Usually one never logs in as root.  You should only escalate as root
when needed, typically via sudo.

There’s probably an error message in test-suite.log in such cases.

‘make check’ uses a different store (see the ‘test-env’ script.)

It may be that $top_builddir/test-tmp/var/XXX/daemon-socket/socket is
created with the wrong user or permissions.

Could you check whether this works:

  ./test-env guile -c '(use-modules (guix store)) (pk (open-connection))'

If it fails, can you prefix that command line with ‘strace -f -o log’,
and post the output of ‘grep daemon-socket log’?

TIA,
