How to manage Cookies are required error page? - cookies

I am new to jmeter. I record my script using blazemeter chrome plugin. Now in login I am getting Cookies are required Cookies are disabled on your browser. please enable cookies and refresh this page I have set CookieManager.save.cookies=true but no luck .

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 if your page is using JavaScript in order to check user cookies there is no way to bypass this message, it means that you can just ignore it.
However if you cannot proceed further it means that JMeter doesn't send necessary Cookie header so make sure to add HTTP Cookie Manager to your test plan.
If you added the HTTP Cookie Manager but still seeing that the real browser sends cookies and JMeter doesn't (or sends partial) most probably it means that your server returns malformed or expired cookies and you need to raise a defect for your application.
And last but not the least, if you have to live with these malformed/broken cookies and still need to log in you can go for the following workarounds:
Change "Implementation" of the HTTP Cookie Manager to something less restrictive, i.e. netscape
Add the next line to user.properties file (lives in "bin" folder of your JMeter installation:
CookieManager.check.cookies=false
Increase JMeter logging verbosity for the HTTP Cookie Manager by adding the next line to log4j2.xml file:
<Logger name="org.apache.jmeter.protocol.http.control" level="debug" />
this way you will be able to figure out what's wrong with the cookies
And last but not the least you can always manually extract cookies from the Set-Cookie response header using i.e. Regular Expression Extractor and again manually add them to the HTTP Cookie Manager or HTTP Header Manager

500 internal server error instead of 302 redirect- JMeter

I'm trying to investigate the issue as I mentioned in the subject.
I login to the application and successfully able to land on the home page of my application through my JMeter code.
When I click on "user details" tab , I should be redirected 2 times.
Successfully able to redirect for the first time. For the second redirection I'm getting 500 error code instead of 302 again.
URL for "User details" is a plain URL, doesn't come with any need of correlation.
I have cookie manager with "standard"( tried all other options also on cookie manager)
I see that - cookie value SameSite=None; is also seen at request body along with other values only during the reply of my script(I do not see this in the recorded traffic/even if I cross verify using fiddler).
Would like to know if this can be a problematic. If so how can I remove this.
Try playing with Redirect Automatically and Follow Redirects boxes in the HTTP Request sampler
if it doesn't help - be aware that you can extract the redirect URL from the Location header using Regular Expression Extractor
If you think that the problem is with the cookie you can enable debug logging for the HTTP Cookie Manager by adding the next line to log4j2.xml file (lives in "bin" folder of your JMeter installation:
<Logger name="org.apache.jmeter.protocol.http.control" level="debug" />
this way you will be able to see what's going on under the hood in jmeter.log file as it might be the case that the cookie is broken somehow (expired, wrong path, etc.)

Jmeter - How to send Cookie with the http request inside in the Header manager (not Cookie manager)

For the purpose of my test, I need to send Cookie within the request like bellow.
If I try to do it with Header manager, cookies are ignored
I cant see them into the Request Headers where I need to see them.
Is there any way, how I can send Cokie into the reqest?
Note: Using Cokie managers is not working for me.
CookieManager.save.cookies=true
CookieManager.check.cookies=false
Are set up into the user.variables.
Using Jmeter 5.4.3
You're looking at wrong place, the cookies are displayed under Request -> Request Body tabs of the View Results Tree listener
So you might want to check your HTTP Cookie Manager setup, it might be the case it's "working". If it doesn't - there might be a problem with the cookies returned by your application, i.e. it's expired, domain mismatch, path mismatch, etc.
In that case you need to raise a bug for your application or change the implementation of the HTTP Cookie Manager to something less restrictive i.e. netscape
You can see what's going on under the hood with the cookies by increasing JMeter logging verbosity for the HTTP Cookie Manager.
Add the next line to log4j2.xml file
<Logger name="org.apache.jmeter.protocol.http.control" level="debug" />
and upon JMeter restart re-run your test and take a look at jmeter.log file, you should see the incoming cookies and whether they're going to be added to the next request or not.

JMeter 5.4.1 Cookie Manager - User-Defined Cookie not added to request's cookies

Firstly, I did add the line CookieManager.check.cookies=false to jmeter.properties.
What I'm Trying to Do
I want to add a cookie to a request's existing cookies.
For example, I see the request has [edited]:
Cookie Data:
c1=sfasfsfsfsfs; c2=erqwerqwrr; c3=poiuopiupoi
Expected Results
I would like it to have:
Cookie Data:
c1=sfasfsfsfsfs; c2=erqwerqwrr; c3=poiuopiupoi; partner=favicon.ico
Here is what I tried:
BASE_URL_2 is a variable defined in the form qa.company.com.
Actual Results
Whatever I have tried so far has not made any change in the cookies.
What else shall I try?
Underlying Motivation
Recorded a Web session and played it back.
Added a RegEx Extractor to pull out a token and then added it to subsequent requests. That helped.
However, certain requests failed with an custom application exception Security violation, please refresh.
Probably session login state is not being passed, so the website thinks the call is "stale".
I've seen this on the GUI when the session expires and you try to click a button on the site.
On comparing the cookies seem in JMeter with what I saw in the Chrome Debugger, it was clear that there were more cookies in the running application than what I had in JMeter.
Are you sure you're using HTTPS protocol because if you have secure flag and using HTTP protocol - the cookie will not be sent.
Also remove = from partner= otherwise you will end up with partner==favicon.ico

Jmeter HttpRequest shows "browser is currently set to block cookies"

I am new to Jmeter. I tried to send an HTTP request but the HTTP response showed "cookie is blocked"
enter image description here
I tried to create the HTTP Cookie Manager and set the cookie policy as Compatibility but doesn't work.
and also tried to set CookieManager.save.cookies=true in JMeter.properties file, but both don't work.
Any suggestions would be appreciated.
If this is a very first request - no cookies are involved, most probably the application you're testing tries to set a cookie via JavaScript and not using Set-Cookie header
As per Apache 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 you need to inspect the page, you're opening using browser developer tools and if the cookies are being created/set by JavaScript - you will need to replicate the same logic using JSR223 Test Elements and Groovy language, check out Modifying Cookies in JMeter with Groovy article for more details.

How to handle google analytics cookie for ex _ga in jmeter

There r some cookies like _ga, jsessionid etc which are part of jmeter recording script but when i replay script these cookies are not handled by cookie manager. How can i send these values in jmeter request . Also i m unable to corelate these cookies . I guess client side js is responsible for sending these cookies.
I m completely blocked. Please help.
JMeter's HTTP Cookie Manager stores valid cookies which are coming in Set-Cookie response header, the invalid ones are being discarded.
You can inspect what's going on there by adding/uncommenting the next line in log4j2.xml file
<Logger name="org.apache.jmeter.protocol.http.control" level="debug" />
If you see the evidence that cookies are detected but not stored you can try the following:
Set Cookie Policy to something less restrictive, i.e. netscape
Add the next line to user.properties file:
CookieManager.check.cookies=true
