What is mouse test?
A mouse test helps you diagnose issues with your mouse buttons, scroll wheel, and sensor. Common mouse problems include double-clicking (when you only clicked once), unresponsive buttons, or scroll jumps.
This tool provides a visual interface to test the Left Click, Right Click, Middle Click (Scroll Wheel Click), and side buttons (Back/Forward). It also logs events so you can see exactly when a 'mousedown' or 'mouseup' event occurs, making it perfect for catching those accidental double-clicks caused by faulty micro-switches.
How to use mouse test
- Step 1: Click each button on your mouse (Left, Right, Middle, Side Buttons).
- Step 2: Ensure the corresponding button on the screen lights up.
- Step 3: Scroll up and down to test the scroll wheel.
- Step 4: Check the event log to ensure one physical click results in exactly one 'Click' event.
