Can there be a test_line_count of the output of ls at the beginning, so
that we do not have to look at the previous test to indeed see that the
5 is greater than before?
Also add a test to check what happens when we have 3 packs below the
batch size, but taking 2 of them together is sufficient to exceed the
batch size.

Same comment as above.
