AWS Certified Developer – Associate (DVA-C02) — Question 529

A developer is working on a project that requires regular updates to a web application’s backend code. The code is stored in AWS CodeCommit. Company policy states that all code must have complete unit testing and that the test results must be available for access.

The developer needs to implement a solution that will take each change to the code repository, build the code, and run unit tests. The solution also must provide a detailed report of the test results.

Which solution will meet these requirements?

Answer options

• A. Configure AWS CodeDeploy to deploy code from CodeCommit and to run unit tests. Send the test results to Amazon CloudWatch metrics to view reports.
• B. Configure Amazon CodeWhisperer to create the code and to run unit tests. Save the test results in an Amazon S3 bucket to generate reports.
• C. Configure AWS CodeBuild to build the code and to run unit tests. Use test reporting in CodeBuild to generate and view reports.
• D. Create AWS Lambda functions that run when changes are made in CodeCommit. Program the Lambda functions to build the code, run unit tests, and save the test results to a Lambda layer.

Correct answer: C

Explanation

AWS CodeBuild is a fully managed build service that compiles source code, runs unit tests, and natively provides detailed test reporting directly within the console. AWS CodeDeploy is designed for deployment rather than building and testing, while Amazon CodeWhisperer is an AI code companion and not a build tool. AWS Lambda functions are not suited for compiling applications and storing test reports in Lambda layers, which are meant for sharing common code or libraries.
