Can you add documentation about the format of test_target?

[horo, 2016/12/09 05:04:11]

Done.

 function executeTest(test_target) {
   if (test_target.length == 0) {
     return Promise.resolve();
   }
   return doFetch(new Request(test_target[0],
                              {credentials: 'same-origin', mode: 'no-cors'}))

         checks.forEach(function(checkFunc) {
             checkFunc.call(this, test_target[0], message);
