Description

Summary

Removing the data-testid from icons only for production is very confusing because if you run e2e tests with the production version, as we do, you might have your tests running locally when implementing them, because you use the dev version, but have them fail on CI that uses the prod version. If you forget about this point you might have to wait for the CI to finish to figure out the issue. This also makes debugging very difficult unless you're aware of this subtlety.

Is it possible to add some flag/env var to opt out of removing the data-testid?
