### Question:
SpotDimapMetadata extends XmlMetadata { @Override public String[] getRasterFileNames() { if (rootElement == null) { return null; } String path = null; MetadataElement currentElement; if (((currentElement = rootElement.getElement(SpotConstants.TAG_DATA_ACCESS)) != null) && ((currentElement = currentElement.getElement(SpotConstants.TAG_DATA_FILE)) != null) && ((currentElement = currentElement.getElement(SpotConstants.TAG_DATA_FILE_PATH)) != null)) { path = currentElement.getAttributeString(SpotConstants.ATTR_HREF); } else { logger.warning(String.format(MISSING_ELEMENT_WARNING, SpotConstants.TAG_DATA_FILE_PATH)); } return (path != null ? new String[]{path.toLowerCase()} : null); } SpotDimapMetadata(String name); @Override String getFileName(); @Override String getProductName(); String getProductDescription(); @Override String getFormatName(); @Override String getMetadataProfile(); @Override int getRasterWidth(); @Override int getRasterHeight(); @Override String[] getRasterFileNames(); @Override ProductData.UTC getProductStartTime(); @Override ProductData.UTC getProductEndTime(); String[] getBandNames(); String[] getBandUnits(); @Override int getNumBands(); int getNoDataValue(); Color getNoDataColor(); int getSaturatedPixelValue(); Color getSaturatedColor(); float getWavelength(int bandIndex); float getBandwidth(int bandIndex); ProductData.UTC getCenterTime(); TiePoint[] getTiePoints(); InsertionPoint getInsertPoint(); double getScalingFactor(int bandIndex); double getScalingOffset(int bandIndex); float getGain(int bandIndex); String getCRSCode(); double getOrientation(); Point2D.Float[] getCornerCoordinates(); HashMap<String, Double> getStatistics(int bandIndex); int getPixelDataType();  }### Answer:
@Test public void testGetRasterFileName() throws Exception { assertNotNull(metadata.getRasterFileNames()); assertEquals("mediumimage.tif", metadata.getRasterFileNames()[0]); }
