Explanation

This question tests knowledge of GitHub Actions workflows and deployment protection rules used to control code testing triggers and build approval gates in a CI/CD pipeline.

Approach. For the first requirement (ensuring code is submitted for testing only when a build completes successfully), you should use a GitHub Actions workflow with a job dependency using 'needs' keyword or configure a workflow trigger on 'workflow_run' with status 'completed' and conclusion 'success' - this ensures the test job only runs after a successful build job. For the second requirement (ensuring a build is approved before release), you should use GitHub Environments with required reviewers (Environment Protection Rules) - this pauses the deployment workflow and requires manual approval from designated reviewers (the change management team) before the build proceeds to the release/production environment.

Concept tested. GitHub Actions CI/CD pipeline design, specifically job dependencies ('needs' keyword or workflow_run triggers for sequential job execution) and GitHub Environment Protection Rules with required reviewers for manual approval gates before deployment.
