=============================

    >>> from proteus import Model
    >>> from trytond.modules.company.tests.tools import create_company
    >>> from trytond.tests.tools import activate_modules

Activate modules::

    >>> config = activate_modules('sale', create_company)

Create a party and set their default methods::

    >>> Party = Model.get('party.party')
    >>> customer = Party(name='Customer')
    >>> customer.sale_shipment_method = 'invoice'
    >>> customer.sale_invoice_method = 'shipment'

Create a sale to to check default methods::

    >>> Sale = Model.get('sale.sale')
    >>> sale = Sale()
    >>> sale.party = customer
    >>> sale.shipment_method
    'invoice'
    >>> sale.invoice_method
