Before:

function! LineCallback(job_id, line) abort

endfunction
After:
unlet! g:last_line
unlet! g:lines
unlet! g:data
delfunction LineCallback
delfunction RawCallback
Execute (ALE should handle empty Lists for the lines):
let g:last_line = ale#util#JoinNeovimOutput(1, '', [], 'nl', function('LineCallback'))
AssertEqual [], g:lines
AssertEqual '', g:last_line
Execute (ALE should pass on full lines for NeoVim):
let g:last_line = ale#util#JoinNeovimOutput(1, '', ['x', 'y', ''], 'nl', function('LineCallback'))
AssertEqual ['x', 'y'], g:lines
AssertEqual '', g:last_line
Execute (ALE should pass on a single long line):
let g:last_line = ale#util#JoinNeovimOutput(1, '', ['x'], 'nl', function('LineCallback'))
AssertEqual [], g:lines
AssertEqual 'x', g:last_line
Execute (ALE should handle just a single line of output):
let g:last_line = ale#util#JoinNeovimOutput(1, '', ['x', ''], 'nl', function('LineCallback'))
AssertEqual ['x'], g:lines
AssertEqual '', g:last_line
Execute (ALE should join two incomplete pieces of large lines together):
let g:last_line = ale#util#JoinNeovimOutput(1, 'x', ['y'], 'nl', function('LineCallback'))
AssertEqual [], g:lines
AssertEqual 'xy', g:last_line
Execute (ALE join incomplete lines, and set new ones):

AssertEqual ['xy', 'z'], g:lines
AssertEqual 'a', g:last_line
Execute (ALE join incomplete lines, and set new ones, with two elements):
let g:last_line = ale#util#JoinNeovimOutput(1, 'x', ['y', 'z'], 'nl', function('LineCallback'))
AssertEqual ['xy'], g:lines
AssertEqual 'z', g:last_line
