How to interpret this mouse test
A mouse test helps separate basic browser input registration from problems inside a specific game or application. The page listens for pointer, mouse, wheel, context-menu, and double-click events inside the diagnostic surface.
Press each button once and confirm that the expected event appears. Some browsers, operating systems, mouse utilities, or navigation features can intercept auxiliary buttons before a page receives them.
Wheel delta values are browser-visible scroll units, not a standardized physical wheel distance. High-resolution wheels and touchpads may report many small deltas instead of discrete steps.
Use the polling-rate and latency tests for timing analysis. This page focuses on whether the expected controls and event sequence are delivered.
What the browser can and cannot tell you
| Signal | What it represents | How to use it |
|---|---|---|
| Button index | Browser mouse button code | 0 left, 1 middle, 2 right; auxiliary codes can vary |
| buttons bitmask | Currently pressed button set | Useful during drag combinations |
| Wheel delta | Browser scroll delta | Magnitude depends on device and delta mode |
| Movement distance | Accumulated pointer path in CSS pixels | Useful for confirming continuous movement |
| Double-click interval | Time between click events forming dblclick | Affected by operating-system double-click settings |
Build a better troubleshooting habit
Start with a baseline
Run the primary diagnostic before changing settings so you have a comparison point.
Repeat the test
One sample can be misleading. Repeat the check and compare the pattern, not only the best number.
Change one variable
When troubleshooting, change one device, browser, permission, cable, or setting at a time.
Separate browser from hardware
A browser result reflects only the parts of the input or output path that the page can observe.
Document the environment
Keep browser, operating system, device connection, scaling, or permission context with the result.
Use the next diagnostic
Open a related ready page when the result suggests a neighboring part of the device or browser stack.

Free Mouse Test for Buttons, Wheel, Movement, Drag, and Pointer Events: FAQ
Can this test side mouse buttons?+
It can report auxiliary button events that the browser receives, but some systems intercept navigation buttons.
Why is right-click blocked inside the test area?+
The context menu is prevented there so the page can clearly show the right-button event.
Can I test a touchpad?+
Yes. Pointer movement and wheel-like gestures can be observed, although touchpads may behave differently from a mouse.
Does it measure mouse latency?+
Not directly. Use the dedicated mouse latency page for timing-focused measurements.
What does the wheel delta mean?+
It is the scroll amount reported by the browser, which can use pixels, lines, or pages depending on the event mode.
Use the result responsibly
This tool reports what a browser can observe or calculate in the current environment. Device firmware, drivers, operating-system processing, permissions, transport, display refresh, acoustic conditions, and browser implementation can add behavior that this page cannot isolate.
