{
$mapper = function ($setting, $path, $mapReduce) {
$type = 'editable';
if ($setting->hidden == true) {
$type = 'hidden';

* @return void
*/
public function testResultsAreWrappedInMapReduce()
{
$table = TableRegistry::get('articles', ['table' => 'articles']);
$query = new Query($this->connection, $table);
$query->select(['a' => 'id'])->limit(2)->order(['id' => 'ASC']);
$query->mapReduce(function ($v, $k, $mr) {
$mr->emit($v['a']);
});
$query->mapReduce(function ($v, $k, $mr) {
