Answer 1

Mock<IUsers> _mockUserRepository = new Mock<IUsers>();
        _mockUserRepository.Setup(mr => mr.Update(It.IsAny<int>(), It.IsAny<string>()))
                            .Callback((int id, string name) =>
                                {
                                    //Your callback method here
                                });
 //check to see how many times the method was called
 _mockUserRepository.Verify(mr => mr.Update(It.IsAny<int>(), It.IsAny<string>()), Times.Once());

Answer 2

If you just want to verify this method is called, you should use Verifiable() method.

_mockUserRepository.Setup(mr => mr.Update(It.IsAny<int>(), It.IsAny<string>()))
                   .Verifiable();

If you also want to do something with those parameters, use Callback() first.

_mockUserRepository.Setup(mr => mr.Update(It.IsAny<int>(), It.IsAny<string>()))
                   .Callback((int id, string lastName) => {
                       //do something
                       }).Verifiable();

Update

Here's how you should mock it if you return a bool value as result.

_mockUserRepository.Setup(mr => mr.Update(It.IsAny<int>(), It.IsAny<string>()))
                   .Returns(true);
