Hi

I am trying to build some test for my Umbraco site.

I created a document type with 5 new properties. All is running as i would expect it to run.

I now add the below code for testing

 var pp = new Mock<IPublishedProperty>();
 var pub = new Mock<IPublishedContent>();

 pub.Setup(x => x.Name).Returns("Test");
 pub.Setup(x => x.Id).Returns(1234);

 pp.Setup(x => x.Alias).Returns("CustomerName");
 pp.Setup(x => x.Alias).Returns("Age");
 pp.Setup(x => x.GetValue(It.IsAny<string>(), It.IsAny<string>())).Returns("My Customer");
 pub.Setup(x => x.GetProperty("customerName")).Returns(pp.Object);
 pub.Setup(x => x.GetProperty("age")).Returns(pp.Object);

 var cust = new Customer(pub.Object, _publishedFallbackValue.Object);

myService.CallMethod(cust);

When it goes into the CallMethod in myService (which expects an IPublishedContent which is then casted), it throws the error

System.TypeInitializationException: 'The type initializer for 'Umbraco.Extensions.FriendlyPublishedContentExtensions' threw an exception.' ArgumentNullException: Value cannot be null. ArgParamNameName

Ive tried various changes and have seen some threads here but non work. Any pointers on what im missing?
