Practical guide

How to perform a complete mouse test

A full mouse check should cover more than the left button. This tester records pointer movement, left/right/middle clicks, wheel activity, double-click behavior, dragging and additional buttons where the browser exposes them.

For a more reliable result

Click each physical button several times and confirm the corresponding visual state changes once per press.
Scroll both directions slowly and quickly to look for missed or reversed wheel events.
Drag across the test area while holding the primary button to check for accidental releases.
Test double-clicks at your normal speed; unusually frequent double activations from a single press can indicate a worn switch.

What this test cannot confirm

Trackpads and iPhone/iPad touchscreens do not expose all traditional mouse controls in the same way. The page provides touch alternatives, but a touchscreen gesture cannot prove that a physical mouse wheel or right switch is working.
