I have been using JMeter for a while and I am facing a problem in particular related to logout. I am using the below script -
TestPlan
HTTP Cookie Manager
HTTP Request Defaults
ThreadGroup - (scheduled for half and hour)
Once Only Controller
HTTP Request - login
Loop Controller - (forever)
HTTP Request 1
HTTP Request 2
....
HTTP Request 13
tearDown Thread Group
HTTP Request - logout
But the problem here is that even the logout response looks good , the user used for JMeter script login is still actually not logged out. (that i can monitor as as Admin)
Most likely your "Logout" link just clears user's cookies via JavaScript. As per Apache JMeter project main page:
JMeter is not a browser. As far as web-services and remote services are concerned, JMeter looks like a browser (or rather, multiple browsers); however JMeter does not perform all the actions supported by browsers. In particular, JMeter does not execute the Javascript found in HTML pages. Nor does it render the HTML pages as a browser does (it's possible to view the response as HTML etc., but the timings are not included in any samples, and only one sample in one thread is ever viewed at a time).
So Logout event can be simulated in JMeter by clearing cookies - see "Clear cookies each iteration" box in the HTTP Cookie Manager
NB: Iteration in the HTTP Cookie Manager (as well as in HTTP Cache Manager, etc) is something which is being defined and incremented at Thread Group level, loops triggered by Loop Controller, While Controller, etc. are not considered as "iterations"
It it also possible to clear cookies programatically i.e. from Beanshell Sampler

During manual run on reaching the Home screen, the page keeps loading and the API calls timeout with 504 error(Received the same error during Jmeter execution)
But if the same page(Home screen) is refreshed three times manually, all the previously timed out APIs load successfully (status:200).
But I'm unable to identify how to refresh the page using Jmeter. Any help on this? Thanks!
I tried adding JSR223 preprocessor with the following Javascript -
load("API-url") in the script section but it doesn't seems to work.
As per JMeter project main page:
JMeter is not a browser, it works at protocol level. As far as web-services and remote services are concerned, JMeter looks like a browser (or rather, multiple browsers); however JMeter does not perform all the actions supported by browsers. In particular, JMeter does not execute the Javascript found in HTML pages. Nor does it render the HTML pages as a browser does (it's possible to view the response as HTML etc., but the timings are not included in any samples, and only one sample in one thread is ever displayed at a time).
So in order to "refresh" the page you need to send the same HTTP Request to it using HTTP Request Sampler. If you want to send the same request more than once it makes sense to put in under the Loop Controller
Also given the above quote from JMeter documentation if loading the page triggers some AJAX requests to the API - JMeter won't execute these requests automatically, you will need to create a separate HTTP Request sampler per API request. Also real browsers execute AJAX requests in parallel so if there is more than 1 API request - you need to put them under the Parallel Controller
The scenario is- After logging out from application either i have to close the browser or have to clear the cache in order to login with same user again, else browser will not give me login page and it will directly redirect me to post login.
When i am running my script from jmeter, its failing for 2nd iteration as its not able to find out the login page.
what needs to be done in jmeter for handling this scenario? i have added http cache and cookie manager in test plan.
I already tried
1.JSR223 Post Processor- sampler.getCacheManager().clear()
2.BeanShell PostProcessor- import org.apache.jmeter.protocol.http.control.CookieManager;
CookieManager manager = ctx.getCurrentSampler().getProperty("HTTPSampler.cookie_manager").getObjectValue();
manager.clear(); for all 3 requests of Logout transaction.
There is Same user on each iteration setting on Thread Group level.
If you untick it - both HTTP Cookie Manager and HTTP Cache Manager will be cleared when a thread (virtual user) starts new iteration. (only applies to Thread Group's iterations, controllers like Loop, Foreach, While, etc. won't be impacted)
If you want to proceed with scripting and copy-pasting the code without understanding what it's doing for JSR223 Post Processor the relevant code would be:
prev.getCacheManager().clear()
prev.getCookieManager().clear()
but make sure to place it as a child of the last HTTP Request sampler, see JMeter Scoping Rules - The Ultimate Guide article for more information on the impact of placement of JMeter test elements
Browser shows all cookies when we hit home request
These are the cookies that appear in browser when we execute home page 1st time, but not in Jmeter request
Its JMeter response that shows cookies
My issue is when I execute home page in browser it shows all cookies 1st time when we hit request but in JMeter home request don't show up all cookies as shown in picture.
I want cookies values i.e. ai_user & ai_session and pass them to UserSessionId & AppSessionId in HTTP request header. So how do I get those values? I already user HTTP CookiesManager in my script to handle cookies but can't get ai_user & ai_session cookies values.
Given you send the same request in JMeter as in the real browser you should get the same response so double check all the request details like:
URL
Headers
Body
etc.
Try using clean browser session or at least private mode
Look at Set-Cookie header for the first request and see if the cookies you're looking for are there. It might be the case that the cookies are being set by JavaScript and as per JMeter Project main page
JMeter is not a browser, it works at protocol level. As far as web-services and remote services are concerned, JMeter looks like a browser (or rather, multiple browsers); however JMeter does not perform all the actions supported by browsers.

Nor does it render the HTML pages as a browser does (it's possible to view the response as HTML etc., but the timings are not included in any samples, and only one sample in one thread is ever displayed at a time).
So if this is the case you will need to mimic the JavaScript code logic using JSR223 PostProcessor or just extract the values from the response if they are there using other suitable Post-Processor
I am trying to run a simple test in jmeter but i am stuck. The steps are:
Log in
Set the Cookie Manager
Access the landing page
The first 2 steps are successful, but i get status 403 "errorId":"AUTHENTICATION_REQUIRED" on the 3rd step. My guess is it is not getting the session from log in, but everything i 've tried hasn't worked. Here is my test plan:
Any suggestions?
JMeter's HTTP Cookie Manager obeys JMeter Scoping Rules, so if you put it as a child of the Setting Cookies request it will be applied to that request only, therefore cookies will not be available to the Landing Page
Try moving the HTTP Cookie Manager one level higher so your test plan would look like:
You should be able to see which cookies are being received and sent out using View Results Tree listener
I am testing particular application using JMeter 2.9.There My test plan is Thread group--> Transaction Controller.Inside that various recorded requests are there.I am using HTTP request defaults,HTTP Cookie manager and HTTP header manager,and a view result tree for validation.I found one token i.e. CSRF token to be correlated and I did correlation.But for a particular request I am finding "Session expired..Login again" response much before the logout request.My transaction flow is to Login--> Search a content-->Logout.
Please help me finding a solution.
Try put the element: HTTP Cookie Manager in Thread Group, first item.
the problem can be in the following areas:
-you were redirected automatically instead of following redirects
-login hasn't succeeded
-the session id has not been successfully passed on to the request after login
The JMeter documentation states this:
I've set up JMeter to sample the same URLs as my browser, why is JMeter not seeing the same responses?
There are various different reasons for this:
Cookies - make sure you added a Cookie Manager. Browsers process cookies unless you set them up otherwise, but JMeter does not process cookies unless you add a Cookie Manager.
User-Agent - the User-Agent is a header that is sent by browsers; it identifies the browser type. Some servers are sensitive to this setting and generate different results for what they think are different browsers. The Header Manager is used to add headers such as User-Agent.
Hidden fields - if you did not use the JMeter Proxy (or other application) to record the test plan, then it is easy to miss hidden fields from forms.
Dynamic field names/content - some servers use varying names for fields. So although the test plan may be correct at the time of creation, it does not work when replayed.
URL rewriting - TBA
