But this is almost exactly what I had in mind when I started DBD::Unify
I somehow have never been able to express those thoughts in words :)
The "problem" is requiring DBI::Test (or whatever) from the DBD in
question, where DBI::Test only depends on DBI. DBI::Test could then do
the DBD-less tests to DBI (again) before being 'use DBI::Test;'d in
DBD's t/ set of files
use DBI::Test; # subclasses Test::More
setup ({ … }); # Things DBI::Test should know to connect, use temp
# tables, and more
dbd_dbi_ok (); # set of sub-tests - can I load DBI
dbd_drv_ok (); # set of sub-tests - can I load DBD
dbd_dbh_ok (); # set of sub-tests - can I connect/disconnect/cache
dbd_sth_ok (); # set of sub-tests - can I do standard things
