Click every button, scroll the wheel and move the mouse over the test pad. Below are checks for double-clicking switches, scroll wheel faults, polling rate, DPI and click speed.
Dashed chips are optional: tilt-wheel left and right only exist on some mice.

A worn switch can turn one click into two. Any press that starts within this window after the same button was released is flagged, because a finger can't click that fast. Click each button normally 20 or so times to check.
Scroll over the test pad. A "slip" is when the wheel briefly goes the wrong way while you scroll steadily, the most common wheel fault.
Move the mouse quickly in circles anywhere on this page for a few seconds. Slow movement sends fewer reports, so the number will read low.
Checks that your computer recognises a double-click, and how fast yours are.
Put the mouse at the start of a ruler. Press Start, move the mouse exactly that distance to the right, then click. For an accurate result, turn off Windows "Enhance pointer precision".
