Measure the signal, not the guess
A focused controller button test for dead inputs, stuck buttons, double presses and inconsistent mappings.
- Face buttons and D-pad directions
- LB/RB bumpers and menu buttons
- Left and right stick clicks
- Pressed state and analog value
Test conditions matter
Use a wired connection when possible, close other controller software, and press a button after the device is connected.
- Press each button once, then hold it briefly.
- Use the event counter to spot missed inputs.
- Compare the browser mapping with the raw snapshot.
