I have an application for load testing. I am using JMeter for this purpose. I have added CSV Data Set Config to the While Controller where former reads URL from a csv file. Also, I have added a HTTP request sampler inside the controller.
Now, I have both get and post requests . In addition to that, I have to send file data with few http post requests. Is there a way so that jmeter can decide http request type automatically and create a request accordingly?
Should I create separate While Controller for both GET and POST requests?
You could add method field (post,get) and use an
IfController to eithet call a post or get depending on method value.

I tried to create a test script in JMeter where I log in by using API. I created a test script by BlazeMeter chrome extension.
Some of my API calls fail because I am getting CloudFront error. I found out the issue is that GET requests contain a request body. GET requests cannot contain a request body on CloudFront. When I tried the same get requests in postman without request body, I didn't get any errors. I got the same error in postman if I added a body request. This way I can confirm this is the issue.
I am looking for a way how to remove body request from subsequent GET requests in JMeter to get rid of this error.
This is the original API call (sampler) with POST login api request:
After the POST request there is a redirection to a page that makes other GET api calls to fetch static files such js files, etc. The problem is that these GET requests also contain the same request body as the original POST call.
As you can see I can fetch statis files if I remove body request:
I tried to add preprocessor and postprocessor for original POST request, but I don't know how to access subsequent GET requests. I can access only original POST request:
Is there a filter or a way how to remove body request from GET requests?
I don't think it's possible, at least not with JMeter 5.5
If you take a look at HTTPSamplerBase source code you will see that the request body is being copied fully from the original HTTP Request sampler:
this.sampler = (HTTPSamplerBase) base.clone();
So the options are in:
Raise an enhancement requests via JMeter Github Issues
Amend HTTPSamplerBase code to remove the request data from generated AsyncSamples
Handle embedded resources download manually using Parallel Controller
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.
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.
