### Question:
NullTypeNode extends VariantTypeNode { public NullTypeNode(BinaryReader binaryReader, ChunkHeader chunkHeader, BxmlNode parent, int length) throws IOException { super(binaryReader, chunkHeader, parent, length); } NullTypeNode(BinaryReader binaryReader, ChunkHeader chunkHeader, BxmlNode parent, int length); @Override String getValue();  }### Answer:
@Test public void testNullTypeNode() throws IOException { assertEquals("", new NullTypeNode(testBinaryReaderBuilder.build(), chunkHeader, parent, -1).getValue()); }
