    >>> kg, = ProductUom.find([('name', '=', 'Kilogram')])
    >>> template = ProductTemplate()
    >>> template.name = 'Product1'

Create sale blanket agreement::

    >>> blanket_agreement = SaleBlanketAgreement()
    >>> blanket_agreement.customer = customer
    >>> blanket_agreement.from_date = today
    >>> blanket_agreement.to_date = later
    >>> blanket_agreement_line = blanket_agreement.lines.new()

    >>> blanket_agreement_line.unit_price = Decimal('9.0000')
    >>> blanket_agreement.click('run')
    >>> blanket_agreement.state
    'running'

Create sale from blanket agreement::

    >>> create_sale = blanket_agreement.click('create_sale')
    >>> len(create_sale.form.lines)
    1
    >>> create_sale.form.lines[0].remaining_quantity
    20.0
    >>> create_sale.execute('create_sale')
    >>> sale, = create_sale.actions[0]

    >>> line, = sale.lines
    >>> assertEqual(line.product, product1)
    >>> line.quantity
    20.0
    >>> line.unit_price
    Decimal('9.0000')
    >>> line.quantity = 5.0
    >>> line.save()

    >>> blanket_agreement.reload()
    >>> blanket_agreement_line, = blanket_agreement.lines

    >>> sale.state
    'processing'

    >>> blanket_agreement_line.reload()
    >>> blanket_agreement_line.remaining_quantity
    15.0

    >>> blanket_agreement.click('draft')
    >>> line, = blanket_agreement.lines
    >>> line.product = product2
    >>> blanket_agreement.save()
    Traceback (most recent call last):

    >>> sale_line = sale.lines.new()
    >>> sale_line.product = product1
    >>> sale_line.unit_price
    Decimal('10.0000')
