Before:

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'
