How to resolve Root CA Certificate message in JMeter – Windows 10

Recently, I have installed Windows 10 Technical Preview in my primary laptop at my own risk. Windows 10 works like a charm; though with known bugs. I have started testing testing tools such as HP LoadRunner, HP UFT, and Apache JMeter etc. in Windows 10 – Build 9879.

I have already installed above said software, I was able to install without any issues. The prerequisite is to install latest version of Java.

When I launched JMeter, it picked up the jar files from my UFT installation by loading HP UFT Java Support. Later I tried to record a new script by adding HTTP(S) Test Script Recorder and Thread Group.

I changed the proxy setting in my Internet Explorer and clicked on Start in JMeter. Once I clicked, I got following message.

  1. Hi i used their above step , i getting “The Import was successful” popup also. after this message i “start” script in jmeter but again i getting root CA certificate pop up, any other way to resolve this issue

  2. I would like to capture gmail with jmeter. so i am trying to record the script. but once i have started jmeter script and open the gmail in browser. i am getting below exception in browser.

    gmail.com uses an invalid security certificate. The certificate is not trusted because the issuer certificate is unknown. The server might not be sending the appropriate intermediate certificates. An additional root certificate may need to be imported. (Error code: sec_error_unknown_issuer)

    how to solve this issue.

    Thanks in advance

    1. You have to add the certificate to Internet Explorer under Trusted Certificates. You can find the Root certificate in bin folder. I will write a detailed post on this soon 🙂
