Hi Hong,
How can I use the class AddressTest?
Do I need to instantiate a new object from this class?
Do you have a demo using demographic package??
Tks

Hi Moraes,
I am not sure which AddressTest are you talking about. Can you be more specific?
To be honest, I haven't done much regarding demographic classes myself.
Regards,
Rong

Hi Rong,
I am not sure how can I use the classes inside the packages (Test Packages). For example in java ADL Parser project there are lots of classes inside the package (se.acode.openehr.parser) like ArchetypeValidatorTest.java but those classes doesn't have the main method to execute and test the sample.
In this case, do I need the create another classes (with the main method) to test then?

You could do that, but normally one would use JUnit to launch these testcases.
