Amazon DOP-C02 Exam - Topic 6 Question 40 Discussion

Actual exam question for Amazon's DOP-C02 exam

Question #: 40
Topic #: 6

A software team is using AWS CodePipeline to automate its Java application release pipeline The pipeline consists of a source stage, then a build stage, and then a deploy stage. Each stage contains a single action that has a runOrder value of 1.

The team wants to integrate unit tests into the existing release pipeline. The team needs a solution that deploys only the code changes that pass all unit tests.

Which solution will meet these requirements?

AModify the build stage. Add a test action that has a runOrder value of 1. Use AWS CodeDeploy as the action provider to run unit tests.

BModify the build stage Add a test action that has a runOrder value of 2 Use AWS CodeBuild as the action provider to run unit tests

CModify the deploy stage Add a test action that has a runOrder value of 1 Use AWS CodeDeploy as the action provider to run unit tests

DModify the deploy stage Add a test action that has a runOrder value of 2 Use AWS CodeBuild as the action provider to run unit tests

Show Suggested Answer

Suggested Answer: B

* 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.

I’m surprised there’s even an option to test in the deploy stage!

Definitely not C, tests should be in the build stage, not deploy.

Wait, why would you add tests in the deploy stage? That seems risky.

Option B seems right, using CodeBuild for unit tests is standard.

I feel like the deploy stage isn't the right place for unit tests. It should be in the build stage, but I’m not sure if it should be runOrder 1 or 2.

I practiced a similar question where we had to integrate tests into a pipeline. I think modifying the build stage makes sense, but I can't recall if the runOrder should be 1 or 2.

I'm a bit unsure about whether to use CodeDeploy or CodeBuild for running unit tests. I feel like CodeBuild is more commonly used for that purpose.

I remember we discussed how the runOrder value affects the sequence of actions in the pipeline. I think adding a test action with a runOrder of 2 might be the right approach.

This seems like a tricky one, but I think I've got a handle on it. I'm leaning towards option B - adding the test action to the build stage with a runOrder of 2. That way, the build will happen first, and then the tests will run before the deployment.

I'm not sure about using CodeDeploy versus CodeBuild for the unit tests. I'll need to think through the pros and cons of each option to decide which one is the better fit.

Okay, I've got a strategy here. I think the best approach is to add the unit test action to the build stage, with a runOrder of 1. That way, the tests will run before the deployment, and only the passing code will get deployed.

Hmm, I'm a bit confused about the runOrder values and how that affects the order of the actions. I'll need to review that part of the question carefully.

This seems like a straightforward question. I think the key is to integrate the unit tests into the existing pipeline, and make sure they run before the deployment stage.

Definitely B. Running the tests in the build stage ensures that only the code that passes all the checks gets deployed. Can't afford any buggy releases, am I right?
