+Imports::
+
+    >>> import datetime
+    >>> from decimal import Decimal
+    >>> from proteus import Model
+    >>> from trytond.tests.tools import activate_modules
+    >>> from trytond.modules.company.tests.tools import create_company, \
+    ...     get_company
+    >>> today = datetime.date.today()
+
+Install product_cost_fifo Module::
+
+    >>> config = activate_modules('product_cost_fifo')
+
+Create company::
+
+    >>> _ = create_company()
+    >>> company = get_company()
+
+Create product::
+
+    >>> ProductUom = Model.get('product.uom')
+    >>> ProductTemplate = Model.get('product.template')
+    >>> unit, = ProductUom.find([('name', '=', 'Unit')])

+    >>> product, = template.products
+    >>> product.cost_price = Decimal('80')
+    >>> template.save()
+    >>> product, = template.products
+
+Get stock locations::
+
+    >>> Location = Model.get('stock.location')
+    >>> supplier_loc, = Location.find([('code', '=', 'SUP')])
+    >>> customer_loc, = Location.find([('code', '=', 'CUS')])
+    >>> storage_loc, = Location.find([('code', '=', 'STO')])
+
+Make 2 units of the product not available @ 60 and 80 ::
+
+    >>> StockMove = Model.get('stock.move')
+    >>> incoming_move = StockMove()
+    >>> incoming_move.product = product
+    >>> incoming_move.uom = unit
+    >>> incoming_move.quantity = 1

+    >>> incoming_move.company = company
+    >>> incoming_move.unit_price = Decimal('60')
+    >>> incoming_move.currency = company.currency
+    >>> incoming_move.fifo_quantity = 1
+    >>> incoming_move.click('do')
+
+    >>> incoming_move = StockMove()

+    >>> incoming_move.currency = company.currency
+    >>> incoming_move.fifo_quantity = 1
+    >>> incoming_move.click('do')
+
+Sell 1 unit @ 200::
+
+    >>> StockMove = Model.get('stock.move')
+    >>> outgoing_move = StockMove()
+    >>> outgoing_move.product = product
+    >>> outgoing_move.uom = unit

+    >>> outgoing_move.unit_price = Decimal('200')
+    >>> outgoing_move.currency = company.currency
+    >>> outgoing_move.click('do')
+
+Check Cost Price FIFO is the current cost price::
+
+    >>> product.reload()
+    >>> product.cost_price
+    Decimal('70.0000')
+    >>> outgoing_move.cost_price
+    Decimal('70.0000')
