Autofixture: Using AutoMoqCustomization & SetupAllProperties to have all properties of a mocked interface fillled?

Question

I am trying to get Autofixture to setup and create me an anonymous of an interface. I am using the AutoMoqCustomization, but I keep getting an error.

My code is

var configuration = fixture.CreateAnonymous<Mock<IConfiguration>>();

Mock.Get(configuration).SetupAllProperties();

It actually errors on the SetupAllProperties with

System.ArgumentException : Object instance was not created by Moq. Parameter name: mocked

Anyone know what I am doing wrong?

Answer 1

You're trying to get a Mock<IConfiguration> from a Mock<IConfiguration> instance, which is hardly necessary. Just use

var configuration = fixture.CreateAnonymous<Mock<IConfiguration>>();

configuration.SetupAllProperties();
