How to use the MOQ library to mock an ENum

c#, enums, mocking, moq

Solution

This error means that your HasPermission method on PermissionService must be virtual, like so:

public virtual bool HasPermission(string name, PermissionType type)
{
   // logic
}

Problem

I am having an issue using the Moq library to mock an Enum within my project. I am trying to test a class and one of the methods accepts an ENum. Is there any way to do this? Here is the Enum I am trying to mock: ``` public enum PermissionType { Create = 0, Read = 1, Update = 2, Delete = 3, } ``` Here is the code I am trying to use to create the mock: ``` private static Mock<PermissionService> GetMockPermissionService(bool hasPermissions) { var mockPermissionService = new Mock<PermissionService>(); mockPermissionService.Setup(x => x.HasPermission(It.IsAny<string>(), **It.IsAny<PermissionType>()**)).Returns(hasPermissions); return mockPermissionService; } ``` This is the error I receive: System.ArgumentException: Invalid setup on a non-overridable member: x => x.HasPermission(It.IsAny(), It.IsAny()) I have also tried: ``` mockPermissionService.Setup(x => x.HasPermission(It.IsAny<string>(), **It.IsAny<int>()**)).Returns(hasPermissions); mockPermissionService.Setup(x => x.HasPermission(It.IsAny<string>(), **PermissionType.Read**)).Returns(hasPermissions); ``` Any help would be appreciated...
