Mouse Test
Check mouse buttons, hold stability, movement path, and basic wheel events using the browser Pointer Events API.
Tests run locally in your browser. We do not upload keystrokes, pointer paths, or media.
Important
- This reports browser pointer events, not laboratory hardware measurements.

Unexpected large jumps or cancels can indicate focus loss, OS gestures, or driver quirks — not a definitive hardware verdict.
How to use
- Use the test surface for left, middle, right, and side buttons.
- Hold a button to inspect hold duration after release.
- Move inside the surface to draw a path and watch jump metrics.
- Scroll for basic wheel deltas, then open Scroll Wheel Test for deeper diagnostics.
What the result means
- Down/up counters show browser pointer events for each button index.
- Hold duration is the time between pointerdown and pointerup for that button.
- Path distance and max jump are computed from movement samples in the surface.
Limitations
- Button mapping depends on the browser and OS pointer model.
- Touch pads and touch screens produce different event patterns than mice.
- This is browser-observed behavior, not a hardware certification.
Troubleshooting
- Right click opens a menu
- Use the marked test surface — context menu is blocked there.
- Side buttons do nothing
- Some devices remap side buttons in software, so the browser never sees button 3/4.

FAQ
Does a missing event mean the mouse is broken?
Not by itself. Drivers, OS remaps, or browser focus can hide events.
