(integ-runner): (Snapshot serializer to ignore certain fields)

[webratz]

Describe the feature

The snapshots created by the integ-runner contain the full templates. There is certain fields that are changing (eg. tags, stack metadata, asset ids) that should not trigger a new test. In normal snapshots tests we use for example https://github.com/hupe1980/jest-cdk-snapshot to avoid adding these volatile fields to the snapshot, but I have found no way to do the same for integration tests.

Use Case

This feature would help us to avoid unneccessary re-runs of integration stacks for unrelated changes.

Proposed Solution

There already seems to be some logic for the template. A way to hook into that, or extending it, to cover use cases like ignoring metadata, assets or tags.

Yes I basically agree with you on this point. Feel free to submit your PR and the team would take a look when it's ready. Thank you.

Do you have any guidance on where would be a good place to implement this? Probably makes sense to briefly align on the basic structure before I have a closer look into this
