About Mouse Tester

Runs in your browser

Use the test area to check whether left, right, and middle mouse button events register, whether the wheel produces movement, and whether the browser recognizes a double click. A separate five-second test counts left-button clicks and reports clicks per second (CPS).

The tester responds to standard browser mouse events. It does not detect Back or Forward side buttons, measure switch bounce, or diagnose physical hardware. The double-click indicator only reflects a double-click event recognized by the browser.

Right-click context menus are suppressed inside the test area so the right-button event can be checked. Results depend on the events the browser receives from the connected mouse or pointing device.

How It Works

The test area listens for browser mouse down, mouse up, wheel, and double-click events. It updates the visual left, right, and middle button states, counts wheel movement, and shows a temporary message when a double-click event occurs. The CPS test starts with a left-button click, counts left-button clicks for five seconds, and divides that count by five.

Technical Constraints

•Side buttons are not detected. The double-click indicator reflects the browser's double-click event; it does not measure hardware switch bounce. Right-click context menus are suppressed inside the test area.
