Before:
  Save b:ale_groovy_npmgroovylint_fix_options

  call ale#assert#SetUpFixerTest('groovy', 'npm-groovy-lint')

After:
  Restore

  call ale#assert#TearDownFixerTest()

Execute(The callback should return the correct default values):
  AssertFixer {
  \  'read_temporary_file': 1,
  \  'command': ale#Escape('npm-groovy-lint') . ' --fix %t',
  \ }

Execute(The callback should include custom options):
  let b:ale_groovy_npmgroovylint_fix_options = '--format'

  AssertFixer {
  \  'read_temporary_file': 1,
  \  'command': ale#Escape('npm-groovy-lint') . ' --format %t',
  \ }
