Deno CloudSpec AWS CDK Proof of Concept
This is a proof of concept for a Deno based cloudspec project. This will deploy an AWS CDK stack as part of the test and make expectations on the stack outputs. It's using the Deno testing capabilities.
Nb: As stated above, that's a POC and nothing I'd recommend using at the moment.
Motivation
Trying to find a streamlined experience for end2end testing, without having to deal with cumbersome test setup. Essentially aiming for a single command which works without much (any?) config. Deno became quite an attractive contender recently by adding direct support for NPM packges.
While that's still focused on Typescript as a language, I could imagine this would be an acceptable workflow for other jsii languages as well, since it's pretty much effortless and zero config. But that's something for another experiment.
Prerequisites
You'll need to have Deno installed
Examples
Inline Deno
This test demonstrates that it's possible to use AWS CDK inline in Deno tests.
deno test --no-check --allow-all ./examples/inline
Embedded into Node Project
This test demonstrates that it's possible to use Deno inside an Typescript / Node AWS CDK application. The way to make it work is to use an import_map to map the NPM packages. Potentially, this import map could be auto generated based on a package.json file to allow seamless test runs alongside an otherwise node based project.
deno test --no-check --allow-all --import-map ./examples/node/import_map.json ./examples/node
