This test has a list of "things" that should be present in the output. This
table is iterated over via pairs(), which means that the output is
non-deterministic and the order of the entries is basically random.
Fix this by using ipairs() to get a deterministic iteration order. This requires
some slight change to the table that is iterated over.
