Testing LineItem.properties in Script Editor

Hi folks,


I'm trying to write some functionality that reads and reacts to line item properties, set during the add-to-cart process.


However, in the script editor environment I can't see a way to set such properties on the Cart Input line items. Instead I have to keep publishing, running a live checkout, and unpublishing the script as I work, which is painfully slow and prevents me seeing script console output.


How can I set properties in the Script Editor test cart input?
