Which of the following is a feature of Looker’s Git integration?

In Looker’s Git integration, in-line commenting on pull requests is a key feature that enhances collaboration among developers. This functionality allows team members to review changes made in code by leaving comments directly on specific lines of the code during the pull request review process. This interaction enables better communication and aids in resolving questions or concerns before the code is merged into the main branch.

Furthermore, the in-line commenting feature helps maintain a transparent development process, as it provides a history of discussions and decisions made about particular code changes. This can be particularly useful for new team members or anyone reviewing the project later, as they can see not only what changes were made but also the rationale behind them.

Other features like automatic testing of commits, local repository storage, and direct SQL execution from Git are not standard offerings within Looker's Git integration. While testing, local storage, and direct SQL functionalities could be relevant to a development workflow, they are not specifically features associated with Looker’s Git integration in the same manner as in-line commenting.
