Before:
  Save g:ale_erlang_syntaxerl_executable

  unlet! g:ale_erlang_syntaxerl_executable
  unlet! b:ale_erlang_syntaxerl_executable

  runtime ale_linters/erlang/syntaxerl.vim


After:
  Restore

  call ale#linter#Reset()


Execute (The executable should be correct):

  let g:ale_erlang_syntaxerl_executable = '/some/other/syntaxerl'
  AssertEqual '/some/other/syntaxerl', ale_linters#erlang#syntaxerl#GetExecutable(bufnr(''))

  let b:ale_erlang_syntaxerl_executable = '/yet/another/syntaxerl'
  AssertEqual '/yet/another/syntaxerl', ale_linters#erlang#syntaxerl#GetExecutable(bufnr(''))
