What behavior can Rob create to ensure features that pass Apex tests are deployed to UAT?

To ensure that features passing Apex tests are deployed to UAT, creating a behavior related to "Connection Behavior" is effective because it would typically pertain to how environments interact during the deployment process. By configuring this behavior, Rob can establish a connection or settings that specifically dictate how code and metadata changes are managed between environments, thus ensuring that only features that meet specific criteria, like passing tests, are included during the deployment to UAT.

Ensuring a reliable connection method facilitates smoother deployments and helps streamline the governance of what gets pushed to UAT, based on testing success. This means that Rob can set parameters for deployment that only allow changes with favorable test outcomes to progress.

The other options, such as manual deployment, while potentially accurate, do not provide the automated assurance that only changes passing tests would be promoted. Test frequency relates more to how often tests are run rather than deployment rigor. Automated deployment does sound effective but in this context requires the proper connection behavior to function correctly, which emphasizes the initial environment setup and criteria for what is to be deployed.
