to performance test a UI


  • Run Gatling recorder
  • Once the gatling recorder proxy has been started, configure this proxy in the webbrowser that will be used for the test
  • Login to the UI
  • Navigate to the website
  • Save the recording


When a http site is recorded, then it is recorded, but when an https site then gatling records nothing


Gatling can record websites, but when these are encrypted then one could define the following:

HTTPS mode:

  • self-signed certificate
  • provided keystore
    • keystore file
    • keystore pasword
    • keystore type
  • certificate authority
    • ca certificate
    • ca private key

  • Checking again, I still don't get why you can navigate to the UI through gatling recorder but not recording anything, don't you have some company management system breaking your browser configuration when you point it to gatling ?

1 Answer 1


If it is possible to switch https to http temporarly then gatling can record the clicks. When the recording was done, https was activated again and the test could be run against https as well. In summary, recording works if the site is http and running it works against https. Note that the recorder file contains http and this need to be changed to https.
