The TAP patch sent by Peter on this thread is a very good start.

Not really: The point would not be to test the pager itself (that's for
the people who develop the pager, not for psql), but just to test that the
pager is actually started or not started by psql depending on conditions
(eg pset pager…) and that it does *something* when started. See for
instance the simplistic pager.pl script attached, the output of which
could be tested. Note that PSQL_PAGER is not tested at all either.
Basically "psql" is not tested, which is a pain when developing a non
trivial patch.
