Who should add the data-testid? Or, how we automated this process.

Our team faced a recurring conflict: developers would forget to add data-testid attributes, testers couldn't write stable tests (and weren't allowed to add the IDs themselves), and time was wasted hunting down missing IDs. Developers viewed the task as tedious busywork. So, we created GenTestID—a CLI tool that automatically injects data-testid attributes into all Vue and React components with a single command. It takes just a few seconds. No more arguments, no more tedious chores, and no more forgotten IDs.
