Looks fine like this, I don't think there's any actual portability
concern (as with some wrappers), but FWIW you can do this more briefly
with the test framework as:

    test_line_count = 0 actual

Although I wonder in this case whether you don't actually mean:

    [...]>actual &&
    ! test -s actual

I.e. isn't the test that there should be no output, not that there
shouldn't be a \n there? Or alternatively:

     test $(cat actual | wc -c) -eq 0
