 Modify the Build Stage to Add a Test Action with a RunOrder Value of 2:

The build stage in AWS CodePipeline can have multiple actions. By adding a test action with a runOrder value of 2, the test action will execute after the initial build action completes.

 Use AWS CodeBuild as the Action Provider to Run Unit Tests:

AWS CodeBuild is a fully managed build service that compiles source code, runs tests, and produces software packages.

Using CodeBuild to run unit tests ensures that the tests are executed in a controlled environment and that only the code changes that pass the unit tests proceed to the deploy stage.

Example configuration in CodePipeline:

{

"name": "BuildStage",

"actions": [

{

"name": "Build",

"actionTypeId": {

"category": "Build",

"owner": "AWS",

"provider": "CodeBuild",

"version": "1"

},

"runOrder": 1

},

{

"name": "Test",

"actionTypeId": {

"category": "Test",

"owner": "AWS",

"provider": "CodeBuild",

"version": "1"

},

"runOrder": 2

}

]

}

By integrating the unit tests into the build stage and ensuring they run after the build process, the pipeline guarantees that only code changes passing all unit tests are deployed.
