Each supported protocol is [listed here](https://smithy.io/2.0/aws/protocols/index.html). These tests are safe to run as they do not call real AWS services. You can run these tests by either opening the solution file and running the tests or via the `dotnet` cli by invoking `dotnet test AWSSDK.ProtocolTests.NetStandard.csproj`. The structure for the protocol test cases can be found [here in the smithy docs](https://smithy.io/2.0/additional-specs/http-protocol-compliance-tests.html).
