useFakeXMLHttpRequest never gives readyState == 4

[Seb]

Hi All,

I've been puzzled for the whole day about this !

I'm trying to test Ajax using XMLHttpRequest (I'm not crazy, just debbuging why it is not working for REST.js) and readyState (in onreadystatechange) is never set to 4, and therefore it hangs until when it times out.

Any ideas ?

Thanks !

    beforeEach(function() {
      xhr = sinon.useFakeXMLHttpRequest();
      requests = [];
      xhr.onCreate = function (req) { requests.push(req); };
    });

    afterEach(function() {
      xhr.restore();

    });

      it('FAKE SERVER', function(done) {
        var oReq = new XMLHttpRequest();
        oReq.onreadystatechange = function() {
          console.log('FAKE SERVER >> ' + oReq.readyState + " -> " + oReq.status + " -> " + JSON.stringify(oReq));
          if (oReq.readyState==4) done();
        }
        try {
          oReq.open('GET', '/api/testmodel/1');
          oReq.send();
        }
        catch (ex) {
          done();

          console.log('FAKE SERVER >> ' + ex);
        }


        console.log('FAKE SERVER >> -- <<');
      });

LOG: 'FAKE SERVER >> 1 -> 0 -> {"readyState":1,"requestHeaders":{},"requestBody":null,"status":0,"statusText":"","upload":{"eventListeners":{"progress":[],"load":[],"abort":[],"error":[]}},"responseType":"","response":"","withCredentials":false,"eventListeners":{"loadend":[null],"abort":[null],"load":[null],"loadstart":[null]},"method":"GET","url":"/api/testmodel/1","async":true,"responseText":null,"responseXML":null,"sendFlag":false}'

Was there never a response to this?   I am running into the same issue and don't see any resolutions online...  Looking at the fakeServer code, I don't see a way to set the readyState without editing Sinon's code.
