+Imports::

+    >>> from proteus import Model
+    >>> from trytond.modules.account.tests.tools import (

+
+Activate modules::
+
+    >>> config = activate_modules('sale_point', create_company, create_chart)
+
+    >>> Journal = Model.get('account.journal')
+    >>> Location = Model.get('stock.location')
+    >>> POS = Model.get('sale.point')
+    >>> PaymentMethod = Model.get('sale.point.payment.method')
+    >>> ProductCategory = Model.get('product.category')

+    >>> SequenceType = Model.get('ir.sequence.type')
+    >>> Session = Model.get('sale.point.cash.session')
+    >>> TransferType = Model.get('sale.point.cash.transfer.type')
+
+Create fiscal year::
+
+    >>> fiscalyear = set_fiscalyear_invoice_sequences(create_fiscalyear())
+    >>> fiscalyear.click('create_period')
+
+Get accounts::
+
+    >>> accounts = get_accounts()
+
+Create account categories::
+
+    >>> account_category = ProductCategory(name="Account Category")
+    >>> account_category.accounting = True
+    >>> account_category.account_revenue = accounts['revenue']
+    >>> account_category.save()
+
+Create product::
+
+    >>> unit, = ProductUom.find([('name', '=', 'Unit')])
+
+    >>> template = ProductTemplate()
+    >>> template.name = 'product'
+    >>> template.default_uom = unit
+    >>> template.salable = True
+    >>> template.account_category = account_category
+    >>> template.gross_price = Decimal('20.0000')
+    >>> template.save()
+    >>> product, = template.products
+
+Get journal::
+
+    >>> journal_revenue, = Journal.find([('type', '=', 'revenue')], limit=1)
+
+Get stock locations::
+
+    >>> storage_loc, = Location.find([('code', '=', 'STO')])
+    >>> customer_loc, = Location.find([('code', '=', 'CUS')])
+
+Create POS::
+
+    >>> pos = POS(name="POS")
+    >>> pos.journal = journal_revenue
+    >>> pos.sequence = SequenceStrict(name="POS", company=pos.company)
+    >>> pos.sequence.sequence_type, = SequenceType.find(
+    ...     [('name', '=', "POS")], limit=1)
+    >>> pos.sequence.save()
+    >>> pos.storage_location = storage_loc
+    >>> pos.customer_location = customer_loc
+    >>> pos.save()
+
+Create cash payment method::
+
+    >>> cash_method = PaymentMethod(name="Cash")
+    >>> cash_method.account = accounts['cash']
+    >>> cash_method.cash = True
+    >>> cash_method.save()
+
+Create transfer type::
+
+    >>> transfer_type = TransferType(name="Bank")
+    >>> transfer_type.journal, = Journal.find([('type', '=', 'cash')], limit=1)
+    >>> accounts['bank'], = accounts['cash'].duplicate(default={'name': "Bank"})
+    >>> transfer_type.account = accounts['bank']
+    >>> transfer_type.save()
+
+Create an initial cash session::
+
+    >>> session = Session(point=pos)
+    >>> transfer = session.transfers.new(point=pos)
+    >>> transfer.type = transfer_type
+    >>> transfer.amount = Decimal('100.00')
+    >>> session.end_amount = Decimal('100.00')
+    >>> session.save()
+    >>> session.start_amount
+    Decimal('0')
+    >>> session.balance
+    Decimal('100.00')
+    >>> session.end_amount
+    Decimal('100.00')
+
+    >>> session.click('close')
+    >>> session.state
+    'closed'
+    >>> session.click('post')
+    >>> session.state
+    'posted'
+
+    >>> transfer, = session.transfers
+    >>> transfer.state
+    'posted'
+    >>> transfer.move.state
+    'posted'
+    >>> accounts['bank'].reload()
+    >>> accounts['bank'].balance
+    Decimal('-100.00')
+
+Make a sale::
+
+    >>> sale = Sale(point=pos)
+    >>> line = sale.lines.new()
+    >>> line.product = product
+    >>> line.quantity = 1
+    >>> sale.save()
+    >>> sale.total
+    Decimal('20.00')
+
+Pay by cash::
+
+    >>> payment = sale.click('pay')
+    >>> payment.form.method = cash_method
+    >>> payment.form.amount
+    Decimal('20.00')
+    >>> payment.execute('pay')
+
+    >>> sale.state
+    'done'
+    >>> payment, = sale.payments
+
+Check the new session::
+
+    >>> session = payment.session
+    >>> session.state
+    'open'
+    >>> session.start_amount
+    Decimal('100.00')
+    >>> session.balance
+    Decimal('20.00')
+
+Try to close::
+
+    >>> session.click('close')
+    Traceback (most recent call last):
+        ...
+    SessionValidationError: ...
+
+    >>> session.end_amount = Decimal('120.00')
+    >>> session.click('close')
+    >>> session.state
+    'closed'
