Reload the context::

    >>> User = Model.get('res.user')
    >>> Group = Model.get('res.group')
    >>> config._context = User.get_preferences(True, config.context)

    >>> sale_user.login = 'sale'
    >>> sale_user.main_company = company
    >>> sale_group, = sale_user.groups.find([('name', '=', 'Sales')])
    >>> sale_user.groups.append(sale_group)

Create stock user::

    >>> stock_user = User()

    >>> stock_user.login = 'stock'
    >>> stock_user.main_company = company
    >>> stock_group, = Group.find([('name', '=', 'Stock')])
    >>> stock_user.groups.append(stock_group)
    >>> stock_user.save()

Create fiscal year::

    >>> FiscalYear = Model.get('account.fiscalyear')
    >>> Sequence = Model.get('ir.sequence')
    >>> SequenceStrict = Model.get('ir.sequence.strict')
    >>> fiscalyear = FiscalYear(name=str(today.year))

    >>> fiscalyear.in_credit_note_sequence = invoice_seq
    >>> fiscalyear.save()
    >>> FiscalYear.create_period([fiscalyear.id], config.context)

Create chart of accounts::

    >>> AccountTemplate = Model.get('account.account.template')
    >>> Account = Model.get('account.account')
    >>> account_template, = AccountTemplate.find([('parent', '=', None)])
    >>> create_chart = Wizard('account.create_chart')

    >>> receivable, = Account.find([
    ...         ('kind', '=', 'receivable'),
    ...         ('company', '=', company.id),
    ...         ])
    >>> payable, = Account.find([
    ...         ('kind', '=', 'payable'),
    ...         ('company', '=', company.id),
    ...         ])
    >>> revenue, = Account.find([
    ...         ('kind', '=', 'revenue'),
    ...         ('company', '=', company.id),
    ...         ])
    >>> expense, = Account.find([
    ...         ('kind', '=', 'expense'),
    ...         ('company', '=', company.id),
    ...         ])
    >>> create_chart.form.account_receivable = receivable
    >>> create_chart.form.account_payable = payable
    >>> create_chart.execute('create_properties')

Create parties::

    >>> Party = Model.get('party.party')
    >>> customer = Party(name='Customer')
    >>> customer.save()
    >>> customer_grouped = Party(name='Customer Grouped',
    ...     sale_shipment_grouping_method='standard')
    >>> customer_grouped.save()

Create product::

    >>> ProductUom = Model.get('product.uom')
    >>> unit, = ProductUom.find([('name', '=', 'Unit')])
    >>> ProductTemplate = Model.get('product.template')
    >>> Product = Model.get('product.product')
    >>> product = Product()
    >>> template = ProductTemplate()
    >>> template.name = 'product'
    >>> template.default_uom = unit
    >>> template.type = 'goods'
    >>> template.purchasable = True
    >>> template.salable = True
    >>> template.list_price = Decimal('10')
    >>> template.cost_price = Decimal('5')
    >>> template.cost_price_method = 'fixed'
    >>> template.account_expense = expense
    >>> template.account_revenue = revenue
    >>> template.save()
    >>> product.template = template
    >>> product.save()

Create payment term::

    >>> PaymentTerm = Model.get('account.invoice.payment_term')
    >>> PaymentTermLine = Model.get('account.invoice.payment_term.line')
    >>> payment_term = PaymentTerm(name='Direct')
    >>> payment_term_line = PaymentTermLine(type='remainder', days=0)
    >>> payment_term.lines.append(payment_term_line)
    >>> payment_term.save()

Create an inventory::

    >>> config.user = stock_user.id
    >>> Inventory = Model.get('stock.inventory')
    >>> InventoryLine = Model.get('stock.inventory.line')
    >>> Location = Model.get('stock.location')
    >>> storage, = Location.find([
    ...         ('code', '=', 'STO'),
    ...         ])
    >>> inventory = Inventory()
    >>> inventory.location = storage
    >>> inventory_line = inventory.lines.new()
    >>> inventory_line.product = product
    >>> inventory_line.quantity = 100.0
    >>> inventory_line.expected_quantity = 0.0
    >>> inventory.click('confirm')
    >>> inventory.state
    u'done'

Sell some products::

    >>> config.user = sale_user.id
    >>> Sale = Model.get('sale.sale')
    >>> sale = Sale()
    >>> sale.party = customer
    >>> sale.payment_term = payment_term
    >>> sale.invoice_method = 'order'
    >>> sale_line = sale.lines.new()
    >>> sale_line.product = product
    >>> sale_line.quantity = 2.0
    >>> sale.click('quote')
    >>> sale.click('confirm')
    >>> sale.click('process')
    >>> sale.state
    u'processing'

Make another sale::

    >>> sale = Sale(Sale.copy([sale.id], config.context)[0])
    >>> sale.click('quote')
    >>> sale.click('confirm')
    >>> sale.click('process')
    >>> sale.state
    u'processing'

Check the shipments::

    >>> config.user = stock_user.id
    >>> ShipmentOut = Model.get('stock.shipment.out')
    >>> shipments = ShipmentOut.find([('customer', '=', customer.id)])
    >>> len(shipments)
    2
    >>> for shipment in shipments:
    ...     _ = ShipmentOut.assign_try([shipment.id], config.context)
    ...     shipment.click('pack')
    ...     shipment.click('done')

Now we'll use the same scenario with the grouped customer::

    >>> config.user = sale_user.id
    >>> sale = Sale()
    >>> sale.party = customer_grouped
    >>> sale.payment_term = payment_term
    >>> sale.invoice_method = 'order'
    >>> sale_line = sale.lines.new()
    >>> sale_line.product = product
    >>> sale_line.quantity = 1.0
    >>> sale.click('quote')
    >>> sale.click('confirm')
    >>> sale.click('process')
    >>> sale.state
    u'processing'

Make another sale::

    >>> sale = Sale()
    >>> sale.party = customer_grouped
    >>> sale.payment_term = payment_term
    >>> sale.invoice_method = 'order'
    >>> sale_line = sale.lines.new()
    >>> sale_line.product = product
    >>> sale_line.quantity = 2.0
    >>> sale.click('quote')
    >>> sale.click('confirm')
    >>> sale.click('process')
    >>> sale.state
    u'processing'

Check the shipments::

    >>> config.user = stock_user.id
    >>> shipments = ShipmentOut.find([
    ...     ('customer', '=', customer_grouped.id),
    ...     ('state', '=', 'waiting'),
    ...     ])
    >>> len(shipments)
    1
    >>> shipment, = shipments
    >>> len(shipment.outgoing_moves)
    2
    >>> sorted([m.quantity for m in shipment.outgoing_moves])
    [1.0, 2.0]
