Automated tests for Terraform CDK projects

Is there any example repo using terraform-cdk with tests? I was looking at terratest and was wondering if something like that is available when we are using the CDK.

Edit: I’m more curious about integration type tests that actually provisions the infrastructure. Not just snapshot tests.

I believe Terratest would work just fine. After synthesizing Terraform json, cdktf calls into regular Terraform cli.
You may be able to use the shell module to run cdktf synth and then use the regular Terraform module.
