Mouse Test
Check every mouse button, the scroll wheel, double-clicking, cursor tracking, and dragging. The mouse graphic lights up as you click. Everything runs on your device — nothing is uploaded.
Click the buttons on your real mouse — left, right, and the wheel (middle) — over this area. Right-click is captured here so no menu pops up.

How to use the mouse test
Move your cursor over the page and the cursor (x, y) readout tracks it in real time — jumpy or frozen numbers can indicate a failing sensor or a dirty surface. Click each button on your real mouse: the matching part of the on-screen mouse lights up, the last button field names it, and the clicks counter ticks up. Test the left, right, and middle (scroll-wheel) buttons this way; right-clicks are captured inside the tool so the context menu won't interrupt you.
To check for a worn double-click switch, deliberately double-click and confirm the double-click field reads "detected". A common fault on older mice is the opposite problem — a single click that registers as a double — which you can catch by clicking once, slowly, and watching whether the counter jumps by two. Scroll the wheel up and down to confirm the scroll direction is detected both ways, and press-and-hold inside the drag test box, moving before you release, to confirm dragging holds without dropping mid-motion.
Press Reset counters to start a fresh run. This tool only reads standard mouse and pointer events in your browser and records nothing.
