Additional test methods are required for
javax.wsdl.PortType.getOperation and removeOperation.
The existing test method specifies an operation name
and null values for the input and output message name
arguments. To fully test the expected behaviour as
described in the API Javadoc for these methods, two
further test methods are required - one to test for a
named operation with named input and output messages
and another to test for a named operation with unnamed
input and output messages (i.e. with ":none" specified
for the input and output message name arguments).
