Motivation

This PR fixes CRUD issue where an SQS ESM's batch size exceeding 10 elements raises an exception on polling.

Changes

  • Fixes bug when creating an SQS mapping that prevented a BatchSize of greater than 10 elements.

Testing

  • Added snapshot tests for varying batch sizes.

LGTM, thanks for providing a minimal fix and postponing the complete fix until after the next patch release!

Oh damn. That was a test file I created to mirror an SQS queue from 1 to another using ESM. Turned out to be overkill. Will remove this reference

What a small validation can all entail ... :)
Thanks for pushing testing coverage into more behavioral complex parity lands 🚀

nice coverage 💯

they took ~45s on my M1, but could be slower after we implement the window mechanism, hence it's good to adjust the window for LocalStack here 💡

nit: these refer to Lambda pollers I guess (also something we don't support in LS yet ;)

idea for future: It feels we re-implement this pattern all over the place in different ways and should consider using an appropriate helper/fixture 🙈
