@Test
public void testWrapper() throws Exception {
    Statement statement = getConnection().createStatement();
    ResultSet rs = statement.executeQuery(SQL_EMPS);

    assertTrue(rs.isWrapperFor(JcrResultSet.class));

    try {/*  www .j a v a2 s .c  o m*/
        rs.isWrapperFor(null);
        fail();
    } catch (IllegalArgumentException ignore) {
    }

    assertFalse(rs.isWrapperFor(QueryResult.class));

    JcrResultSet jrs = rs.unwrap(JcrResultSet.class);
    assertNotNull(jrs);

    int count = 0;

    while (jrs.next()) {
        ++count;

        Node node = jrs.getCurrentRow().getNode();

        String nodeName = node.getName();
        String nodePath = node.getPath();
        String nodeId = node.getIdentifier();
        double score = jrs.getCurrentRow().getScore();

        assertEquals("testdata-" + count, nodeName);
        assertEquals("/testdatafolder/" + nodeName, nodePath);
        assertTrue(nodeId != null && !nodeId.isEmpty());
        assertTrue(score > 0.0);

    }

    rs.close();
    statement.close();
