It is not possible to stub package usage for unit testing either using moq or shims

[CraigComeOnThisNameCantBeTaken]

I am trying to write unit tests around a class which uses the recurly client, however due to the internal constructors and internal methods, I cannot mock or shim the classes.

Example:

var fakeList = new ShimRecurlyList<Plan>();

Error:

Example:

var fakeList = new Mock<RecurlyList<Plan>>();
ShimPlans.List = () => fakeList.Object;

Exception:

System.ArgumentException
  HResult=0x80070057
  Message=Type to mock must be an interface, a delegate, or a non-sealed, non-static class.
  Source=Moq
  StackTrace:
   at Moq.CastleProxyFactory.CreateProxy(Type mockType, IInterceptor interceptor, Type[] interfaces, Object[] arguments)
   at Moq.Mock`1.InitializeInstance()
   at Moq.Mock`1.OnGetObject()
   at Moq.Mock.get_Object()
   at Moq.Mock`1.get_Object()
   at KeySystems.SubscriptionServiceTests.RecurlySubscriptionServiceTests.<>c__DisplayClass0_0.<AddPlans>b__1() in D:\KeySystems-CustomerService\KeySystems.SubscriptionServiceTests\RecurlySubscriptionServiceTests.cs:line 57

  This exception was originally thrown at this call stack:
    [External Code]

Inner Exception 1:
TypeLoadException: Method 'ReadXml' in type 'Castle.Proxies.RecurlyList`1Proxy' from assembly 'DynamicProxyGenAssembly2, Version=0.0.0.0, Culture=neutral, PublicKeyToken=null' does not have an implementation.

How should I test my code that relies on the recurly client as a dependency please?

Actually, I forgot, we are using API v2.
