### Question:
ExportOptionsModel extends Observable { public void setIncludeMetaColumns(boolean includeMetaColumns) { boolean changed = myIncludeMetaColumns != includeMetaColumns; if (changed) { myIncludeMetaColumns = includeMetaColumns; setChanged(); notifyObservers(INCLUDE_META_COLUMNS_PROP); } }  List<ColorFormat> getColorFormats(); List<LatLonFormat> getLatLonFormats(); ColorFormat getSelectedColorFormat(); LatLonFormat getSelectedLatLonFormat(); boolean isAddWkt(); boolean isIncludeMetaColumns(); boolean isSelectedRowsOnly(); boolean isSeparateDateTimeColumns(); void setAddWkt(boolean addWkt); void setIncludeMetaColumns(boolean includeMetaColumns); void setSelectedColorFormat(ColorFormat selectedColorFormat); void setSelectedLatLonFormat(LatLonFormat selectedLatLonFormat); void setSelectedRowsOnly(boolean selectedRowsOnly); void setSeparateDateTimeColumns(boolean separateDateTimeColumns); static final String ADD_WKT_PROP; static final String INCLUDE_META_COLUMNS_PROP; static final String SELECTED_COLOR_FORMAT_PROP; static final String SELECTED_LAT_LON_FORMAT_PROP; static final String SELECTED_ROWS_ONLY_PROP; static final String SEPERATE_DATE_TIME_COLUMNS_PROP; }### Answer:
@Test public void testSetIncludeMetaColumns() { EasyMockSupport support = new EasyMockSupport(); Observer observer = createObserver(support, ExportOptionsModel.INCLUDE_META_COLUMNS_PROP); support.replayAll(); ExportOptionsModel model = new ExportOptionsModel(); model.addObserver(observer); assertFalse(model.isIncludeMetaColumns()); model.setIncludeMetaColumns(true); assertTrue(model.isIncludeMetaColumns()); support.verifyAll(); }
