### Question:
IsBlankRow implements Predicate<Row> { public static final boolean isBlankRow(final Row row) { return isBlankRow.apply(row); } private  IsBlankRow(); static final boolean isBlankRow(final Row row); @Override boolean apply(final Row row); static final IsBlankRow isBlankRow; }### Answer:
@Test public void testAllBlankCellRow() { assertTrue(isBlankRow(allBlankCellRow)); }
@Test public void testEmptyRow() { assertTrue(isBlankRow(emptyRow)); }
@Test public void testDataRow() { assertFalse(isBlankRow(rowWithDataCell)); }
