How to wait for request to finish in Jmeter - jmeter

Question

I am currently new to Jmeter, and trying to create a Jmeter script to test how long a request takes to process and complete.
a) Authenticate using Token - Complete
b) Post Request - Complete - Returns 200
c) Get Request - Partially Completed
C: I am Trying to get be able to monitor this request to find out when its either completed failed etc.
I have created the Http Request Sample with a Get Request
I am able to get the Request 200 but it doesn't wait for completion
So running this in a console app, it waits for a certain time checking for status....
Is there a way to possibly write a code similar to the C# code in bean shell or groovy to wait. I was reading about while controller as well...
var result = WaitForBuildToComplete(dest, requestData, token, timeout);
static string GetStatus(string path, Token token)
{
var httpWebRequest = (HttpWebRequest)WebRequest.Create(path);
httpWebRequest.ContentType = "application/json";
httpWebRequest.Method = "GET";
AddToken(token, httpWebRequest);
WebResponse response = httpWebRequest.GetResponse();
string responseFromServer = "";
using (Stream dataStream = response.GetResponseStream())
{
StreamReader reader = new StreamReader(dataStream);
responseFromServer = reader.ReadToEnd();
}
// Close the response.
response.Close();
return responseFromServer;
}
static int WaitForBuildToComplete(string dest, RequestData requestData, Token token, int
timeout)
{
if (timeout <= 0) return 0;
var path = $"{ConfigurationManager.AppSettings[dest]}/policy?id={requestData.id}";
var startTime = DateTime.Now;
do
{
var status = GetStatus(path, token);
var msg = JsonConvert.DeserializeObject<string>(status);
var requestStatus = JsonConvert.DeserializeObject<RequestStatus>(msg);
if (!string.IsNullOrEmpty(requestStatus.DllUrl))
{
Console.WriteLine($"\nResult dll at: {requestStatus.DllUrl}");
return 0;
}
if (requestStatus.Status.ToUpper() == "FAILED")
{
Console.WriteLine($"\nFAILED");
Console.WriteLine(requestStatus.Message);
return -1;
}
if (requestStatus.Status.ToUpper() == "FAILED_DATA_ERROR")
{
Console.WriteLine($"\nFAILED_DATA_ERROR");
Console.WriteLine(requestStatus.Message);
return -1;
}
if (requestStatus.Status.ToUpper() == "NOT_NEEDED")
{
Console.WriteLine($"\nNOT_NEEDED");
Console.WriteLine(requestStatus.Message);
return -1;
}
Console.Write(".");
System.Threading.Thread.Sleep(1000);
} while ((DateTime.Now - startTime).TotalSeconds < timeout);
Console.WriteLine("Time out waiting for dll.");
return -1;
}
I started by looking at JSR223 Sampler but wanted to see if there is a better and easier way to accomplish this.
List<String> sendRequest(String url, String method, Map<String,Object> body) {
RequestConfig requestConfig = RequestConfig.custom()
.setConnectTimeout(2000)
.setSocketTimeout(3000)
.build();
StringEntity entity = new StringEntity(new Gson().toJson(body), "UTF-8");
HttpUriRequest request = RequestBuilder.create(method)
.setConfig(requestConfig)
.setUri(url)
.setHeader(HttpHeaders.CONTENT_TYPE, "application/json;charset=UTF-8")
.setEntity(entity)
.build();
String req = "REQUEST:" + "\n" + request.getRequestLine() + "\n" + "Headers: " +
request.getAllHeaders() + "\n" + EntityUtils.toString(entity) + "\n";
HttpClientBuilder.create().build().withCloseable {httpClient ->
httpClient.execute(request).withCloseable {response ->
String res = "RESPONSE:" + "\n" + response.getStatusLine() + "\n" + "Headers: " +
response.getAllHeaders() + "\n" +
(response.getEntity() != null ? EntityUtils.toString(response.getEntity()) : "") + "\n";
System.out.println(req + "\n" + res );
return Arrays.asList(req, res);
}
}
}
List sendGet(String url, Map<String,String> body) {
RequestConfig requestConfig = RequestConfig.custom()
.setConnectTimeout(2000)
.setSocketTimeout(3000)
.build();
RequestBuilder requestBuilder = RequestBuilder.get()
.setConfig(requestConfig)
.setUri(url)
.setHeader(HttpHeaders.CONTENT_TYPE, "application/json;charset=UTF-8");
body.forEach({key, value -> requestBuilder.addParameter(key, value)});
HttpUriRequest request = requestBuilder.build();
String req = "REQUEST:" + "\n" + request.getRequestLine() + "\n" + "Headers: " +
request.getAllHeaders() + "\n";
HttpClientBuilder.create().build().withCloseable {httpClient ->
httpClient.execute(request).withCloseable {response ->
String res = "RESPONSE:" + "\n" + response.getStatusLine() + "\n" + "Headers: " +
response.getAllHeaders() + "\n" +
(response.getEntity() != null ? EntityUtils.toString(response.getEntity()) : "") + "\n";
System.out.println(req + "\n" + res );
return Arrays.asList(req, res);
}
}
}

The approach which is normally used in JMeter is placing your request under the While Controller which will be checking the Status value which in its turn can be fetched from the response using a suitable Post-Processor so the request will be retried unless the "Status" changes to some value which you expect (or times out)
If you place the whole construction under the Transaction Controller you will get the whole time for the status to change.
