Which solution should the developer implement to meet these requirements?
Run the amplify add test command in the Amplify CLI.
Create unit tests in the application. Deploy the unit tests by using the amplify push command in the Amplify CLI.
Add a test phase to the amplify.yml build settings for the application.
Add a test phase to the aws-exports.js file for the application.
Explanations:
Theamplify add testcommand is not a valid command in the Amplify CLI. Amplify CLI does not have a built-in command specifically for adding tests directly to an application.
Unit tests are important, but deploying unit tests viaamplify pushis not the proper approach. Unit tests should be run locally or in a CI/CD pipeline, not directly pushed through Amplify Hosting.
Adding a test phase to theamplify.ymlbuild settings allows you to integrate end-to-end testing during the build process, which ensures bugs can be identified before deployment. This is the correct way to implement testing in Amplify Hosting.
Theaws-exports.jsfile is used for configuring AWS services in the application. It is not meant to store or handle test-related code or logic. Tests should not be added here.
