Code should always return a result value. If result is an empty list, it means that
the test is succesful. Otherwise it will print what is inside result.
Code must be python with correct indentation (if needed).
Here is a list of function that you can use in your test :
 - group(lst, col) : 
 - reconciled_inv() : return the list of all reconciled invoices
 - get_parent(acc_id) : get parent analytical account
 - now() : return current datetime

Example: 
sql = 'select id, name, ref, date from account_move_line where account_id in 
(select id from account_account where type = 'view')'
cr.execute(sql)
result = cr.dictfetchall()
                                    </pre>
                                </group>
                            </page>
