I am using the HTTP request sampler, In which I have used Post Method.
When I Execute the request, it executes the another HTTP request from another thread.
I want to extract the data from that thread because that HTTP request contains the transaction id and I want to use that transaction id in other threads.
The said transaction id is only showing in the pop up message.
Kindly help me.
Solution for the first problem retrieving data from request URL i.e.transaction id using a postprocesser, you can refer the following thread,
Post processer for extracting a value from the URL in the request method.
Solution for the second problem passing the variable from one thread to another,
You need to add a beanshell assertion and set it a property variable like ${__setProperty(transaction_id, ${transID})}
In the second thread group add a preprocesser and accept the property variable.
String tid= props.get("transaction_id");
vars.put("TID",tid);

Thread2:
JMeter can only extract data from response body, message, code, headers, or URL.
If you send the request which triggers another request and the data you're looking for is not in the 1st request response scope - unfortunately you won't be able to get it.
The only option I can think of is using WebDriver Sampler which provider JMeter integration with Selenium browser automation framework so you would be able to execute the request and get the data from the popup using real browser.
WebDriver Sampler can be installed using JMeter Plugins Manager

I have a login form that has form method set to POST, form-action set to a servlet, and an OnSubmit function to check the field data.I want to performance test a file download funcitonality that lies behind this login form. To acheive this i am running a parallel sampler to login and then download the file.
The first sampler is for the login and the second one is to dowload the file.
In the first sampler, I want to POST data on this form using JMeter's HTTP Reqest Sampler.
I have inspected the form and created a sampler with three parameters, the username, the password and one more non-discloseable field. I have set the path to the servlet since it is the one handling the requests for the form.
The post request doesn't do anything in this case.
What should i do or check or modify to make sure that the POST request is hitting the correct endpoint and that it actually submits the form data.
You need the samplers to be sequential, I think if you attempt to download the file without prior logging in - the request will fail somewhere somehow.
If it is not sufficient and you would like to add an extra level of checks, i.e. test that the endpoint returns anticipated response code or has certain text you could add Response Assertion as a child of the request and add pass/fail criteria there.
If you don't know how to properly build login and download requests, the easiest way is just recording them using HTTP(S) Test Script Recorder, JMeter will capture the requests and generate relevant HTTP Request samplers and HTTP Header Managers
Sorry for the title being a little unclear, but I will do my best to explain what I am trying to achieve.
Send a xml request to the following URL `http://122.52.45.18:16000/foo/v1/TestData/ using POST.
This returns a HTTP/1.1 200 OK and a unique location header so something like `c4299g99-986f-53d6-c635-171b312333ef (location header is unique each time)
This is then added to the end of the request URL to retrieve the response(which is also an xml) via a GET. `http://122.52.45.18:16000/foo/v1/TestData/c4299g99-986f-53d6-c635-171b312333ef
In Jmeter, I have been trying to use the
WebSocket request-response Sampler plugin to get it working but don't believe this is the right plugin to use.
What can I do in Jmeter to create a test for this?
You can use HTTP Request sampler. Add this sampler to Thread Group, choose it and change Method to POST (by Default it's GET) then select Body Data tab to paste the XML that you want to send.
After that you will be able to extract and reuse the value from request with Regular Expression Extractor (just choose Field to check - Response Headers on that screen) to send it to the next one.
Also you can simply record a scenario with your browser and JMeter proxy.
I am trying to simulate a parallel ajax requests using a JSR223 sampler, as mentioned here https://www.blazemeter.com/blog/how-load-test-ajaxxhr-enabled-sites-jmeter
But for my set of requests ,I am getting an error,Invalid API/Auth Key
I assume it is is becuase the authentication cookie is not being passed ,I tried to grab the cookie from the previous sampler using
HTTPSamplerProxy previousSampler = ctx.getPreviousSampler();
CookieManager cookieManager = previousSampler.getCookieManager();
HTTPSampleResult previousResult = (HTTPSampleResult)ctx.getPreviousResult();
log.info("Cookie Count is : "+ cookieManager.getCookieCount());
But I get the error
Cannot invoke method getCookieCount() on null object
,I do have the cookie manager enabled in my test plan.
Any help on what I am doing wrong would be great .
The error you're getting means that there is no HTTP Cookie Manager associated with the sampler. You need to add it to your Test Plan and your code should start working as expected.
Be aware that as of now there is a much easier way to implement AJAX requests without having to do any coding, there is Parallel Controller which can be used to mimic AJAX calls by running its children in parallel. Just add it to your Test Plan and move HTTP Request samplers which represent AJAX calls under it. See How to Use the Parallel Controller in JMeter for more details if needed.
I'm still pretty new to jmeter. I'm using jmeter 2.9.
I have created a thread group with two threads in it. I have set up an HTTP Request Defaults for the thread group. I have created User Parameters to define person IDs that I'm going to be working with in each thread.
I then set up two HTTP requests. One for login, one for retrieve person. For the login one, I created a regular expression extractor to extract the session key that comes back. I then supply the session key as the parameter for the retrieve person request.
I then sniffed the net traffic and started jmeter test. I wanted to make sure the session key was getting passed into the second parameter OK, but it appears to be running on the login twice and then ending. I am getting a 200 return on the HTTP packet and my jmeter test was set to continue regardless.
I believe I followed chapter 5 of the jmeter user manual to set up this test with the addition of parameters, user parameters, and the regex extractor.
Can anyone give me an idea what i might have done so that the second request never runs?
Add "View Results Tree" listener to see what jMeter is actually doing? You should also check jmeter.log to see if there are any exceptions while generating the 2nd request.
How to use JMeter with ajax request?
I have a button with is clicked and by using fiddler I can find the session id which is being sent to the server.
What should I do next using the JMeter in order to handle this.
EDIT:
Let's say I have in my hand the header which call the request. The JSESSIONID AJAXREQUEST
and so on where should I put it ?...
I putted it in http header manager name and value.
Jmeter will not execute Javascript embedded in your web page. However AJAX request is also a HTTP request that Jmeter will be able to run as a separate HTTP request and upon getting the response you can have post processors (using XPATH or REGEX) to extract the session id in a Jmeter variable.
Alternatively you can record the Jmeter scripts using Jmeter proxy and then all the HTTP requests will be recorded for you and you will just need to attach a post processor manually.
