Mouse Tester

How to use the mouse tester

1. Click each button inside the test area, including the wheel.
2. Scroll up and down, and move the pointer around.
3. For a double-click fault, click slowly ten times and watch the count.

About this tool

Every button, the scroll wheel and pointer position are reported as you use them. Right-click is captured inside the test area rather than opening the context menu, which is the only way to test it in a browser.

The fault this is most often used to find is double-clicking: a worn micro-switch bounces, so one deliberate press registers as two clicks. To check for it, click slowly and deliberately about ten times and watch whether the count goes up by more than one. It is a mechanical failure and gets worse over time — it does not fix itself.

Side buttons only appear if your mouse sends them as mouse buttons. Many gaming mice are configured to send keyboard shortcuts instead, in which case they will not register here even though they work perfectly.

Common uses

• Confirming a double-click fault before replacing a mouse.
• Checking whether the scroll wheel skips or jumps.
• Testing side buttons on a new mouse.

Frequently asked questions

How do I test for the double-click problem?

Click slowly and deliberately about ten times. If the click count rises by more than one per press, the switch is bouncing — a mechanical fault that only worsens.

Why don't my side buttons register?

Many mice send keyboard shortcuts rather than mouse buttons for those. The browser then sees a keystroke, not a button, so nothing shows here.

Why is right-click not opening the menu?

That is deliberate inside the test area, so the right button can be tested. Everywhere else on the page it behaves normally.
