Integration tests with CDK and Python

To serve as a guide to using integ-runner with your Python CDK projects.

Setup

This has a .devcontainer folder to allow you to use the Remote - Containers extension in VSCode to develop in a container. If you make use of this, you use the VS COde DevContainers extension to open the project in a container.

You'll need to authenticate with AWS in your preferred manner; either using an IAM key, or better, using aws-sso-util to assume a role through the IAM Identity Center.

Running the tests

To run the tests, you can use the following command:

integ-runner --update-on-failed

And, you should see the following output:
