Testing New/Remixed Types Locally


From my understanding, gulp will only display UI changes. How can I test a new remixed type and associated functions in a local environment before submitting a pr to engineering? Do I do the same thing I would do for metrics–upsert the new type in the static/console? If so, how do I upsert a remixed type (I don’t want to overwrite the existing type) and a new/remixed function associated with that type into a local environment?
