Project creations are very slow. Use `let_it_be`, `build` or `build_stubbed` if possible.
See [testing best practices](https://docs.gitlab.com/ee/development/testing_guide/best_practices.html#optimize-factory-usage)

Consider adding `feature_category: <feature_category_name>` for this example if it is not set already.
