You might write a script that generates both the tests and their
list, and have this list included in the  Automake's
own build system do something similar in its script:

   # Create required makefile snippets.
   $PERL ./gen-testsuite-part > t/testsuite-part.tmp
   chmod a-w t/testsuite-part.tmp
   mv -f t/testsuite-part.tmp t/

You might want to peek at the Automake tarball for more details.

You mean at configure runtime?  Like in:

  # in
  all_tests=`cd $srcdir && echo *.test`

  # in
  TESTS = @all_tests@

That would be feasible as well, but only if you use tests with the
'.test' suffix, or some other suffixes declared in TEST_EXTENSIONS
(this will allow Automake to produce correct rules even without
knowing the list of tests at automake runtime).
