Am I right in saying with the SDF webstorm plugin, I can test functions such as getSublisValue against the XML representation of a record?

No, but have a look at the unit testing framework https://github.com/oracle/netsuite-suitecloud-sdk/blob/master/packages/unit-testing

@michoel We're not currently using the Oracle testing framework - looks like it provides a nice structured way to stub records though.

@Craig No, the XML framework is just for the metadata representation of a record/field/object. It's not used to interact or define instances of a record
