### Question:
TransFileListener implements FileListener { public String getRootNodeName() { return "transformation"; }  boolean open( Node transNode, String fname, boolean importfile ); boolean save( EngineMetaInterface meta, String fname, boolean export ); void syncMetaName( EngineMetaInterface meta, String name ); boolean accepts( String fileName ); boolean acceptsXml( String nodeName ); String[] getFileTypeDisplayNames( Locale locale ); String getRootNodeName(); String[] getSupportedExtensions();  }### Answer:
@Test public void testGetRootNodeName() throws Exception { assertEquals( "transformation", transFileListener.getRootNodeName() ); }
