Imports::

    >>> import datetime
    >>> from dateutil.relativedelta import relativedelta
    >>> from decimal import Decimal
    >>> from operator import attrgetter
    >>> from proteus import config, Model, Wizard
    >>> today = datetime.date.today()

    ...         rounding=Decimal('0.01'), mon_grouping='[3, 3, 0]',
    ...         mon_decimal_point=',')

    >>> company_config.execute('company')
    >>> company = company_config.form
    >>> party = Party(name='Dunder Mifflin')
    >>> party.save()
    >>> company.party = party
    >>> company.currency = currency
    >>> company_config.execute('add')
    >>> company, = Company.find([])

Reload the context::

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

Create sale user::

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

Create account user::

    >>> account_user = User()
    >>> account_user.name = 'Account'
    >>> account_user.login = 'account'
    >>> account_user.main_company = company
    >>> account_group, = Group.find([('name', '=', 'Account')])
    >>> account_user.groups.append(account_group)
    >>> account_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.start_date = today + relativedelta(month=1, day=1)
    >>> fiscalyear.end_date = today + relativedelta(month=12, day=31)
    >>> fiscalyear.company = company
    >>> post_move_seq = Sequence(name=str(today.year), code='account.move',

    >>> invoice_seq = SequenceStrict(name=str(today.year),
    ...     code='account.invoice', company=company)
    >>> invoice_seq.save()
    >>> fiscalyear.out_invoice_sequence = invoice_seq
    >>> fiscalyear.in_invoice_sequence = invoice_seq
    >>> fiscalyear.out_credit_note_sequence = invoice_seq
    >>> 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')
    >>> create_chart.execute('account')
    >>> create_chart.form.account_template = account_template
    >>> create_chart.form.company = company
    >>> create_chart.execute('create_account')
    >>> 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_invoice_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()

Sale some products::

    >>> config.user = sale_user.id
    >>> Sale = Model.get('sale.sale')
    >>> SaleLine = Model.get('sale.line')
    >>> sale = Sale()
    >>> sale.party = customer
    >>> sale.payment_term = payment_term
    >>> sale.invoice_method = 'order'
    >>> sale_line = SaleLine()
    >>> sale.lines.append(sale_line)
    >>> sale_line.product = product
    >>> sale_line.quantity = 2.0
    >>> sale.save()
    >>> Sale.quote([sale.id], config.context)
    >>> Sale.confirm([sale.id], config.context)
    >>> Sale.process([sale.id], config.context)
    >>> sale.state
    u'processing'

Make another sale::

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

Check the invoices::

    >>> config.user = account_user.id
    >>> Invoice = Model.get('account.invoice')
    >>> invoices = Invoice.find([('party', '=', customer.id)])
    >>> len(invoices)
    2
    >>> invoice = invoices[0]
    >>> invoice.type
    u'out_invoice'
    >>> Invoice.post([invoice.id], config.context)
    >>> invoice.reload()
    >>> invoice.state
    u'posted'

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 = SaleLine()
    >>> sale.lines.append(sale_line)
    >>> sale_line.product = product
    >>> sale_line.quantity = 1.0
    >>> sale.save()
    >>> Sale.quote([sale.id], config.context)
    >>> Sale.confirm([sale.id], config.context)
    >>> Sale.process([sale.id], config.context)
    >>> sale.state
    u'processing'

Make another sale::

    >>> sale = Sale()
    >>> sale.party = customer_grouped
    >>> sale.payment_term = payment_term
    >>> sale.invoice_method = 'order'
    >>> sale_line = SaleLine()
    >>> sale.lines.append(sale_line)
    >>> sale_line.product = product
    >>> sale_line.quantity = 2.0
    >>> sale.save()
    >>> Sale.quote([sale.id], config.context)
    >>> Sale.confirm([sale.id], config.context)
    >>> Sale.process([sale.id], config.context)
    >>> sale.state
    u'processing'

Check the invoices::

    >>> config.user = account_user.id
    >>> invoices = Invoice.find([
    ...     ('party', '=', customer_grouped.id),
    ...     ('state', '=', 'draft'),
    ...     ])
    >>> len(invoices)
    1
    >>> invoice, = invoices
    >>> len(invoice.lines)
    2
    >>> invoice.lines[0].quantity
    1.0
    >>> invoice.lines[1].quantity
    2.0
    >>> Invoice.post([invoice.id], config.context)
    >>> invoice.reload()
    >>> invoice.state
    u'posted'

Create a manual invoice::

    >>> manual_invoice = Invoice()
    >>> manual_invoice.party = customer_grouped
    >>> manual_invoice.payment_term = payment_term
    >>> manual_invoice.save()

Check that a new sale won't be grouped with the manual invoice::

    >>> config.user = sale_user.id
    >>> sale = Sale()
    >>> sale.party = customer_grouped
    >>> sale.payment_term = payment_term
    >>> sale.invoice_method = 'order'
    >>> sale_line = SaleLine()
    >>> sale.lines.append(sale_line)
    >>> sale_line.product = product
    >>> sale_line.quantity = 3.0
    >>> sale.save()
    >>> Sale.quote([sale.id], config.context)
    >>> Sale.confirm([sale.id], config.context)
    >>> Sale.process([sale.id], config.context)
    >>> sale.state
    u'processing'

Check the invoices::

    >>> config.user = account_user.id
    >>> invoices = Invoice.find([
    ...     ('party', '=', customer_grouped.id),
    ...     ('state', '=', 'draft'),
    ...     ])
    >>> len(invoices)
    2
