### Question:
InsituReader extends NetcdfReader { @Override public GeoCoding getGeoCoding(int recordNo) throws IOException { return null; } InsituReader(String sensorName); @Override void open(DataFile datafile, File archiveRoot); @Override void close(); @Override int getNumRecords(); @Override InsituObservation readObservation(int recordNo); @Override List<SamplingPoint> readSamplingPoints(); @Override final Array read(String role, ExtractDefinition extractDefinition); @Override GeoCoding getGeoCoding(int recordNo); @Override double getDTime(int recordNo, int scanLine); @Override long getTime(int recordNo, int scanLine); @Override InsituSource getInsituSource(); @Override String getDatasetName(); @Override int getScanLineCount(); @Override int getElementCount();  }### Answer:
@Test public void testGetGeoCoding() throws IOException { final InsituReader reader = new InsituReader("whatever"); assertNull(reader.getGeoCoding(34)); }
