I think it should be possible to write web-platform-tests for this kind
of thing now, using the testdriver API and in particular the actions
support see e.g. , 
If this still doesn't meet your use case please let me know because we

cross-browser; as you well know UI events have been an interop nightmare
in the past and we can't afford to let that situation continue into the
future for new devices and APIs.
