<p><b>BUG ID: 76367</b> <a href="http://bugs.webkit.org/show_bug.cgi?id=76367">Bugzilla bug </a> Add DataTransferItems support for drag-and-drop'ed files and texts</p>

<p id="test" style="background-color:skyblue; padding:3px;"><b>STEPS TO TEST:</b> <br>
1. Open the <a href="resources">$(WebKitRoot)/ManualTests/resources</a> folder in your native file browser.<br>
2. Drag and drop a file into the 'Drop files here' area below.<br>
3. Drag out <a href="#" id="dragout" draggable="true">this link</a> out of the browser window into a different folder in the native file browser).
</p>

<div id="destination" style="min-height:100px; margin: 5px; border: solid 1px black">Drop files here </div>

<p id="success" style="background-color:palegreen; padding:3px;"><b>TEST PASS:</b>
The same file you dropped in the step 2 should be dragged out to the folder in the step 3.  The file should have the same content and the same file name as the dropped file.  (NOTE: this does not work for multiple files yet.)
</p>

<p id="failure" style="background-color:#FF3300; padding:3px;"><b>TEST FAIL:</b>
Nothing happens or a different file from the dropped one (likely a text file with the page title) is dragged out.
</p>
<p id="console"></p>

<script>
function log(text)
{
    var console = document.getElementById('console');
    console.appendChild(document.createTextNode(text));
    console.appendChild(document.createElement('br'));

{
    log((expect == actual ? 'PASS' : 'FAIL') + ': "' + expect + '" == "' + actual + '"');

    for (var i = 0; i < items.length; ++i) {
        test('file', items[i].kind);
        var file = items[i].getAsFile();
        log('Dragged files: ' + file.name);
        log('Dragged file size: ' + file.size);
        files.push(file);

            e.dataTransfer.items.add(files[i]);
        }
    }, false);

    log('Please dragout the link (noted in the step 3) and see if the same file you dropped in in the step 2 is properly drag out.');
