The correct service for the scenario described is CodeBuild, which has the capacity to automatically execute unit tests and other commands each time there is an update to the repository, ensuring that new commits don't break the application. CodeDeploy is mainly focused on deployment tasks and doesn't inherently run tests. CodePipeline is responsible for orchestrating the flow of updates, rather than executing the tests themselves. CodeCommit is a source control service and does not directly handle testing; it would integrate with other tools to achieve this functionality.
