Online Mouse Test
Check every important mouse input in one place. Press buttons, scroll, move and drag inside the test area to see events appear instantly.
Test mouse buttons, scrolling and movement
Use this online mouse tester when a button feels unreliable, the scroll wheel skips, or you want to confirm a new mouse is working correctly. The test listens for browser mouse and pointer events and highlights each control as it is detected.
The main test covers left, right and middle click, common back and forward side buttons, wheel direction, cursor movement, dragging and double-click events. Results stay on your device and reset whenever you choose.
Frequently asked questions
Can this test detect side buttons?+
Most browsers expose common Back and Forward mouse buttons as button 4 and button 5 events. Some vendor-specific extra buttons may not be available to web pages.
Does the test work with wireless mice?+
Yes. The browser sees wireless, Bluetooth and wired mice through the same pointer events.
Why does right click open a menu?+
The test area blocks the browser context menu so the right button can be checked without interruption.
Can a browser prove that a mouse is hardware-perfect?+
No browser test can diagnose every electrical or sensor fault, but it can quickly reveal missing, duplicated or inconsistent input events.
