Mock Masstransit's GetRetryAttempt() using NSubstitute

I'm trying to mock Masstransit's GetRetryAttempt() method to return some values using NSubstitute but doesn't seems to be working. Not getting any errors but GetRetryAttempt() returns always 0 instead of 2.

Test

var context = Substitute.For<ConsumeContext<FakeCommand>>();
var consumeRetryContext = Substitute.For<ConsumeRetryContext>();
consumeRetryContext.RetryAttempt.Returns(2);
context.TryGetPayload(out consumeRetryContext).Returns(true);
context.GetRetryAttempt().Returns(consumeRetryContext.RetryAttempt);

Application code

public async Task Consume(ConsumeContext<T> context)
{
    ......
    var retryAttempt = context.GetRetryAttempt();
}

You didn't mock the retry context correctly. This works

var context = Substitute.For<ConsumeContext<FakeCommand>>();
var consumeRetryContext = Substitute.For<ConsumeRetryContext>();
consumeRetryContext.RetryAttempt.Returns(2);
context
   .TryGetPayload(out Arg.Any<ConsumeRetryContext>())
   .Returns(result =>
   {
       result[0] = consumeRetryContext;
       return true;
   });
