Pointer lock is tricky to automate tests for. Consider some examples: - Upon lock, no pointer should be visible. - A user gesture is required to lock when not in fullscreen. - Transitioning to fullscreen and pointer lock then exiting fullscreen should maintain pointer lock. (User gesture required to enter fullscreen) - While locked, moving the mouse indefinitely in any direction must continue to provide non zero movementX/Y values.
I'm considering starting some pointer lock tests with testharness.js. The only solution I see is to provide instructions in many tests for manual actions and observations. I appreciate any best practice suggestions, or pointers to other specifications with similar challenges. So far I see geolocation tests provide manual instructions.
