Our language of choice is TypeScript. It is at the time of writing the only language that supports testing.1 Just for this fact alone, I would always recommend to treat TypeScript as the first choice when deciding on the CDK language and only use another language if you have strong reasons for it.

Lately, I have been using the AWS Cloud Development Kit (CDK) a lot to set up infrastructure on AWS, and I am so happy about the build-in test support. Not only did it save a lot of time already, but I also really like that there is now (finally) a way to actually document intent. In this article I want to share some of my learnings and findings with you about how to use the testing capabilities of the CDK.
