Before:
  Save g:ale_gitcommit_gitlint_executable
  Save g:ale_gitcommit_gitlint_options
  Save g:ale_gitcommit_gitlint_use_global

  unlet! g:ale_gitcommit_gitlint_executable
  unlet! g:ale_gitcommit_gitlint_options
  unlet! g:ale_gitcommit_gitlint_use_global

  runtime ale_linters/gitcommit/gitlint.vim
  call ale#test#SetDirectory('/testplugin/test/command_callback')

  let b:bin_dir = has('win32') ? 'Scripts' : 'bin'
  let b:command_tail = ' lint'

After:
  Restore

  call ale#test#RestoreDirectory()
  call ale#linter#Reset()

  unlet! b:bin_dir
  unlet! b:executable

Execute(The gitlint callbacks should return the correct default values):
  AssertEqual
  \ 'gitlint',
  \ ale_linters#gitcommit#gitlint#GetExecutable(bufnr(''))
  AssertEqual
  \ ale#Escape('gitlint') . b:command_tail,
  \ ale_linters#gitcommit#gitlint#GetCommand(bufnr(''))

Execute(The gitlint executable should be configurable, and escaped properly):
  let g:ale_gitcommit_gitlint_executable = 'executable with spaces'

  AssertEqual
  \ 'executable with spaces',
  \ ale_linters#gitcommit#gitlint#GetExecutable(bufnr(''))
  AssertEqual
  \ ale#Escape('executable with spaces') . b:command_tail,
  \ ale_linters#gitcommit#gitlint#GetCommand(bufnr(''))

Execute(The gitlint command callback should let you set options):
  let g:ale_gitcommit_gitlint_options = '--some-option'

  AssertEqual
  \ ale#Escape('gitlint') . ' --some-option' . b:command_tail,
  \ ale_linters#gitcommit#gitlint#GetCommand(bufnr(''))

Execute(The gitlint callbacks shouldn't detect virtualenv directories where they don't exist):
  silent execute 'file ' . fnameescape(g:dir . '/python_paths/no_virtualenv/subdir/foo/COMMIT_EDITMSG')

  AssertEqual
  \ 'gitlint',
  \ ale_linters#gitcommit#gitlint#GetExecutable(bufnr(''))
  AssertEqual
  \ ale#Escape('gitlint') . b:command_tail,
  \ ale_linters#gitcommit#gitlint#GetCommand(bufnr(''))

Execute(The gitlint callbacks should detect virtualenv directories):
  silent execute 'file ' . fnameescape(g:dir . '/python_paths/with_virtualenv/subdir/foo/COMMIT_EDITMSG')

  let b:executable = ale#path#Simplify(
  \ g:dir . '/python_paths/with_virtualenv/env/' . b:bin_dir . '/gitlint'
  \)

  AssertEqual
  \ b:executable,
  \ ale_linters#gitcommit#gitlint#GetExecutable(bufnr(''))

  AssertEqual
  \ ale#Escape(b:executable) . b:command_tail,
  \ ale_linters#gitcommit#gitlint#GetCommand(bufnr(''))

Execute(You should able able to use the global gitlint instead):
  silent execute 'file ' . fnameescape(g:dir . '/python_paths/with_virtualenv/subdir/foo/COMMIT_EDITMSG')
  let g:ale_gitcommit_gitlint_use_global = 1

  AssertEqual
  \ 'gitlint',
  \ ale_linters#gitcommit#gitlint#GetExecutable(bufnr(''))
  AssertEqual
  \ ale#Escape('gitlint') . b:command_tail,
  \ ale_linters#gitcommit#gitlint#GetCommand(bufnr(''))
