  2. Follow the prompt in the test panel and watch the readings update live.
  3. Press Reset to start over with a clean slate.

About the Mouse Test

The Mouse Test tests every mouse button, the scroll wheel and pointer movement in one panel. Finds buttons that no longer register. It runs as plain JavaScript inside the page, which means there is no upload step, no queue and no size limit imposed by a server — the only limit is your own device.

What people use it for

  • Checking a second-hand mouse before the return window closes.
  • Confirming that a button which stopped working is a hardware fault.
  • Testing the side buttons after remapping them.
A button that registers here but does nothing in an application is a software mapping problem, not a broken switch.

Frequently asked questions

Do the side buttons work here?
Only if your mouse sends them as buttons 4 and 5. Many gaming mice ship with them mapped to keyboard shortcuts instead, in which case they arrive as key presses and this test will not see them. Check your mouse software.
Why does the right button not open a menu?
The test cancels the context menu on purpose so it can register the click. Everywhere else on the site the menu behaves normally.
Is there a limit on how often I can use the Mouse Test?
Free, unlimited, and no email address required. You can use it a hundred times a day and nothing changes.
Is my data uploaded anywhere?
No. The Mouse Test runs entirely in your browser using JavaScript. Nothing is transmitted, logged or stored, which you can verify yourself in the Network tab of your browser's developer tools.
What do people use the Mouse Test for most?
The jobs it is built for: checking a second-hand mouse before the return window closes. Confirming that a button which stopped working is a hardware fault. Testing the side buttons after remapping them. It is built for exactly those cases rather than being a general-purpose tool with this bolted on.
What do people usually get wrong here?
A button that registers here but does nothing in an application is a software mapping problem, not a broken switch.
Why does the test start on its own?
No installation, no extension and no driver. The Mouse Test uses the browser's own device APIs and begins as soon as the page loads, so there is nothing to press first. Press Reset at any point to start over with a clean slate.
