+Stock Lot Unit Scenario
+=======================
+
+Imports::
+
+    >>> from decimal import Decimal
+
+    >>> from proteus import Model
+    >>> from trytond.modules.company.tests.tools import create_company
+    >>> from trytond.modules.currency.tests.tools import get_currency
+    >>> from trytond.tests.tools import activate_modules, assertEqual
+
+Activate modules::
+
+    >>> config = activate_modules('stock_lot_unit', create_company)
+
+Get currency::
+
+    >>> currency = get_currency()
+
+Create customer::
+
+    >>> Party = Model.get('party.party')
+    >>> customer = Party(name='Customer')
+    >>> customer.save()
+
+Create supplier::
+
+    >>> supplier = Party(name='Supplier')
+    >>> supplier.save()
+
+Create product::
+
+    >>> ProductUom = Model.get('product.uom')
+    >>> ProductTemplate = Model.get('product.template')
+    >>> unit, = ProductUom.find([('name', '=', 'Unit')])
+    >>> template = ProductTemplate()
+    >>> template.name = 'Product'
+    >>> template.default_uom = unit
+    >>> template.type = 'goods'
+    >>> template.list_price = Decimal('20')
+    >>> template.lot_uom = unit
+    >>> template.save()
+    >>> product, = template.products
+    >>> product.cost_price = Decimal('8')
+    >>> product.save()
+
+Get stock locations::
+
+    >>> Location = Model.get('stock.location')
+    >>> warehouse_loc, = Location.find([('code', '=', 'WH')])
+    >>> supplier_loc, = Location.find([('code', '=', 'SUP')])
+    >>> customer_loc, = Location.find([('code', '=', 'CUS')])
+    >>> input_loc, = Location.find([('code', '=', 'IN')])
+    >>> output_loc, = Location.find([('code', '=', 'OUT')])
+    >>> storage_loc, = Location.find([('code', '=', 'STO')])
+
+Create an incoming shipment without lot::
+
+    >>> ShipmentIn = Model.get('stock.shipment.in')
+    >>> shipment = ShipmentIn()
+    >>> shipment.supplier = supplier
+    >>> move1 = shipment.incoming_moves.new()
+    >>> move1.product = product
+    >>> move1.quantity = 60
+    >>> move1.unit_price = Decimal('8')
+    >>> move1.currency = currency
+    >>> move1.from_location = supplier_loc
+    >>> move1.to_location = input_loc
+    >>> move2 = shipment.incoming_moves.new()
+    >>> move2.product = product
+    >>> move2.quantity = 40
+    >>> move2.unit_price = Decimal('8')
+    >>> move2.currency = currency
+    >>> move2.from_location = supplier_loc
+    >>> move2.to_location = input_loc
+    >>> shipment.click('receive')
+    >>> shipment.click('do')
+
+Let's ship a product with a lot::
+
+    >>> Lot = Model.get('stock.lot')
+    >>> lot = Lot(number='00001', product=product)
+    >>> assertEqual(lot.unit, unit)
+    >>> lot.unit_quantity
+    1.0
+    >>> lot.save()
+
+    >>> ShipmentOut = Model.get('stock.shipment.out')
+    >>> shipment = ShipmentOut()
+    >>> shipment.customer = customer
+    >>> move = shipment.outgoing_moves.new()
+    >>> move.product = product
+    >>> move.quantity = 1
+    >>> move.unit_price = Decimal('20')
+    >>> move.currency = currency
+    >>> move.from_location = output_loc
+    >>> move.to_location = customer_loc
+    >>> shipment.click('wait')
+    >>> shipment.click('assign_try')
+    >>> move.lot = lot
+    >>> shipment.click('pick')
+    >>> shipment.click('pack')
+    >>> shipment.click('do')
+
+Let's ship now two times the same lot::
+
+    >>> lot = Lot(number='00002', product=product)
+    >>> lot.save()
+
+    >>> shipment = ShipmentOut()
+    >>> shipment.customer = customer
+    >>> move1 = shipment.outgoing_moves.new()
+    >>> move1.product = product
+    >>> move1.quantity = 1
+    >>> move1.unit_price = Decimal('20')
+    >>> move1.currency = currency
+    >>> move1.from_location = output_loc
+    >>> move1.to_location = customer_loc
+    >>> move2 = shipment.outgoing_moves.new()
+    >>> move2.product = product
+    >>> move2.quantity = 1
+    >>> move2.unit_price = Decimal('20')
+    >>> move2.currency = currency
+    >>> move2.from_location = output_loc
+    >>> move2.to_location = customer_loc
+    >>> shipment.click('wait')
+    >>> shipment.click('assign_try')
+    >>> move1, move2 = shipment.inventory_moves
+    >>> move1.lot = lot
+    >>> move2.lot = lot
+    >>> shipment.save()
+    >>> shipment.click('pick')
+    Traceback (most recent call last):
+        ...
+    LotUnitQuantityError: ...
+
+Now let's ship one move with a quantity bigger than lot unit quantity::
+
+    >>> lot = Lot(number='00003', product=product)
+    >>> lot.unit_quantity = 3
+    >>> lot.save()
+
+    >>> shipment = ShipmentOut()
+    >>> shipment.customer = customer
+    >>> move = shipment.outgoing_moves.new()
+    >>> move.product = product
+    >>> move.quantity = 4
+    >>> move.unit_price = Decimal('20')
+    >>> move.currency = currency
+    >>> move.from_location = output_loc
+    >>> move.to_location = customer_loc
+    >>> shipment.click('wait')
+    >>> shipment.click('assign_try')
+    >>> move, = shipment.inventory_moves
+    >>> move.lot = lot
+    >>> shipment.click('pick')
+    Traceback (most recent call last):
+        ...
+    LotUnitQuantityError: ...
+
+Make an inventory::
+
+    >>> lot = Lot(number='00004', product=product)
+    >>> lot.unit_quantity = 2
+    >>> lot.save()
+
+    >>> Inventory = Model.get('stock.inventory')
+    >>> inventory = Inventory()
+    >>> inventory.location = storage_loc
+    >>> line = inventory.lines.new()
+    >>> line.product = product
+    >>> line.lot = lot
+    >>> line.quantity = 3
+    >>> inventory.save()
+    >>> inventory.click('confirm')
+    Traceback (most recent call last):
+        ...
+    LotUnitQuantityError: ...
+
+    >>> line, = inventory.lines
+    >>> line.quantity = 2
+    >>> inventory.click('confirm')
