Mouse input can exercise basic pointer behavior, but multiple contacts and stylus pressure require suitable hardware and browser support.
