We were supplied a class by a vendor that works successfully on our sandbox. This was created by generating the WSDL.  I am having all sorts of trouble sending this to production as this dramatically drops our code coverage.  The bulk of the class is just defining variables. 

Is there a way that anyone has come across to test these string declarations? 

If this helps, this is called by another class that sends the information to web service. Obviously, the other class that calls this fails as well.
