Hello  all,

I have use this code to convert amount to word in my invoice report in odoo 14 C, and it worked great! but now I wannt to do unit tests for this function "amount_to_text" . If you have any ideas how to do it , please help! 

Thank you.

This my python file including this function:

********************************

from odoo import fields, models


class InvoiceOrder(models.Model):
    _inherit = 'account.move'

    # @api.multi
    def _compute_amount_in_word(self):
        for rec in self:
            rec.num_word = str(rec.currency_id.amount_to_text(rec.amount_total))

    num_word = fields.Char(string="Amount In Words:", compute='_compute_amount_in_word')
