Open statements for current device::

    >>> Statement = Model.get('account.statement')

    >>> open_statment.form.result == 'Statement Default opened.'
    True
    >>> payment_statement, = Statement.find([('state', '=', 'draft')])

When the sale is paid moves and invoices are generated::

    >>> pay_sale = Wizard('sale.payment', [sale])
    >>> pay_sale.execute('pay_')
    >>> payment_statement.reload()
    >>> sale.reload()
    >>> len(sale.shipments), len(sale.invoices), len(sale.payments)
    (0, 1, 1)

Stock moves should be created for the sale::

    >>> move, = sale.moves
    >>> move.quantity
    2.0
    >>> move.product == product
    True
    >>> move.state == 'done'
    True

An invoice should be created for the sale::

    >>> invoice, = sale.invoices
    >>> invoice.state == 'posted'
    True
    >>> invoice.untaxed_amount
    Decimal('20.00')
    >>> invoice.tax_amount
    Decimal('2.00')
    >>> invoice.total_amount
    Decimal('22.00')

When the statement is closed the invoices are paid and sale is done::

    >>> close_statment = Wizard('close.statement')
    >>> close_statment.execute('validate')
    >>> close_statment.form.result == 'Statement Default - Default closed.'
    True
    >>> payment_statement.reload()
    >>> payment_statement.state == 'validated'
    True
    >>> all(l.sale == sale for l in payment_statement.lines)
    True
    >>> payment_statement.balance
    Decimal('22.00')
    >>> sale.reload()
    >>> sale.paid_amount
    Decimal('22.00')
    >>> sale.residual_amount
    Decimal('0.00')
