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

There=E2=80=99s probably an error message in test-suite.log in such cases.

=E2=80=98make check=E2=80=99 uses a different store (see the =E2=80=98test-=
env=E2=80=99 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 =E2=80=98strace -f -o lo=
g=E2=80=99,
and post the output of =E2=80=98grep daemon-socket log=E2=80=99?

TIA,
Ludo=E2=80=99.
