Create carriers::

Sale products with cost on shipment::

    >>> sale = Sale()
    >>> sale.party = customer
    >>> sale.carrier = carrier1
    >>> sale.invoice_method = 'shipment'

    >>> sale.untaxed_amount
    Decimal('205.00')
    >>> len(sale.lines)
    3
    >>> sale.click('confirm')
    >>> sale.click('process')
    >>> sale.click('process')
    >>> sale.state
    'processing'

Check shipment::

    >>> shipment, = sale.shipments
    >>> shipment.carrier == carrier1
    True
    >>> shipment.cost_used
    Decimal('2.0000')
    >>> shipment.cost_sale_used
    Decimal('3.0000')

    >>> carriage, = shipment.before_carriages
    >>> carriage.carrier == carrier2
    True

    >>> carriage.cost_sale_used
    Decimal('2.0000')

Send products::

    >>> shipment.click('assign_force')
    >>> shipment.click('pick')
    >>> shipment.click('pack')
    >>> shipment.click('done')
    >>> shipment.state
    'done'

    >>> shipment.cost_invoice_line.amount
    Decimal('3.00')
    >>> carriage, = shipment.before_carriages
    >>> carriage.cost_invoice_line.amount
    Decimal('2.00')

Check customer invoice::

    >>> sale.reload()
