Ephemeral test environment

[npalm]

Problem

Merging PR's requires in most cases manual work. By deploying the PR and running a few test to check the change is working and not breaking the module. For the lambda's we have a good set of automated tests, but for the full module (including IaC) this is still missing.

Steps to test a change

In general, we test a change as follow.

• set git ref to main
• build lambda's
• deploy examples. Typically mult-runner and or default (depending on the change)
• point git to the PR
• rebuild lambda's
• deploy, main reason is to check the PR is not breaking a current deployment
• run test based on a sample workflow and verify
• destroy environment

Notes

• Used Terratest back in the days for another project
• Maybe new terraform test capabilites are an option
• Having a script to run could be a good first step to automate
• Challenge is how to ensure the AWS account remains safe when verifying PR's. Manual approval could be required.
• Any help is welcome!
