+1 for this effort, I also think that would be a great addition so show
our current coverage via a service or something like coveralls.io and
possibly the dashboard.  I don't know if coveralls would support the
series branches we create, so I will spend a bit of time looking into
it.

BTW, can you also include information on the current coverage % of code
base?  Last I recall, some of the libraries were quite low (bpf and
bbdev stick in my mind as having very low coverage).
