### Question:
ExportCfgTask { public void setDestinationFolder(File destinationFolder) { this.properties.put(ExporterConstants.DESTINATION_FOLDER, destinationFolder); } ExportCfgTask(HibernateToolTask parent); Properties getProperties(); void setDestinationFolder(File destinationFolder); void setMetadataDescriptor(MetadataDescriptor metadataDescriptor); void setTemplatePath(Path path); void addConfiguredProperty(Variable variable); void execute();  }### Answer:
@Test public void testSetDestinationFolder() { ExportCfgTask ect = new ExportCfgTask(null); assertNull(ect.properties.get(ExporterConstants.DESTINATION_FOLDER)); File file = new File("/"); ect.setDestinationFolder(file); assertSame(file, ect.properties.get(ExporterConstants.DESTINATION_FOLDER)); }
