Until now the testing flow has been pushing changes to Balm and testing them in consuming mods. With Balm now being used by people other than me, we're currently lacking an easy way to test new features that aren't used by my own mods.
There should be a testmod project (common-test, fabric-test, neoforge-test, forge-test) included in this repository that can be used to verify new additions work as expected and test for regressions in ports.
