Is it not possible to test it with elasticmq?

Also, the CI is failing, please check linting and compile errors 🙏

[V-Lamp]

Tests with localstack pass in a few seconds and is the de facto standard in testing AWS, so happy to provide this instead (lower effort as I have it working) and will benefit other tests in here eventually 🙂

I will add the tests, and that will fix any issues, I just shared the idea to see if it indeed fits the needs of the use case before I progress further

[ghostdogpr]

I think it would be better for maintainability if all tests used the same backend (whether it's localstack or elasticmq) 😄

Regarding the original idea, I haven't used SQS since 2019 so I don't have much opinions on this anymore, I suggest you ask opinion on the zio Discord, there is a channel for zio-sqs and you might find other users there 👍

I have also left a comment in testcontainers-for-zio on this btw: scottweaver/testcontainers-for-zio#41 (comment)

I see what you mean, I would expect it to be easy to transition tests to localstack given that ultimately all that is needed is a Layer providing a zio.aws.sqs.Sqs

[V-Lamp]

I wanted to suggest this approach, where a new mock server is created, with a random port to allow for parallel testing.
The aws config and sqs client are made all together, so that tests just need this single layer and no setup within the tests themselves.
