Tool guide

About Mouse Tester

Check whether mouse buttons, wheel movement, and pointer events reach the browser test area. It helps with a simple functional check but cannot inspect hardware switches directly.

How to use this tool

  1. 1Move the pointer into the test area and click each mouse button.
  2. 2Scroll the wheel and test any additional buttons the page can detect.
  3. 3Review the event feedback and compare with another app if a control seems unresponsive.

How the tool works

The page listens for pointer, mouse-button, and wheel events delivered by the browser and updates its status. Browser context menus, OS gestures, and device drivers can intercept actions before the page sees them.

Worked real-world example

A middle-button click should create a browser event when the page has focus and the button is available.

Common scenarios and use cases

Check basic mouse input after setup or compare whether a button works in the browser.

Important details and limitations

This is not a latency, sensor-precision, or hardware durability test. Browser settings and custom button mappings can change the events reported.

Check the output unit as well as the number. If the result will be reused in another calculation, retain full precision where possible and round only at the end. For measurements governed by a technical specification, use the standard and tolerance required by that document.

Frequently asked questions

Why is a side button not detected?

The browser may not expose it or the device software may map it differently.

Does the test measure accuracy?

No. It checks event response, not sensor precision.

Can I test scrolling?

Yes, move the pointer over the test area and use the wheel.
