What I am trying to do:
I am trying to setup a load-test for a SAML authenticated application.
What I have done so far:
I have captured my http traffic in JMeter and setup a scenario.
I have read up on how SAML works and tried to place what I am doing wrong.
But as far as I can see my expectation is viable.
What I run into:
I am having some trouble with the correlation of the SAMLRequest/SAMLResponse values.
My Expected results vs actual results:
I am looking to extract the value of the SAMLRequest and RelayState parameters from the responses I get when I login on my SP (application using SAML)
I login with username + password and then expect the responses I get in my Chrome Dev Tools to contain a SAMLRequest and RelayState
Then I wish to extract the value of SAMLRequest and use it in the next POST to obtain a SAMLResponse, which in turn I wish to extract in order to authenticate myself for the remainder of the scenario.
But I am misunderstanding something or I am overlooking a value somewhere, because I cannot seem to find where to capture SAMLRequest from to be able to reuse it in the first SAML post to get the SAMLResponse.
I only see SAMLRequest and RelayState in the POST of the recorded step, but in order to re-use this scenario I need to correlate these values but have no idea where to get them from as they do not seem to appear in the responses prior to this POST (at least not that I can see)
Where do I extract the value of SAMLRequest from and how?
Like Amol pointed out above, I have found the issue is with the response logging or lack thereof in the Chrome Browser.
I have switched to FireFox and was able to view the expected responses I was looking for.
Whereas in Chrome these Responses were empty according to the Dev Tools.
The issue was fixed by correlating the values as you would normally expect within JMeter, which was made possible now I knew where to look for them.
Thank you Amol!

I am trying to do some basic performance testing on an app I look after.
I am using Jmeter and done the steps recorder and the same as following Jmeter tutorials on youtube, but I am getting stuck when I need put the variable into the X-CSRF-Token
The issue is I cant find X-CSRF-Token in the captured steps. Is it using some other form of authentication? Any suggestions for me as to other methods would be great.
If the post doesn't make much sense, I don't really have an in-depth knowledge of Jmeter or testing.
To find where the token appeared:
clear browser history
record your scenario using jmeter recording template
then in the view result tree located un HTTP(s) Test Script recorder, use the search field to find the first response in which it appears. You’ll need to add an extractor in the corresponding sampler
you ‘ll then be able to inject it using ${varName}
Depending on your server configuration this X-CSRF-Token can come in:
In the response HTML body
In the response headers, inspect HTTP Header Manager for any hard-coded values
As a HTTP Cookie (which is basically a header as well, however it will be much more convenient to get it from the HTTP Cookie Manager rather than from response headers)
So make sure to inspect all the tabs of the first request in the View Results Tree listener as this X-CSRF-Token guy can hide anywhere.
You can try an alternative way of recording a JMeter test, it can export test in "SmartJMX" mode with automatic detection and correlation of any dynamic parameters including but not limited to CSRF tokens so theoretically it can make your life easier, check out How to Cut Your JMeter Scripting Time by 80% guide for more information and technical details.
If you need further help you will have to provide more details, like full dump of 2 requests along with responses. You can use a sniffer tool like Wireshark or Fiddler to capture it.
I'm new to using Jmeter tool.
I have recorded my application using blazemeter (v3.1) and then trying to run that .jmx file in Jmeter, however I am running into an authorization issue and the script fails to run.
I have also tried setting my "HTTP Authorization Manager" with username, url, password but it does not help. If anyone can, please guide me on this Issue. Thanks.
As per 4 Things You Should Never Do with Your JMeter Script article:
Don’t run the script exactly as you recorded it
After recording your script, there is still some work to do before you run it. It’s necessary to correlate variables, parameterize and add elements, to faithfully simulate users.
There are too many ways of possible authentication implementation in your application, most probably you need to send some dynamic value along with credentials which can be fetched from the previous request.
Record your test scenario 2 times and compare recorded requests. Be careful as differences might be in response headers and URL, not only in response data. It makes sense to add View Results Tree listener directly to HTTP(S) Test Script Recorder - this way you will be able to see what data is captured by JMeter and amend its configuration so simulated request would look exactly like the request from the real browser.
I want to do performance testing of my site which uses the Azure AD authentication. In order to login to the site 3 requests are called.
in first request the clientid is passed
in the second request in the URL it is creating one parameter 'tx' and it has some value. Rest it creates the csrf token which I am extracting successfully.
But I am facing problem in extracting the value of 'tx'
I am checking the value in the previous requests response but I am not able to find it. Is there anything that I am missing? I checked it on Fidler too somehow I am not getting the value of the tx.
I would suggest that you perform the login action in Chrome (say) with Developer Tools > Network open - and on the second request (sending 'tx') get the value that is sent by the browser, then search for that value in the previous response - and find how that is represented as parameters in the downloaded data.
I had a similar requirement and ended up Writing PostProcessor (to extract a value and save in a variable) and PreProcessor (to inject the variable value into the posted parameter) - you may need to process HTML, javascript or embedded JSON in the initial response.
The fact is that (more-and-more) Web Applications are embedding functionality in client-side javascript and you need to set JMeter up to emulate this.
In my script, I'm using a JSESSIONID instead of a cookie; the JSESSIONID is extracted using a HTTP URL Re-writing Modifier and I can confirm that the correct value (the one which appears in the response data from the login page) is being applied in the Request.
e.g. POST https://qa67.ososinfo.org:446/Staff/staffdetail.xhtml;JSESSIONID=0655ca5420354753ae413984d34cfc27
I'm also using a VIEWSTATE, which I'm extracting prior to running the remainder of the test steps by using a Regular Expression Extractor and setting the resulting variable as a parameter in the HTTP Request,
e.g. javax.faces.ViewState=8d2%2BgOIseczB2FWSo74DqQfkmiYVaK73D8bnLTNWCx%2FB8EtE
The problem is that I'm hitting a Response code: 500 | Response message: Internal Server Error every time I attempt a post with all of the applicable data.
I tried running through the steps manually in a Firefox browser. I copied the contents of the Request tab from the failing page into a REST client, logged in using a separate tab of the same browser and grabbed the appropriate JSESSIONID and VIEWSTATE information, then posted with that info in place - and the manual post was successful.
Am I missing something? Is JMeter requiring something to accomplish this POST that a I'm not seeing in a manual attempt? Please note that I can verify the test is working through the point of login - I can manually see the jmeter user logged in from an admin screen.
Happy to share any/all of what I'm seeing if it might be helpful in helping to troubleshoot.
I need to create scenario for user interaction with single-page WEB application. The application does lots of AJAX calls in order to authenticate user and get user data.
So I created simple scenario with HTTP Test Script Recorder and tried to record my script.
Everything went well, however I noticed that whilst request data is recorder properly, the response data is not recorder at all. I tried to enable Add assertions and Regex matching - but that didn't work as well.
Can you please advice how do I record response texts as well?
View Results Tree under proxy will record request, responses during recording.
This is useful to understand where a dynamic field comes from. This will help your find from which response X you need to extract data to inject in request X+N.
I think you may find this option useful to add in user.properties:
proxy.number.requests=true
This will give a number to each request and corresponding sampler so you will be able to find response for the request.
Once you have done this, you will start adding Post Processors (Regex, CSS/JQuery, XPAth ...) to Sampler X to extract data from its response.
This will create variables you can then use as ${varName} in request X+N.
