Quick answer
What Mouse Test tells you
Check five mouse buttons, pointer movement, drag, wheel direction, double click and pointer type inside one private test area.
- Observed here
- Left, middle, right, back and forward buttons, Pointer coordinates and drag, Scroll direction.
- How to interpret it
- Button indicators, movement and wheel values show input delivered inside this test surface. Events outside it or intercepted by browser navigation may not appear.
- Important limit
- Results reflect events and values exposed by this browser.
- Data handling
- Pointer positions, clicks and touch trails stay in this browser and are not transmitted.
Useful next comparison: Repeat one button, drag or wheel action inside the surface, then compare the same action in another application.
Understanding the result
What a result means
A complete pass includes press and release for the buttons you use, visible pointer movement, wheel direction and a short drag. Back and forward buttons may also trigger browser navigation, so the result should be repeated without relying on one intercepted action.
Confirm the pattern by repeating left, middle, right, back and forward buttons. Results reflect events and values exposed by this browser.
How to use this test
- Read the privacy and compatibility notes.
- Start the test and interact only inside the marked test area.
- Repeat the action several times and compare the live indicators.
- Use the troubleshooting section before deciding that hardware is faulty.
What this test checks
- Left, middle, right, back and forward buttons
- Pointer coordinates and drag
- Scroll direction
- Pointer type and pressure when supported
What this test cannot check
Results reflect events and values exposed by this browser.
This test does not certify hardware or replace professional inspection.
Right-click is suppressed only inside the test pad.
Coordinates are not stored or transmitted.
Common problems and troubleshooting
Keep every action inside the test area, then compare the same button in another application. For missing side buttons, review vendor mapping software; for erratic motion, compare a different surface, port, receiver position or wired mode.
- Repeat the same observation. Focus the test surface and repeat “Left, middle, right, back and forward buttons” three times under the same conditions.
- Change one condition. Compare “Pointer coordinates and drag” after changing only the relevant port, connection, browser setting or application.
- Rule out focus or interception. Close overlays and reserved shortcuts, keep the page visible and confirm that the live indicator changes during the action.
- Keep the result within its limit. Results reflect events and values exposed by this browser.
If the same pattern remains across relevant applications and connections, give the manufacturer or a qualified technician the repeatable observations instead of a guessed fault label.
Browser compatibility
Pointer and wheel events are broadly supported, but button numbering, pressure and navigation handling vary by device and browser. Trackpads can report smooth deltas that should not be interpreted as physical wheel notches.

Frequently asked questions
Is this Mouse Test free?
Yes. The test works without an account, download or payment.
Is my test data uploaded?
Pointer positions, clicks and touch trails stay in this browser and are not transmitted.
Does this result prove my hardware is faulty?
No. It shows what the browser can observe. Repeat the test, compare another browser or device, and seek qualified support when the result matters.
