Arbitrary number of tests with GNU Autotest

Question

I'm working on a project using Autotools and want to integrate Autotest for all the functional tests. Each test has to be run like this:

./program <test file>

My $(top_srcdir)/tests directory looks like this:

% ls -1p
    good/ # Directory containing files expected to pass.
    bad/  # Directory containing files expected to fail.
    testsuite.at # The test suite.
    # Makefile.am, atlocal.in, etc...

Both good/ and bad/ contains an average of 150 test files. I would like to avoid typing each test by hand, and I can't seem to find how to reproduce something like what's next with m4/Autotest macros:

for i in $(ls good/) ; do
    AT_SETUP([$i])
    AT_CHECK([./program $i])
    AT_CLEANUP
done

The real-world case which is the closest to mine (and that I found) lies in the test suite of the m4 project which generates a generated.at file using its own documentation.
Should I follow this way and generate good.at and bad.at before invoking autom4te on testsuite.at, or is there a way using m4/Autotest macros ?

Thanks!
