This code throws an unexpected ArgumentOutOfRangeException

Hi Neil,

There is a issue in the test - you haven't specified were 'x' is being used in the method call - and as a consequence Isolator does not know that the parameter passed to the method is actually x.

The test should be:

[TestClass, Isolated] 
public class Tests 
{ 
   public class A 
   { 
      public void Method(int x) 
      { 
      } 
   } 

   [TestMethod] 
   public void Test() 
   { 
      A a = new A(); 
      Isolate.WhenCalled((int x) => a.Method(x)) 
         .AndArgumentsMatch((int x) => x == 1).IgnoreCall(); 
   } 
}

As you can see by replacing default(int) with x makes the test pass.

I agree we need to improve the error message.

Thanks Dror.
