Do i miss something here?

[rodrigovaras]

I have this:
public static class RpcProviderTestData
{
public static IEnumerable<TestDataRow<Func>> GetRpcContexts(){
}
}

Thsis does not seems to work:
[Test]
[MethodDataSource(typeof(RpcProviderTestData), nameof(RpcProviderTestData.GetRpcContexts))]
public async Task TestRequestAsync(IRpcContext rpcContext)

I tried other combinations like Func<TestDataRow< but the test harness does not add them

I think my previous explanation was too short, here is more detail:
public static class RpcTestData
{
public static IEnumerable<TestDataRow<Func>> GeRpcContexts()
{
yield return new(
() => new JsonRpcContext(),
DisplayName: "JsonRpc"
);
}
}

public class Foo
{
[Test]
[MethodDataSource(typeof(RpcTestData), nameof(RpcTestData.GeRpcContexts))]
public async Task TestRequestAsync(IRpcContext _)
{
await Task.Delay(500);
}
}

This does not build,
-> Attribute argument types 'Func' don't match method parameter types 'IRpcContext'

Changing to this:
public class Foo
{
[Test]
[MethodDataSource(typeof(RpcTestData), nameof(RpcTestData.GeRpcContexts))]
public async Task TestRequestAsync(Func _)
{
await Task.Delay(500);
}
}
give me this:
1>D:\teksoft\tek.shared.net\test\Rpc\Rpc.Contracts.Test\RpcMessageProviderTest.cs(16,63,16,76): error TUnit0046: Data source method should return Func for reference type parameters (other than string) to ensure proper test isolation

Can anybody clarify what is the right way to provide a TestDataRow that has 'DisplayName' ?

[rodrigovaras]

Apologies for my own confusion, figure out a way to make it work, for reference this is:
public static class RpcTestData
{
public static IEnumerable<Func<TestDataRow>> GeRpcContexts()
{
yield return () => new(new JsonRpcContext(), DisplayName: "JsonRpc");

}

}

public class Foo
{
[Test]
[MethodDataSource(typeof(RpcTestData), nameof(RpcTestData.GeRpcContexts))]
public async Task TestRequestAsync(IRpcContext _)
{
await Task.Delay(500);
}
}
