Before:

After:
  delfunction TestCallback
  call ale#linter#Reset()
  let g:ale_buffer_info = {}
  unlet! b:in_sandbox

Given foobar (Some imaginary filetype):
  foo
  bar
  baz

Execute(ale#util#InSandbox should return 1 when in a sandbox):
  sandbox let b:in_sandbox = ale#util#InSandbox()

  Assert b:in_sandbox, 'ale#util#InSandbox() returned 0 for a sandbox command'

Execute(ALE shouldn't blow up when run from a sandbox):
  AssertEqual 'foobar', &filetype

  sandbox call ale#Queue(0)
  sandbox call ale#Queue(1)
  sandbox call ale#Lint()

Execute(ALE shouldn't blow up if file cleanup happens in a sandbox):
  let g:ale_buffer_info[3] = {
  \ 'temporary_file_list': ['/tmp/foo'],
  \ 'temporary_directory_list': ['/tmp/bar'],
  \}
  sandbox call ale#engine#RemoveManagedFiles(3)

  AssertEqual ['/tmp/foo'], g:ale_buffer_info[3].temporary_file_list
  AssertEqual ['/tmp/bar'], g:ale_buffer_info[3].temporary_directory_list
