Before:
  Save g:ale_python_auto_pipenv

  let g:ale_python_auto_pipenv = 0

  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'

  GivenCommandOutput ['pylint 2.3.0']

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):
  AssertLinterCwd expand('%:p:h')
  AssertLinter 'pylint', ale#Escape('pylint') . b:command_tail

Execute(Pylint should run with the --from-stdin in new enough versions):
  GivenCommandOutput ['pylint 2.4.0']

  AssertLinterCwd expand('%:p:h')
  AssertLinter 'pylint', ale#Escape('pylint') . b:command_tail[:-3] . '--from-stdin %s'

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

  AssertLinterCwd ''
  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#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#Escape('pylint') . ' --some-option' . b:command_tail

Execute(The pylint callbacks shouldn't detect virtualenv directories where they don't exist):
  call ale#test#SetFilename('python_paths/no_virtualenv/subdir/foo/bar.py')

  AssertLinterCwd ale#path#Simplify(g:dir . '/python_paths/no_virtualenv/subdir')
  AssertLinter 'pylint', ale#Escape('pylint') . b:command_tail

Execute(The pylint callbacks should detect virtualenv directories):
  call ale#test#SetFilename('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'
  \)

  AssertLinterCwd ale#path#Simplify(g:dir . '/python_paths/with_virtualenv/subdir')
  AssertLinter b:executable, ale#Escape(b:executable) . b:command_tail

Execute(You should able able to use the global pylint instead):
  call ale#test#SetFilename('python_paths/with_virtualenv/subdir/foo/bar.py')
  let g:ale_python_pylint_use_global = 1

  AssertLinterCwd ale#path#Simplify(g:dir . '/python_paths/with_virtualenv/subdir')
  AssertLinter 'pylint', ale#Escape('pylint') . b:command_tail

Execute(Setting executable to 'pipenv' appends 'run pylint'):
  let g:ale_python_pylint_executable = 'path/to/pipenv'
  let g:ale_python_pylint_use_global = 1

  AssertLinter 'path/to/pipenv', 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('../python_fixtures/pipenv/whatever.py')

  AssertLinterCwd expand('%:p:h')
  AssertLinter 'pipenv', ale#Escape('pipenv') . ' run pylint'
