NCrunch Unit testing code coverage

In my Visual Studio 2013 projects I am getting uncovered unit test warning from NCrunch where those functions have strong dependency to other entities. I would like to learn is there any natural way to clear out those warnings.

Lets assume I have a person class like this;

public class PersonApiHandler{    
public virtual Person GetPersonFromFacebook(){
// heavy facebook api call here
return person;    }
}

and I have a fake class like;

public class PersonApiHandlerFake: PersonApiHandler
{
public override Person GetPersonFromFacebook(){
// fake person is returning - isolated
return fakeUser;
}
}

then I am calling this method like;

    [TestFixture]
        public class PersonApiHandlerTests(){
    [Test]
    public void GetPerson_from_Api_success(){
    PersonApiHandlerFake fake = new PersonApiHandlerFake();
var fakeFacebookUser = fake.GetPersonFromFacebook();
Assert.IsNotNull(fakeFacebookUser );
    }

in this case NCrunch complains about PersonApiHandler.GetPersonFromFacebook is not code covered. Since this function calls real API, I cannot use it in my unit tests. Only way I found out using [ExcludeFromCodeCoverage] attribute to disable this warning. Is it right way to do or is there any other way to clear out uncovered code messages?

NCrunch supports the use of specific inline comments to select one or more lines of code it should ignore from coverage. You can use //ncrunch: no coverage start and //ncrunch: no coverage end to mark the beginning and end of the code block, or use //ncrunch: no coverage to ignore a single line of code.
