When using AspNetCore I could not mock the ControllerContext since I got an exception.

Unsupported expression: m => m.HttpContext
Non-overridable members (here: ActionContext.get_HttpContext) may not be used in setup / verification expressions.

Instead I had to mock the HttpContext and create a ControllerContext and pass the HttpContext object along.

I did find that mocking claims or response/request objects works as well when using this method.

[Test]
public void TestSomeStuff() {
  var name = "some name";

  var httpContext = new Mock();
  httpContext.Setup(m => m.User.IsInRole("RoleName")).Returns(true);
  httpContext.Setup(m => m.User.FindFirst(ClaimTypes.Name)).Returns(name);

  var context = new ControllerContext(new ActionContext(httpContext.Object, new RouteData(), new ControllerActionDescriptor());

  var controller = new MyController()
  {
    ControllerContext = context
  };

  var result = controller.Index();
  Assert.That(result, Is.Not.Null);
}
