### Question:
ColumnPositionMappingStrategy extends HeaderColumnNameMappingStrategy<T> { public String[] getColumnMapping() { return columnMapping.clone(); }  void captureHeader(CsvReader reader); String[] getColumnMapping(); void setColumnMapping(String... columnMapping);  }### Answer:
@Test public void testGetColumnMapping() { String[] columnMapping = strat.getColumnMapping(); assertNotNull(columnMapping); assertEquals(0, columnMapping.length); String[] columns = new String[]{"name", "orderNumber", "id"}; strat.setColumnMapping(columns); columnMapping = strat.getColumnMapping(); assertNotNull(columnMapping); assertEquals(3, columnMapping.length); assertArrayEquals(columns, columnMapping); }
