That's one aspect of it. We could cache the results of course to amortize the
cost over multiple test-runs but at the end of the day it will add time to
test-runs regardless of what we do.
One thing to consider would be to try and rearrange/refactor the tests to
require a smaller set of keys and certificates. I haven't looked into what
sort of savings that could yield (if any) but if we go the route of
regeneration at test-time we shouldn't leave potential savings on the table.
