Mouse Tester
The Mouse Tester is an all-in-one browser diagnostic suite designed to test every physical button, scroll wheel increment, and sensor tracking parameter on your computer mouse.
This tool detects left click, right click, middle click, scroll up/down, and extra side buttons (Mouse 4 and Mouse 5) with zero latency using native browser MouseEvents.
By monitoring click events and continuous drag paths, you can easily diagnose microswitch faults such as lost clicks, stuttering drag selections, or loose scroll wheel encoders.
