Use TestContainers for test suite

[jakoss]

I see that you have pretty large and complex test suite, hard to run locally since you would need to run providers/databases required. In our projects we are using TestContainers for .NET: https://dotnet.testcontainers.org

This simplifies every test that relies on some resource that can be run on docker. It automatically runs required resource using dotnet test, spins up all instances you need and after that - cleans up existing containers. Running all tests locally requires just one thing - docker. So far this was a gamechanger for our flow.

We have docker-compose file for that, so it should be pretty easy to run it, but to all test are going to work with container, specially the cloud provide test (AWS and Azure).

I have preference to use Aspire, after V10 is release we can take a look at test with Aspire

We currently use both - TestContainers and Aspire integration tests. And i think those live on a different level.

Aspire tests are more e2e. Infra setup takes quite some time, it's harder to access and clear databases between invocations etc. But you can test interactions between multiple pieces of your distributed system.

On the other hand - using TestContainers you can spin up as much throwaway databases/brokers as you need. It's easy and fast. So it's closer to unit/integration tests
