-Any kind of attributes or member functions may be added to the Test Port. A selectable channel, which you communicate on, is almost always necessary. Names not interfering with the identifiers generated by the Java code generator can be used in the java file (for example, the names containing one underscore character). Avoid using static variables because you may get confused when more than one instances of the Test Port run simultaneously. Any kind of software libraries may be used in the Test Port as well.
