This because fs.rename() can't move file between two different disks
Other renameSync doesn't create new folder, so you should ensure the tmp/ is must exist. You need creat tmp folder in your sourcecode file folder,then set the uploadDir like so:

var form = new formidable.IncomingForm();
  form.uploadDir = "tmp";
  console.log("about to parse");
  form.parse(request, function(error, fields, files) {
    console.log(files.upload.path);
    try{
        fs.renameSync(files.upload.path, "tmp/test.jpg");
    }catch(e){
        console.log(e);
    }
    response.writeHead(200, {"Content-Type": "text/html"});
    response.write("received image:<br/>");
    response.write("<img src='/show' />");
    response.end();
  });
