Online Mouse Test

What this test checks

• Left, middle and right mouse buttons
• Wheel up and down events
• Optional back/forward side buttons when the browser exposes them
• Pointer movement and drag input

How this test works

1. Move the mouse inside the test area.
2. Press left, right and wheel buttons.
3. Scroll up and down, then try dragging.
4. If your mouse has side buttons, press them inside the test area.

If the test does not behave as expected

• If clicks do not appear, try the same mouse in another application or browser.
• Some side buttons may be consumed by the browser or operating system and may not be exposed to the page.
• A missing pointer event does not by itself prove a physical switch failure.
• For wireless mice, also check battery level, receiver connection and Bluetooth status.

Note: Browsers may reserve some system or side-button actions. This test reports events the browser actually exposes and does not measure physical DPI or true USB polling rate.
