Description

I see this on Windows. This is happening when test-framework checks whether Medic config exists and calls callback twice when there is no config available (default case when you use test framework locally):
1. Inside onload
2. Inside exception catch block

exports.load = function (callback) {
  var xhr = new XMLHttpRequest();
  xhr.open("GET", "../medic.json", true);
  xhr.onload = function() {
    if (xhr.readyState == 4 && xhr.status == 200) {
      var cfg = JSON.parse(xhr.responseText);
      exports.logurl = cfg.logurl;
      exports.enabled = true;
      console.log('Loaded Medic Config: logurl=' + exports.logurl);
    }
    callback();
  }
  xhr.onerror = function() {
   callback();
  }

  try {
    xhr.send(null);
  }
  catch(ex) {
    // some platforms throw on a file not found
    console.log('Did not find medic config file');
    setTimeout(function(){
        callback();
    },0);
  }
}
