Isn't the http module of nodejs capable of receiving / sending the whole request / response at once?

it fixes the issue
Does it means that this module is not capable of receiving / sending the whole request / response at once and it receives / sends in chunks instead?

Nodejs: Unable to get response body when working with vows and nodejs http module

To fix the issue you can do From what I can see, it looks like Vows doesn't directly invoke the test when this.callback runs. It is delayed by processnextTick. If I had to guess, maybe the 'data' event is being emitted during that time. That means you don't bind your 'data' function until after all the data events have been triggered.
Really though, the issue is that Vows tests are supposed to separate all async logic like this into the topic itself. If you really want to check the chunks in a test, then do it like this.
code :
suite.addBatch({
    'A context': {
        topic: function(){
            var cb = this.callback;
            var req = http.get({
              host: host,
              port: port,
              path: path,
              method: method
            });

            // Aggregate all chunks before running callback
            req.on('response', function(res) {
              var chunks = []
              res.on('data', function(chunk) {
                chunks.push(chunk);
              });
              res.on('end', function() {
                cb(null, res, chunks);
              });
            });

            // Handle connection failures.
            req.on('error', cb);
        },
        "sample test": function(err, res, chunks){
            chunks.forEach(function (chunk, i) {
                console.log('BODY piece ' + i + ': ' + chunk);
            });
            console.log('HEADERS: ' + JSON.stringify(res.headers));
        }
    }
});

Sending xml request to url and receiving xml response back

Sending xml request to url and receiving xml response back

this one helps. I'm trying to send an xml request to a url and the response will also be an xml response. I know how to call a service endpoint from an MVC application but I'm not sure how to call this url and how to read what it will give me back. This is what I have so far. Is this in the right direction? , Here is one way you could do this, which is basically a form post.
code :
var xmlRequest = new XElement("CityStateLookupRequest",
    new XAttribute("USERID", "XXXXXXXXX"),
    new XElement("ZipCode",
        new XAttribute("ID", "0"),
        new XElement("Zip5", "43065")));

HttpWebRequest request = (HttpWebRequest)WebRequest.Create("http://production.shippingapis.com/ShippingAPI.dll");        

// parameters to post - other end expects API and XML parameters
var postData = new List<KeyValuePair<string, string>>();
postData.Add(new KeyValuePair<string, string>("API", "CityStateLookup"));
postData.Add(new KeyValuePair<string, string>("XML", xmlRequest.ToString()));    

// assemble the request content form encoded (reference System.Net.Http)
HttpContent content = new FormUrlEncodedContent(postData);

// indicate what we are posting in the request
request.Method = "POST";
request.ContentType = "application/x-www-form-urlencoded";
request.ContentLength = content.Headers.ContentLength.Value;
content.CopyToAsync(request.GetRequestStream()).Wait();                        

// get response
HttpWebResponse response = (HttpWebResponse)request.GetResponse();

if (response.StatusCode == HttpStatusCode.OK)
{
    // as an xml: deserialise into your own object or parse as you wish
    var responseXml = XDocument.Load(response.GetResponseStream());
    Console.WriteLine(responseXml.ToString());
}

seems to work fine First off, you have not given enough code for people to help you out with, which is probably why you have a down vote already. I'll give you some pointers to get you where you need to go, but if you have further trouble, you need to post all of your code and ask a specific question.
code :
  app.post('/action', function(req, res){
    const status = resultOf.action.doAction(req);
    res.send(status);
  });
