Before:
  Save g:ale_command_wrapper

  runtime autoload/ale/lsp.vim

  let g:ale_command_wrapper = ''

  let g:args = []

  " Mock the StartProgram function so we can just capture the arguments.
  function! ale#lsp#StartProgram(...) abort
    let g:args = a:000[1:]
  endfunction

After:
  Restore

  unlet! g:args

  runtime autoload/ale/lsp.vim

Execute(Command formatting should be applied correctly for LSP linters):
  call ale#lsp_linter#StartLSP(
  \ bufnr(''),

  \   'language_callback': {-> 'x'},
  \   'project_root_callback': {-> '/foo/bar'},

  \   'executable': has('win32') ? 'cmd': 'true',
  \   'command': '%e --foo',
  \ },
  \ {-> 0}
  \)

  if has('win32')
    AssertEqual
    \ ['cmd', 'cmd /s/c "cmd --foo"'],
    \ g:args
  else
