Hi @jhonatan-lopes, I noticed this PR introduces new strings in network-api/networkapi/wagtailpages/factory/customblocks/link_block.py, before I expose them in Pontoon, I wanted to check whether actually translating these strings would be helpful for these tests, and if not, whether we should hardcode the strings, or even maybe exclude all test folders from the makemessages command?

Hey @TheoChevalier, don't bother exposing them to Pontoon just yet. These strings are only used on the admin interface so there's no need for localisation (or a lower priority need). The tests need it because the wagtail-link-block library makes use of it. In any case, I think I'll need to remove that library before it goes to prod because it is not entirely compatible with how I need to setup links on the new navigation work.

So, moving forward I'll either remove those strings (by removing the library) or I'll try to exclude the test folders from the makemessages command
