Is your feature request related to a problem? Please describe.

Without a Braille device, Braille gestures cannot be tested using NVDA.
This is because of how inputCore.registerGestureSource works.

Describe the solution you'd like

Braille gestures are configured on a braille device level, and as such, emulating input gestures is not possible with keyboard commands.
To test braille consistently, it would be helpful to have a braille display driver to emulate braille keys using the Braille viewer.

Describe alternatives you've considered

Adding the ability to map Braille input gestures to keyboard commands.
