c# - Mocking Interface as non-nullable instance with RhinoMocks -

i have written method suggested in https://stackoverflow.com/a/79903/976896. in short method accepts kind of enums argument , basic checking.

public void saveintvaluefromenum<t>(t value) t : struct, iconvertible {    if (!typeof(t).isenum)     {       throw new argumentexception("t must enumerated type");    }     this.intvalue = convert.toint32(value); } 

now want write test this, validates when non enum type feed it, exception thrown. wanted generate dummy object follow rhinomocks.

var mock = mockrepository.generatemock<iconvertible>(); 

but method doesn't accepts nullable type.

is there way mock structs/non-nullable instances rhinomocks?

edit: updated code listing
