### Question:
StructureBuilder { public abstract StructureBuilder addVC(String name);  static StructureBuilder getBuilder(); static StructureBuilder getBuilder(final Structure existingStructure); abstract Structure build(); abstract StructureBuilder addChar(String name, int length); abstract StructureBuilder addDQ8(String name); abstract StructureBuilder addDynamicList(String name, Structure structure); abstract StructureBuilder addF8(String name); abstract StructureBuilder addI2(String name); abstract StructureBuilder addI4(String name); abstract StructureBuilder addList(String name, Structure structure, int size); abstract StructureBuilder addRecord(String name, Structure structure); abstract StructureBuilder addStatusData(); abstract StructureBuilder addVC(String name);  }### Answer:
@Test public void testAddVC() { final String fieldName = "VC_FIELD"; builder.addVC(fieldName); validateField(builder.build(), fieldName, DataType.VC); }
