Question 19

Question

A development team uses AWS CodeCommit, AWS CodePipeline, and AWS CodeBuild to develop
and deploy an application. Changes to the code are submitted by pull requests. The development
team reviews and merges the pull requests, and then the pipeline builds and tests the application.
Over time, the number of pull requests has increased. The pipeline is frequently blocked because of
failing tests. To prevent this blockage, the development team wants to run the unit and integration
tests on each pull request before it is merged.
Which solution will meet these requirements?

Accepted Answer

Create an Amazon EventBridge rule to match pullRequestCreated events from CodeCommit
Create a CodeBuild project to run the unit and integration tests. Configure the CodeBuild project as a
target of the EventBridge rule that includes a custom event payload with the CodeCommit repository
and branch information from the event.

B is wrong, D. If the requirement was about the best way to enforce pre-merge tests (like a gating rule), would that change which AWS service or method you'd pick? The official guide covers this distinction.
