Mouse Test
Check whether your mouse buttons, wheel, double-click, and pointer movement are detected correctly. Use the test area to click, scroll, and move your pointer.
This quick browser tool helps when a mouse button feels inconsistent, the scroll wheel is acting strange, or you want to compare a new mouse.
Button and wheel check
Test clicks, scrolling, double-clicking, and pointer position.
Mouse Inputs
Check the common mouse actions.
The test listens for browser mouse events in the test area, including left click, middle click, right click, wheel movement, double click, and pointer movement.
Click left, middle, and right buttons to confirm each one is detected.
Scroll inside the area to see the wheel counter change.
Move the mouse and watch live x/y coordinates update.
What can a mouse test diagnose?
A browser mouse test can show whether common inputs are reaching the page. It can help identify a button that does not respond, a wheel that sends inconsistent scroll events, or pointer movement that seems jumpy.
Why might results differ by browser?
Browsers and operating systems handle right-click menus, touchpads, high-resolution wheels, and special mouse buttons differently. This test focuses on common inputs that most browsers expose reliably.
Mouse Test FAQ
What can a mouse test diagnose?
A mouse test can help spot button failures, double-click problems, wheel issues, and pointer movement problems reported to the browser.
Why is right-click different in the browser?
Browsers normally open a context menu on right-click, so the test area blocks that menu to detect the button.
Should I compare mouse results on the same device?
Yes. Browser, operating system, mouse driver, wireless connection, and device condition can all change results.
