Exam DOP-C02 Topic 4 Question 352 Discussion

* 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.
