Save response from certain WEB resources while recording scenario - jmeter

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.

HTTP POST Request to a login form doesnt work in Jmeter

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

I have to login with multiple users and like or dislike the post using JMeter

My website is like Facebook. I need to login with multiple users and like the post from all the logins. Now using JMeter i can able to successfully login with multiple users but i can't like it from all the logins.I have recorded the script to like the post from one login. Please assist how can i achieve this. I am attaching my HTTP Request below.
Normally "like" is a HTTP Request which should be implemented via the HTTP Request sampler so you need either create the relevant request manually or simply record it using HTTP(S) Test Script Recorder
Once done you might need to perform the correlation - the process of identifying dynamic parts of the requests, using Post-Processors to convert the values into JMeter Variables with the recorded hard-coded values with dynamic variables.
Check the request and response details using View Results Tree listener and if you're happy with what your test is doing you can start adding more virtual users to check how does your application under test behave under the load.

Unable to get security token for Jmeter

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.

Response message: Unauthorized in Jmeter

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.

Jmeter POST request from recording does'nt effect the webpage but getting passed

I have recorded the steps of creating user using badboy. i have tried the same script using Jmeter. All steps getting passed, but its not effecting. I mean Jmeter is not creating the user in the webpage. Badboy is able to create the user.
Please guide me.
JMeter isn't smart enough to automatically do the test for you.
First of all you'll need HTTP Cookie Manager to simulate browser cookies, deal with sessions, cookie-based authentication, etc.
Also the majority of web applications use kind of page-level state-management mechanisms like VIEWSTATE which can be vital
And finally your user creating request may be missing some mandatory dynamic parameters which are being passed along with the request.
The answer to points 2 and 3 is correlation - the process of extracting dynamic values from page, storing them to variables and re-using them in next requests. JMeter offers several options for this called Post Processors, the most commonly used are:
Regular Expressions Extractor
XPath Extractor
CSS/JQuery Extractor
JSONPath Extractor (available via plugin)
I would suggest to record your use case several times, inspect what values are being sent using View Results Tree Listener, detect those, which are dynamic, use extractors above to fetch dynamic data and add corresponding variables to your user-creating HTTP Request.
Hope that it's clear.
D.
