"configure --enable-coverage"; install the resulting tree; then run
whatever tests you want, then "make coverage". That's enough to get the
HTML reports.

Well, I don't disagree that we could do with some tests that are run
additionally to the ones we currently have, but some basic stuff that
takes almost no time to run would be adequate to have in the basic
regression tests. The one I'm thinking is something like generate a
VALUES of all the supported object types, then running
"pg_get_object_address" on them to make sure we support all object types
(or at least that we're aware which object types are not supported.)
For instance, Petr Jelinek's patch to add the TABLESAMPLE clause adds a
new object type which needs support in get_object_address, but I'm not
sure it's added to the stuff in the object_address test. It's a very
easy omission to make.
