Before:
  call ale#assert#SetUpLinterTest('haskell', 'hls')

  Save &filetype
  let &filetype = 'haskell'

After:
  call ale#assert#TearDownLinterTest()

Execute(The language string should be correct):
  AssertLSPLanguage 'haskell'

Execute(The default executable should be correct):
  AssertLinter 'haskell-language-server-wrapper',
  \ ale#Escape('haskell-language-server-wrapper') . ' --lsp'

Execute(The project root should be detected correctly):
  AssertLSPProject g:dir

  call ale#test#SetFilename('hls_paths/file.hs')

  AssertLSPProject ale#path#Simplify(g:dir . '/hls_paths')

Execute(The executable should be configurable):
  let g:ale_haskell_hls_executable = 'foobar'

  AssertLinter 'foobar', ale#Escape('foobar') . ' --lsp'

Execute(Should accept configuration settings):
  AssertLSPConfig {}
  let b:ale_haskell_hls_config = {'haskell': {'maxCompletions': 250}}
  AssertLSPConfig {'haskell': {'maxCompletions': 250}}
