How to use
- Open the tool and move into the highlighted mouse test area.
- Click left, middle, and right in any order you need to validate.
- Scroll up and down inside the test zone so wheel events register.
- Watch live press states and per-button / scroll counters.
- Press Reset to clear counts before another pass or when switching mice or USB ports.
FAQ
Can I test all mouse buttons here?
Yes. The tool tracks left, middle, right, and scroll wheel activity.
Why does right-click menu not appear inside the test?
Context menu is suppressed in the test zone so right-click input can be counted cleanly.
Introduction
Mouse Button Test shows whether each mouse button and the scroll wheel produce the expected events in your browser — no drivers required.
Purpose
- Confirm that left, middle, right, and scroll inputs reach the page correctly.
- Quickly compare two devices, or the same device before/after driver or USB port changes.
Key Features
- Visual feedback for left, middle, right, and scroll input on a single page.
- Per-action counters so you can confirm each physical input maps to the browser.
- Reset clears state for a clean re-test.
Common Use Cases
- QA after buying a new mouse or switching USB / Bluetooth receiver.
- Verifying remapped buttons or gaming mouse software profiles.
- Teaching which physical button maps to
button === 2vs1in web terms.
Best Practices
- Click inside the test zone so right-clicks are captured without the normal context menu where the tool suppresses it.
- Test on a plain surface and avoid bumping the cable mid-check.
- If a key sticks in software, unplug/re-pair before assuming hardware failure.
Comparison metrics
- Per-button and scroll counts: Repeat the same actions on another mouse or port and compare totals; each intentional action should increment once without stuck “down” states.
- There is no single numeric quality score — stability is judged from clean one-to-one press and release behavior.
