Feature request: AWS.Messaging.Testing package

[JanHyka]

Describe the feature

Introduce a package with tooling that allows for easy testing with AWS.messaging flows - from having payload enqueued all the way to consumption in handler.

Use Case

Writing fast and simple test for flows in messaging (ie from enqueued event to consumption in your handler) is possible, but not really trivial unless you have good knowledge of event structures... and requires a bit of boilerplating. Having testing toolkit should make it easier for everyone to use.

Proposed Solution

Introduce .Testing package that allows easy to use setup to test your AWS.messaging flows without necessity to connect to real SQS.

This could be just set of methods that will help you configure aws.messaging to local mock endpoint + EventMock< T> sort of wrapper for adding proper envelopes... Or go all the way including wiremock or similar to mock entire SQS and just use service collection extension method to inject it for testing scenarios.

Other Information

This is early idea that would require proper feature list (wishlist) for desired functionality before design and implementation.

This would be really cool.

Just an option for you if you are using SNS & SQS and want something that works in memory, I wrote a library that mocks those services, and try to pair to to the AWS behaviour as close as possible for general purpose messaging scenarios:
