Well the latest version of katalon studio is paid in command line execution, and if Im using the docker image how the licence will work ? is docker image is open source how the execution will work with docker image?
The docker image is just an execution engine, same thing as Runtime Engine which you can freely download from the website.
To execute tests using it, you would need a RE license. For online activation, the license can be automatically searched for and used when you include an API key in your command line to authenticate your account. For offline activation, the license will bind to a machine until it’s expired or 2 months have past.
