A developer needs a solution that builds code from an AWS CodeCommit repository, runs unit tests for every change, and provides detailed, accessible test reports. Company policy requires comprehensive unit testing and that test results be available. Which solution meets these requirements?

AWS CodeBuild is a fully managed continuous integration service that compiles source code, runs unit tests, and produces artifacts. It directly integrates with CodeCommit and offers a robust test reporting feature to generate and view detailed reports, fulfilling the requirement for accessible test results. CodeDeploy is for deployment, not building and testing. CodeWhisperer is an AI coding companion and doesn't manage CI/CD pipelines or test reporting. While Lambda could be used, it would require significant custom development for building, testing, and reporting, making CodeBuild a more efficient and purpose-built solution.
