Before:
  Save b:ale_groovy_npmgroovylint_options

  call ale#assert#SetUpLinterTest('groovy', 'npmgroovylint')
  call ale#test#SetFilename('test.groovy')

After:
  call ale#assert#TearDownLinterTest()

Execute(The default npm-groovy-lint command should be correct):
  AssertLinter 'npm-groovy-lint',
  \ ale#Escape('npm-groovy-lint') . ' --failon none --output json --loglevel warning %t'

Execute(Default options should be configurable):
  let b:ale_groovy_npmgroovylint_options = '--loglevel info'

  AssertLinter 'npm-groovy-lint',
  \ ale#Escape('npm-groovy-lint') . ' --failon none --output json --loglevel info %t'
