I need to read data from FormData? I try to read something like someFormatData[valueName] but it not working.
options[fileId] or options[file] does not work. Also I try options.fileId same result:

function upload(file, fileId, callback) {

    var formData = new FormData();

    formData.append(file, file);

    formData.append(fileID, fileId);



    $.ajax({

        url: '/url',

        type: 'POST',

        data: formData,

        processData: false,

        contentType: false,

        success: function(response) {

            callback(response);

        }

    });

}





asyncTest(test upload chunk, function() {

    var blob = new Blob([Hello world!], { type: text/plain }),        

        options = null,

        fileID =someFileID,

        response;



    jQuery.ajax = function(param) {

        options = param;   // THIS is FormData object 

        // how to read fileId and file from here

    };



    upload(blob, fileID, function (data) {

        response = data;  

    });



    options.success({

        someProp: 'responseFromServer'

    });



    setTimeout(function() {

        QUnit.equal(options, dataTosend, parameters is OK);

        QUnit.equal(response[someProp], responseFromServer, Response ok);

        start();

    },1000);

});
