I have a JMeter test script that performs logon to a website. I can see the POST request with the appropriate information, but it seems the session is lost after that point, as the next step goes to the homepage expecting to be authenticated but isn't. Any ideas? I can post the code if necessary. I do have a cookie manager configured.
Most probably it's due to missing or improperly implemented correlation, cookies might be not the only one dynamic parameter which you need to take care of, modern web applications widely use others for i.e. client-side state tracking or security purposes.
So inspect your test script and check for parameters which are dynamic, the easiest way is recording the same scenario once again and comparing resulting .jmx scripts. Everything which differs is a subject to correlation.

I am implementing load testing in Jmeter for my web application which uses google oauth.
I have generated access token and refresh token and passed it to my HTTP request, but the request fails with an Invalid state parameter.
I checked various posts on passing a random string of 30 characters but the value is not being recognised.
I am not sure how to use the google API library for python to generate one as there is only snippet available in the official site and am quite unsure if that value will be recognised.
Any suggestions on how to achieve my usecase?
We are not telepathic enough to guess how exactly you "generated" the tokens and how they're "passed to your HTTP request"
My expectation is that you need to pass only one token: the "access" one "to your HTTP Request", refresh token can be exchanged for the new access token when the previous one expires. Passing 2 tokens doesn't make sense and may cause the problem you're facing.
As per the main page of JMeter project
The Apache JMeter™ application is open source software, a 100% pure Java application designed to load test functional behavior and measure performance. It was originally designed for testing Web Applications but has since expanded to other test functions.
hence you cannot use Python libraries directly in JMeter, either look for a Java library, I think this one is a good choice and use it from JSR223 Test Elements
If you still want (or have to) use Python - you can run Python scripts from JMeter using OS Process Sampler
I am trying to run performance test using Jmeter for my client application which uses Signicat, a third part identity verification site for SSO login. I cannot get through with jmeter execution for login. There is a dynamic token appended in one of the http requests related to login but I cannot find it in any of the previous responses to correlate.
Has anybody tried Performance tests with Signicat or any other SSO login ? I appreciate any suggestions or leads. Thank you.
PS: I tried to monitor the traffic in fiddler while accessing the site . I don't see the token source there as well.
Unfortunately your question doesn't contain sufficient level of details.
If you're seeing the dynamic token there are following possible options:
It needs to be correlated (extracted from the previous response), the possible sources are:
URL (as a part of a redirect)
response headers
response body
It needs to be generated, if the dynamic value is being generated by client-side JavaScript JMeter won't be able to execute the JavaScript, you will have to replicate the code using JSR223 PreProcessor and preferably Groovy as the language in order to generate the same value as the real browser does
Looking into Connecting your application chapter there are several possible protocols/options and it will require rather a story than a chapter to provide comprehensive instructions on each of them:
for some of them like "Other third party software" it is not even possible doing this remotely without knowing the infrastructure and the authentication/authorization processes.

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.

I am trying to automate testing of a web application.
I have recorded the test using JMeter proxy template (JMeter version is 3.2) and couple of times when I ran the test in the JMeter it ran properly but after sometime only some part runs properly.
Following are the steps I am doing:
Hitting the URL
Logging into the application
changing some feature in the application
and so on.
All the steps ran perfectly first few times but then after that only till login everything runs properly.
Just to be sure I tried passing the jsessionid from the first request to the next requests using the Regular "Expression Extractor". I can see in the View Results Tree that jsessionid is passed properly but next page after the step two still takes me into the login screen.
Any help will be very much appreciated.
I have attached screenshot for better understanding:
The response header of logged in page includes a sessionid which is used by another request while logging in.
All the sessionID are properly maintained still after logging in the next page takes me to the login page instead displaying what was done next in the recording.
When it comes to load testing of JSF-based web applications you need to take care at least of the following dynamic parameters:
JSESSIONID
javax.faces.Viewstate
JSESSIONID is a normal HTTP cookie so it is quite enough to add a HTTP Cookie Manager to deal with it
javax.faces.Viewstate is client state management mechanism which also acts as a security token to verify user's origin. So you will need to properly correlate it, i.e. extract from previous response using one of JMeter PostProcessors, store into a JMeter Variable and add as a parameter to the next request. Remember to do this for each and every request.
There might be more application specific dynamic parameters, the easiest way of detecting them is recording the same request (or scenario) 2 times, compare the recorded scripts, detect and work around the differences.
JMeter || Facing issue while doing post method for login functionality, please suggest the steps.
I am able to hit the said URL, but when I am passing the parameter I am getting the same response as when I am hitting the URL.
so not sure how to do it for login check.
Your testing needs to be realistic, it means that you need to represent real users sitting behind real browsers as close as possible. What real users do is:
Open login page (usually GET request)
Type credentials
Click "Login" or "Submit" or whatever button (usually POST request)
JMeter doesn't "type" anything so you don't need point 2, but you might need to have something in-between in case your application uses mandatory dynamic parameters for tracking client state or security reasons.
So:
Make sure you have HTTP Cookie Manager added to your Test Plan
Make sure you simulating first request (open login page) prior to posting something there
Make sure there are no dynamic parameters you need to work around. If they are - you need to handle them using PostProcessors
