Before:
  call ale#assert#SetUpLinterTest('python', 'pylint')

  let b:bin_dir = has('win32') ? 'Scripts' : 'bin'
  let b:command_tail = ' --output-format text --msg-template="{path}:{line}:{column}: {msg_id} ({symbol}) {msg}" --reports n %s'

After:
  unlet! b:bin_dir
  unlet! b:executable
  unlet! b:command_tail

  call ale#assert#TearDownLinterTest()

Execute(The pylint callbacks should return the correct default values):
  AssertLinter 'pylint',
  \ ale#path#BufferCdString(bufnr(''))
  \   . ale#Escape('pylint') . ' ' . b:command_tail

Execute(The option for disabling changing directories should work):
  let g:ale_python_pylint_change_directory = 0

  AssertLinter 'pylint', ale#Escape('pylint') . ' ' . b:command_tail

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

  AssertLinter 'executable with spaces',
  \ ale#path#BufferCdString(bufnr(''))
  \   . ale#Escape('executable with spaces') . ' ' . b:command_tail

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

  AssertLinter 'pylint',
  \ ale#path#BufferCdString(bufnr(''))
  \   . ale#Escape('pylint') . ' --some-option' . b:command_tail

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

  AssertLinter 'pylint',
  \ ale#path#BufferCdString(bufnr(''))
  \   . ale#Escape('pylint') . ' ' . b:command_tail

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

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

  AssertLinter b:executable,
  \ ale#path#BufferCdString(bufnr(''))
  \   . ale#Escape(b:executable) . ' ' . b:command_tail

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

  AssertLinter 'pylint',
  \ ale#path#BufferCdString(bufnr(''))
  \   . ale#Escape('pylint') . ' ' . b:command_tail

Execute(Setting executable to 'pipenv' appends 'run pylint'):
  let g:ale_python_pylint_executable = 'path/to/pipenv'

  AssertLinter 'path/to/pipenv',
  \ ale#path#BufferCdString(bufnr(''))
  \   . ale#Escape('path/to/pipenv') . ' run pylint'
  \   . '  --output-format text --msg-template="{path}:{line}:{column}: {msg_id} ({symbol}) {msg}" --reports n %s'

Execute(Pipenv is detected when python_pylint_auto_pipenv is set):
  let g:ale_python_pylint_auto_pipenv = 1
  call ale#test#SetFilename('/testplugin/test/python_fixtures/pipenv/whatever.py')

  AssertLinter 'pipenv',
  \ ale#path#BufferCdString(bufnr(''))
  \   . ale#Escape('pipenv') . ' run pylint'
  \   . '  --output-format text --msg-template="{path}:{line}:{column}: {msg_id} ({symbol}) {msg}" --reports n %s'
