tests/example/: Print status messages

Running the tests sadly takes much to long. Since I don't have a good idea what
to do about this (I'd like to run all tests in a single Lua process, but that
doesn't seem to be possible easily), instead let's just make it more explicit
what is being done. This commit prints a message for each test that is being
run.
