Before:
  Save g:ale_buffer_info

  let g:ale_buffer_info = {}

  let g:expected_loclist = [{
  \ 'bufnr': bufnr('%'),
  \ 'lnum': 2,
  \ 'vcol': 0,
  \ 'col': 3,
  \ 'text': 'foo bar',
  \ 'type': 'E',
  \ 'nr': -1,
  \ 'pattern': '',
  \ 'valid': 1,
  \}]

  function! ToggleTestCallback(buffer, output)
    return [{

After:
  Restore

  unlet! g:expected_loclist

  let g:ale_buffer_info = {}
  call ale#linter#Reset()

  delfunction ToggleTestCallback
