Sure. Here is a tree for a minimal project (see also the attached archive):

# ./configure.ac
AC_INIT([myproject], [0.1], [[email protected]])
AM_INIT_AUTOMAKE([foreign dejagnu])
AC_CONFIG_FILES(Makefile)
AC_OUTPUT
###

# ./Makefile.am
TESTS = ok

ok:
    $(AM_V_GEN)echo "#!/bin/sh" >$@
    @chmod a+x $@

CLEANFILES = ok

EXTRA_DIST = testsuite/config/unix.exp testsuite/lib/myproject.exp
testsuite/myproject.tests/myproject.exp
###

# ./testsuite/myproject.tests/myproject.exp
pass "trivial test"
###

# ./testsuite/config/unix.exp
# empty file
###

# ./testsuite/lib/myproject.exp
# empty file
###

You should then be able to run:
$ autoreconf -i
$ ./configure [--enable-silent]
$ make check-DEJAGNU
$ make check-TESTS

As you see, I added two test cases, one using the Dejagnu test driver
(that produces the noise) and one that uses the modern Automake
parallel test driver (which does not produce any noise, regardless of
the setting of the silent flag).

I hope you find this helpful.

Thanks,

Marc
