ResolutionContext has no public constructor

[gauravpatni123]

I am unable to create instance of ResolutionContext as it is internal in updated version (I am in version 12.0) , so my question is how I can mock it like before (previously I was in version 8.0 ) , please see the below code snippet , any help on this will be appreciated .
Below is the code : -

public class JobServiceClientOfValueResolverTests
{
private ResolutionContext _resolutionContext;
private string _result;
private Resource _resource2;

    public JobServiceClientOfValueResolverTests() {
        _destination = new JobViewDto();
        //_resolutionContext = new ResolutionContext(
        //    new Mock<IMappingOperationOptions>().Object,
        //    new Mock<IRuntimeMapper>().Object
        //);
    }

    private void When_Mapped()
    {
        _result = new JobServiceClientOfValueResolver().Resolve(_source, _destination, _destination.ClientOf, _resolutionContext);
    }

}
