Examples for tests?  No idea.  The gnulib repository contains oodles of
tests.  Maybe looking at them helps you write them?

A minor lingo nit, "Autotest" is a different test suite driver, it comes
with Autoconf and is purely m4 and shell based:

What you're looking at is the simple test driver from Automake.
Incidentally, the Libtool package tests a library (libltdl) among other
things, and uses both Autotest and the simple driver from Automake.

If I were writing tests for a library, I'd be writing a bunch of small
programs as unit tests of library specifics, and maybe a larger one that
tries out more complex operations, and some shell scripts calling that
larger program with different options:

unittests = unit1 unit2 ...
scripttests = script1 script2 ...
check_PROGRAMS = $(unittests) large-prog ...
check_SCRIPTS = $(scripttests) helper-script ...
TESTS = $(unittests) $(scripttests)
LDADD = libsk.a

You should check out parallel-tests from Automake 1.11:
