Before:
  call ale#assert#SetUpFixerTest('markdown', 'markdownlint-cli2')

After:
  call ale#assert#TearDownFixerTest()

Execute(The default command should use a temporary file):
  AssertFixer {
  \ 'command': ale#Escape('markdownlint-cli2') . ' --fix %t',
  \ 'read_temporary_file': 1,
  \}

Execute(The executable should be configurable):
  let g:ale_markdownlint_cli2_executable = 'custom_markdownlint_cli2'

  AssertFixer {
  \ 'command': ale#Escape('custom_markdownlint_cli2') . ' --fix %t',
  \ 'read_temporary_file': 1,
  \}

Execute(Custom options should not remove the required --fix option):
  let g:ale_markdownlint_cli2_executable = 'markdownlint-cli2'
  let g:ale_markdownlint_cli2_options = '--no-globs'

  AssertFixer {
  \ 'command': ale#Escape('markdownlint-cli2') . ' --fix --no-globs %t',
