When to use these tests
Controller acting up mid-game? Run the gamepad tester and the stick-drift check before buying a replacement. A key that "sometimes" doesn't register shows up immediately on the keyboard tester. Files opening twice on one click is a failing mouse switch — the double click test catches it in ten clicks. And before an interview or meeting, thirty seconds on the mic test and webcam test beats finding out on the call.
