Hi all, Is there a way to validate nullable reference types with Pact .NET? 🙂 If we have the following two classes:

public class ConsumerClass 
{
    public string MyProperty { get; init; }
}

public class ProviderClass 
{
    public string? MyProperty { get; init; }
}

and in my consumer test, I've set the following:

.WithJsonBody(Match.Type(new ConsumerClass { MyProperty = "test" }));

(since I don't want to validate the actual values) I'd expect the provider test to fail this, since I have marked

MyProperty

to be a nullable property.

Matchers aren’t there to describe how your Provider works, they are there to describe the scenarios a consumer needs, which is then checked against a provider

Thanks a lot for your answers, Matt 🙂 Greatly appreciated. It totally makes sense. It's not so much the property itself that makes sense to test, but rather the type. If I mark the string as nullable and set it's value to null on provider side, while the consumer expects it to be a string, the provider tests fails. That's exactly what I was after, first hand.

Perfect!
