aws-cdk-lib/assertions: Cannot run testing against ProductStack objects

[thebillest]

Describe the bug

When trying to perform testing with cdk-nag, according to the methodology listed on this AWS blog, it fails if the stack passed into Annotations.fromStack() is a ProductStack.

Expected Behavior

The expectation would be that the test would pass/fail based on the CDK-Nag output/findings.

Current Behavior

The mentioned code will fail with an error similar to: Unable to find artifact with id "TestStackTestProductStack

Reproduction Steps

import { Annotations, Match } from 'aws-cdk-lib/assertions';
import { App, Aspects, Stack } from 'aws-cdk-lib';
import { AwsSolutionsChecks } from 'cdk-nag';
import { CdkTestProductStack } from '../lib/cdk_test-product-stack';

describe('cdk-nag AwsSolutions Pack', () => {
  let productStack: ProductStack;
  let stack: Stack;
  let app: App;
  // In this case we can use beforeAll() over beforeEach() since our tests 
  // do not modify the state of the application 
  beforeAll(() => {
    // GIVEN
    app = new App();
    stack = new Stack(app, 'test-stack');
    productStack = new CdkTestProductStack(stack, 'test-productStack');

    // WHEN
    Aspects.of(app).add(new AwsSolutionsChecks());
  });

  // THEN
  test('No unsuppressed Warnings', () => {
    const warnings = Annotations.fromStack(productStack).findWarning(
      '*',
      Match.stringLikeRegexp('AwsSolutions-.*')
    );
    expect(warnings).toHaveLength(0);
  });

  test('No unsuppressed Errors', () => {
    const errors = Annotations.fromStack(productStack).findError(
      '*',
      Match.stringLikeRegexp('AwsSolutions-.*')
    );
    expect(errors).toHaveLength(0);
  });
});

Unfortunately we can't help you debug this with the given code. I am moving this to discussion for general guidance. We probably need more details before we can address this issue.
