Exam AWS Certified Developer - Associate DVA-C02 topic 1 question 245 discussion

BE is the correct answer.

B. The AWS CDK assertions library provides a convenient way to write unit tests for CDK applications. It allows developers to assert various aspects of the CDK constructs, such as properties and resource counts. Integrating these unit tests into the CI/CD pipeline ensures that they are automatically run after any commit, providing continuous validation of the infrastructure code. E. Aspects in AWS CDK are a way to apply operations to all constructs in a CDK app or a part of the app. By using the Aspects class, the developer can create custom rules (like security configuration checks) and apply them across all constructs in the CDK application. If these rules find any violations, the stack synthesis can be set to fail, ensuring that the application adheres to critical security configurations.

Option B: The standard approach to testing AWS CDK apps uses the AWS CDK's assertions module https://docs.aws.amazon.com/cdk/v2/guide/testing.html Option E: By using the CDK Aspects class to create custom rules, you can enforce specific conditions or checks on your CDK application, including security configurations. Failing the stack synthesis if any violations are present ensures that deployments do not proceed if critical security configurations are not met. CHATGPT 3.5

Option B allows writing unit tests for the infrastructure code using the built-in CDK assertions. Running them in a CI/CD pipeline on commits provides automated testing. Option E lets you define security validation rules as Aspects, which run on synth to catch issues early.

B. Use the CDK assertions module to integrate unit tests with the application. Run the unit tests in a continuous integration and continuous delivery (CI/CD) pipeline that is invoked after any commit to the repository. E. Use the CDK Aspects class to create custom rules to apply to the CDK application. Fail the stack synthesis if any violations are present.
