-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
+Code should always set a variable named `result` with the result of your test, that can be a list or
+a dictionary. If `result` is an empty list, it means that the test was succesful. Otherwise it will
+try to translate and print what is inside `result`.
+
+If the result of your test is a dictionary, you can set a variable named `column_order` to choose in
+what order you want to print `result`'s content.
+
+Should you need them, you can also use the following variables into your code:
+    * cr: cursor to the database
+    * uid: ID of the current user
+
+In any ways, the code must be legal python statements with correct indentation (if needed).
 
 Example: 
-sql = 'select id, name, ref, date from account_move_line where account_id in
