Using Moq to Stub an interface method
.net, c#, moq, stub, unit-testing
Solution
Set up the stub like this:
var calendarServiceStub = new Mock<ICalenderService>();
calendarServiceStub
.Setup(c => c.Adjust(It.IsAny<DateTime>(), It.IsAny<BusinessDayConvention>(), It.IsAny<List<HolidayCity>>()))
.Returns(theDateTimeResultYouWant);
Pass `calendarServiceStub.Object` to the other class's constructor.
Problem
Possible Duplicate: How to mock a method that returns an int with MOQ Here's my interface: ``` public interface ICalenderService { DateTime Adjust(DateTime dateToAdjust, BusinessDayConvention convention, List<HolidayCity> holidayCities); } ``` I've done some research and it seems you can mock this real easily, but I want to stub this out using Moq so that I can pass the stub into my other class constuctors and have the stub return whatever `DateTime` I want for its `Adjust` method. What's the easiest way to do this? Edit: I know I can create my own stub in my project, but I'd like to write less code, and I think Moq can let me do that, I just don't know what the syntax looks like.
