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.

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.
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 trying to test a few functions on my Laravel based website. However, I'm having difficulties logging in the website. I've used BlazeMeters Chrome plugin to record my events and save it in jmx file. Was able to do that and imported the file in JMeter. Now at login we are not just examine the email and password, but also a _token variable. This is individual for all visitors. Do I need and if yes, then how can I fetch the token for one user and use that at login time and any other time, when the _token was requested?

Your test flow should look like:
Open Login Page (usually HTTP Get Request)
Extract the token from the response using one of JMeter's Post-Processors (normally people use Regular Expression Extractor or CSS/JQuery Extractor)
Perform Login (usually HTTP Post Request) providing credentials and the token from the step 1
The process is known as correlation and there is a plenty of information on it over the Internet.
If you want to get things done faster you could consider an alternative way of recording a JMeter test scenario which automatically detects dynamic parameters, generates the relevant post-processors to extract them and store into JMeter Variables and substitutes parameters with the variables so you won't have to do it manually.

I am getting the following error while searcing for an entity after successful login
Full authentication is required to access this resource unauthorized
I tried to correlate the items in response headers (VCAP_ID, JSESSIONID) but nothing works. I also observed that the
"sessionToken":"Undefined"
Please provide resolution.
First of all try adding HTTP Cookie Manager to your Test Plan
Double check your correlation post processors using Debug Sampler and View Results Tree listener combination to ensure that all variables are properly extracted. The latter one allows inspecting request and response details as well and has i.e. RegExp Tester mode allowing validating your Regular Expressions against server response without having to re-run the request
If after all you won't fell comfortable with handling dynamic parameters in JMeter you can try out an alternative option of JMeter scripts recording which is capable of exporting the recorded test in "SmartJMX" mode automatically detecting and handling any dynamic values. See How to Cut Your JMeter Scripting Time by 80% article for more details.
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.
