How to Mock the ActivityContext Class

I wanted to mock the System.Activities.NativeActivityContext & System.Activities.ActivityContext for my unit test.

i.e.

using Moq;
using Autofac.Extras.Moq;

var executionContext = new Mock<NativeActivityContext>();

Since this class does not have zero parameter constructor, I’m unable to mock, neither not able to create object for this.

Note: Looks Like there is no constructor defined in this class

Can anyone help me how to mock or create object of this classes?
