How to integration test for cloudfront distrubtion?

[helbing]

I use CDK to deploy S3 static website which forwards a CloudFront. I want to use @aws-cdk/integ-tests-alpha for writing integration tests, but it didn't have any apis for the HTTP test. So how could I integration test it? I have to test it manually now, just like:

https://docs.aws.amazon.com/AmazonCloudFront/latest/DeveloperGuide/distribution-web-testing.html

It really depends on how you'd like to design your integration testing.

In AWS CDK, we typically use @aws-cdk/integ-tests to compare the synth results with pre-generated snapshots as described here so when you run yarn integ it will first compare the pre-generated snapshots. If it doesn't match, yarn integ will deploy the stack and re-generate the snapshots for you if the deployment succeeds.

However, in some cases you probably would like to design a more complicated test case for your CloudFront distribution. For example, to provisioning a CloudFront distribution with S3 static website as its backend and eventually create a custom resource probe like the Pinger to perform HTTP GET against the CloudFront endpoint and validate its response, which is still possible and in fact aws-eks has a similar integ test like this here.

And in case you miss it, cdk-http-pinger might be something you will be interested to help you perform HTTP request against the CloudFront endpoint as well.

Hope it helps!
