Everywhere I look I see that jmeter turns off certificate verification by default.
Its documentatoin says "The JMeter HTTP samplers are configured to accept all certificates, whether trusted or not, regardless of validity periods, etc. This is to allow the maximum flexibility in testing servers."
Is this a configuration option, or there is no way to configure it?
I would like to have jmeter to verify the certificate, as part of the test. I have tried example in this answer, however it didn't fit our needs
Thanks
There is no "switch" to enable/disable the SSL verification in JMeter, you will have to patch LazyLayeredConnectionSocketFactory.checkAndInit() function in order to enable certificate checking functionality.
Once done you will need to build JMeter
As a workaround you can utilize Apache HttpComponents and define your requests via Java Request or JUnit Request or JSR223 Sampler

How can I apply the SSL verification disable process that I performed in Postman in Jmeter?
As per JMeter Documentation:
The JMeter HTTP samplers are configured to accept all certificates, whether trusted or not, regardless of validity periods, etc. This is to allow the maximum flexibility in testing servers.
So SSL verification is "disabled" in JMeter by default and by design, there is nothing you need/can do about it.
The funny thing is that there is no easy way to enable it, if you need to test SSL handshake or want JMeter to fail if the SSL connection is not secure - you will have to write the code for establishing the connection using JSR223 Samplers and Groovy language.
Update your jmeter.properties that is read when jmeter starts up, add the following:
server.rmi.ssl.disable=true
New to Jmeter so I am not sure if my set-up is correct.
Basically I have these set of API's that I need to Perf test. Starting with a setting up a basic connection from Jmeter - I am receiving 1020 error from cloudflare
Access denied | "domain" used Cloudflare to restrict access
and
<div class="cf-alert cf-alert-error cf-cookie-error hidden" id="cookie-alert" data-translate="enable_cookies">Please enable cookies.</div>
It works with POSTMAN. So wondering what changes I'll need in jmeter.
I have enabled save cookie in jmeter.properties file
API is for logging into a portal: verified username/password. VPN connection verified as this works from postman.
If you're absolutely sure that the request works in postman (although I'm getting this 1020 error even with the real browser) you should be able to get the same behavior in JMeter as well, just make sure to send the identical request (pay attention to HTTP Headers as well)
The easiest is just recording your Postman request using JMeter's HTTP(S) Test Script Recorder, just configure Postman to use JMeter as the proxy
and run your request - JMeter will generate appropriate HTTP Request sampler and HTTP Header Manager
If you need to use VPN for proper access you might need to configure source IP address at the "Advanced" tab of the HTTP Request sampler like it's described in Using IP Spoofing to Simulate Requests from Different IP Addresses with JMeter article
In any case load testing an API behind Cloudflare might be not the best idea as Cloudflare provides DDoS protection and may (and will) block this type of traffic so you need to either whitelist your IP address(es) or let them know about your load testing activities, I believe they will be able to suggest a better workaround than anyone here
This is related with the securities features of CloudFare, either DDos protection or bot blocking. Exceptions can be configured from the CloudFare control panel.
If you don't have access to this panel you'll have to ask the corresponding person inside your company tasked with this job.
We have an application where it is enabled with Windows Authentication where it has Negotiate and NTLM in the provider module. It seems that Jmeter is preferring to send the request using the Negotiate and is failing whereas when tried from LoadRunner, we see that it is always sending as NTLM and it passes from there.
Has anyone come across this kind of situation? If yes, how can we force Jmeter to use NTLM authentcation rather than Negotiate?
Thanks for help.
JMeter doesn't "prefer" anything, it depends on the HTTP Authorization Manager configuration which you have to perform.
Your test should implement real user behavior, not LoadRunner behaviour, if real browser performs Kerberos authentication - you need to do this and vice versa.
To force JMeter to use NTLM just make sure not to select KERBEROS mechanism, use BASIC_DIGEST.
Check out Windows Authentication with Apache JMeter article for more details if needed.
I am writing load test script for an SAP-based application in jmeter. I am getting 500 internal Server.
I saw that the request looks same which I have on the browser network tab and the one I provided in JMeter. The only difference is in the request header, that I am not providing any SAP-passport in my request. I am not to see the SAP-Passport in the response of any previous request's response so that I can extract that and use in future requests.
Please tell me if I am assuming correctly that the SAP-Passport is the issue, if yes then how can I get that and use in the request. Also if there is a way to get any static SAP-Passport.
Its a blocker for me and its on priority, please help.
As far as I can see from Single Sign-On with SAP Passports article it is a matter of adding a client certificate to JMeter.
Obtain SAP Passport root certificate somehow (i.e. export it from your browser)
Add it to JMeter. This can be done in 2 ways:
Using SSL Manager
Using JMeter system.properties file
Check out How to Set Your JMeter Load Test to Use Client Side Certificates guide for comprehensive instructions on both approaches.
How to record user input parameters using JMeter? I tried to use the record controller and follow through the tutorials, all the records are only http get requests without any post input. Thanks
Properly configured JMeter captures all network activity between browser and application under test, the fact you don't see POST requests might indicate one of the following:
Browser simply doesn't make any POST requests, i.e. your application is designed to operate only GET HTTP Request types
Your JMeter configuration is not correct, i.e. your application uses HTTPS. In this case you need to perform some extra configuration so JMeter could intercept, decrypt and record HTTPS requests:
make sure your browser is configured to use proxy for all protocols
make sure you install JMeter's self-signed certificate to your browser. The file name is ApacheJMeterTemporaryRootCA.crt and it is being generated in "bin" folder of your JMeter installation when you start JMeter Proxy Server
