How to make working login into Laravel 5.+ with JMeter? - jmeter

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 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.

E commerce load test with complete flow

I'm trying to do a load test of e commerce site with complete flow from product search, login to add to cart and submit. Product search and anonymous order is working fine but when I'm trying to run script for registered user it's not working. How can I fix this?Click here to download script
Your "download" link is broken or expired or whatever.
Most probably your request doesn't work for authorised users due to missing or improperly working correlation. Modern web applications cannot be just recorded and replayed as they widely use dynamic request parameters mostly for security reasons. So if this is the case your test needs to look as follows:
Open Login Page (usually GET request)
Extract dynamic parameters using one of matching JMeter Post-Processors and store them into JMeter Variables
Perform Login (usually POST Request) providing not only credentials, but also dynamic parameters values from the first request
Also make sure you add HTTP Cookie Manager to your Test Plan - it represents browser cookies and automatically deals with cookie-based authentication
You might want to try an alternative way of recording a JMeter test - using cloud-based proxy which is capable of exporting recorded tests in "SmartJMX" mode with automatic correlation of any dynamic parameters detected.

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.
