Nintendo Switch Controller Test

• Use a Pro Controller first if possible. It behaves more like one standard gamepad and is easier to test than a pair of separate Joy-Cons.
• Prefer USB-C for the first pass. It removes Bluetooth uncertainty and gives a cleaner baseline for sticks and buttons.
• Expect Joy-Cons to appear separately. In the browser they are often exposed as two individual gamepads rather than one merged controller.
• Use Chrome or Edge first. They are the safest baseline when you want predictable browser-side controller behavior on desktop.

• You can confirm most standard buttons, stick movement, D-pad style inputs, and whether the controller is actually visible to the browser.
• You may see inconsistent special-button exposure for Home or Capture depending on browser and OS.
• You cannot rely on browser motion testing for gyro and accelerometer behavior because the standard Gamepad API does not surface those controls well.
• Rumble support is inconsistent, so a failed browser haptics result does not automatically mean your Switch controller hardware is bad.

If the problem is stick accuracy rather than basic detection, open the Stick Drift Test. If specific buttons or shoulders seem inconsistent, open the Controller Button Test. If you are mainly checking browser-rumble behavior, compare with the Controller Vibration Test.
