Mock a lambda parameter in Moq

Question

I would like to mock this action in Moq:

Action<string, long> cursorPersister;

I have tried to implemented in this way:

var cursorPersister = new Mock<Action<string, long>>();
cursorPersister.Setup(cp => cp.Invoke(It.IsAny<string>(), It.IsAny<long>()));

cursorPersister.Verify();

However it does not work. Program freeze on the line where I call Setup(...). Anyone can explain this and offer an alternative approach?

Answer 1

Problem solved. Instead of

cursorPersister.Setup(cp => cp.Invoke(It.IsAny<string>(), It.IsAny<long>()));

Use

cursorPersister.Setup(cp => cp(It.IsAny<string>(), It.IsAny<long>()));

Answer 2

Just create a method with a string and long parameters and pass it instead of the mock. Why do you want to mock it?
