Would be possible to use generics with MethodDataSource ?

[rodrigovaras]

This is the scenario I would like to refactor.
public class RpcContextTest
{
[Test]
public async Task TestJsonContext()
{
var jsonRpcContext = new JsonRpcContext();
jsonRpcContext.AddJsonNodeTypes();
await TestInternal(jsonRpcContext, false);
}

[Test]
public async Task TestProtoContext()
{
    var protoRpcContext = new ProtoRpcContext();
    protoRpcContext.AddProtoNodeTypes();
    await TestInternal(protoRpcContext, false);
}

private async Task TestInternal<TPayload>(IRpcContextPayloadConverter<TPayload> rpcContext, bool typeMatch)
{

...
}
}

Do your objects share a base type or interface?

I'm thinking something like:

  public class RpcContextTest
  {
      [Test]
      [MethodDataSource(nameof(GetContext))]
      public async Task TestContext(Context context)
      {
          await TestInternal(context, false);
      }

      public static IEnumerable<Func<Context>> GetContext()
      {
          yield return () => 
          {
               var jsonRpcContext = new JsonRpcContext();
               jsonRpcContext.AddJsonNodeTypes();
               return jsonRpcContext;
          };

          yield return () => 
          {
               var protoRpcContext = new ProtoRpcContext();
               protoRpcContext.AddProtoNodeTypes();
               return protoRpcContext;
          };
      }

      private async Task TestInternal<TPayload>(IRpcContextPayloadConverter<TPayload> rpcContext, bool typeMatch)
      {
          ...
      }
  }

Almost a derived interface but with some tweaks:
public interface IRpcContextPayloadConverter<> : IRpcContext, IRpcPayloadConverter<>
{
IRpcProvider CreateRpcProvider(IRpcDataProvider rpcDataProvider);
}

I'm returning a IRpcContext but the payload will be different in json (string) vs Proto(byte[]) hence the need of the generic test method
I get errors:
1>D:\teksoft\tek.shared.net\test\Rpc\Rpc.Contracts.Test\RpcContextTest.cs(41,23,41,41): error TUnit0300: Generic test method may require runtime type creation may not be AOT-compatible. All generic type combinations must be known at compile time.
1>D:\teksoft\tek.shared.net\test\Rpc\Rpc.Contracts.Test\RpcContextTest.cs(40,6,40,46): error TUnit0001: Attribute argument types 'IRpcContext' don't match method parameter types 'IRpcContextPayloadConverter'

public static IEnumerable<Func<TestDataRow>> GetRpcContexts()
{
yield return () =>
{
var jsonRpcContext = new JsonRpcContext();
jsonRpcContext.AddTypeInfoResolver(JsonContext.Default);
return new(jsonRpcContext, DisplayName: "Json rpc");
};
yield return () =>
{
var protoRpcContext = new ProtoRpcContext();
return new(protoRpcContext, DisplayName: "Proto rpc");
};
}

[Test]
[MethodDataSource(nameof(GetRpcContexts))]
public async Task TestInternal2Async<TPayload>(IRpcContextPayloadConverter<TPayload> _)
{
    await Task.Delay(100);
}
