I would like to run UI automated tests for my WordPress plugin. I am using Docker to run a WP instance and it runs my tests, that is fine. I am using
wp-cli to install and config a testing site.
I would also like to run the test suite on multisite. For that, I need to setup a network. I know how to install a multisite network manually, but I need a command which I add to my Dockerfile. So my question is: Is there a way how to create a multisite network using command line script?
