feat: Test Utils as part of the library

[FlorianWeissDev]

Description

I'm writing my own pack with a mix of custom rules and AWS rules. Now, I want to test these rules, and I've noticed that you've already written some utilities to make testing a little bit easier and better structured. Have you considered bundling these utilities with the library itself?

Use Case

Authors of custom cdk-nag-packs most likely want or need to test their rules.

Proposed Solution

Add existing utilities to the library.

• I may be able to implement this feature request
• This feature might incur a breaking change

I have not because the utils use old libraries and occasionally get refactored for new features. I don't want to break users when this happens

That would be also helpful for me. Could the util exported with a expermimental post fix or something else?
Otherwise I have to copy them from the library and watch for changes 😄

@JohannesKonings, I decided to use the Annotation Matching to test my rules. Maybe this is helpful for you as well.

Annotations.fromStack(stack).hasNoWarning('*', Match.stringLikeRegexp('.*MyRule.*'));
