    >>> config._context = User.get_preferences(True, config.context)

Configuration production location::

    >>> Location = Model.get('stock.location')
    >>> warehouse, = Location.find([('code', '=', 'WH')])
    >>> production_location, = Location.find([('code', '=', 'PROD')])

    >>> 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.list_price = Decimal(30)
    >>> template.cost_price = Decimal(20)
    >>> template.save()
    >>> product.template = template
    >>> product.save()

Create Components::

    >>> component1 = Product()
    >>> template1 = ProductTemplate()
    >>> template1.name = 'component 1'
    >>> template1.default_uom = unit
    >>> template1.type = 'goods'
    >>> template1.list_price = Decimal(5)
    >>> template1.cost_price = Decimal(1)
    >>> template1.save()
    >>> component1.template = template1
    >>> component1.save()

    >>> meter, = ProductUom.find([('name', '=', 'Meter')])
    >>> centimeter, = ProductUom.find([('name', '=', 'centimeter')])
    >>> component2 = Product()
    >>> template2 = ProductTemplate()
    >>> template2.name = 'component 2'
    >>> template2.default_uom = meter
    >>> template2.type = 'goods'
    >>> template2.list_price = Decimal(7)
    >>> template2.cost_price = Decimal(5)
    >>> template2.save()
    >>> component2.template = template2
    >>> component2.save()

Create Bill of Material::

    >>> BOM = Model.get('production.bom')
    >>> BOMInput = Model.get('production.bom.input')
    >>> BOMOutput = Model.get('production.bom.output')
    >>> bom = BOM(name='product')
    >>> input1 = BOMInput()
    >>> bom.inputs.append(input1)
    >>> input1.product = component1
    >>> input1.quantity = 5
    >>> input2 = BOMInput()
    >>> bom.inputs.append(input2)
    >>> input2.product = component2
    >>> input2.quantity = 150
    >>> input2.uom = centimeter
    >>> output = BOMOutput()
    >>> bom.outputs.append(output)
    >>> output.product = product
    >>> output.quantity = 1
    >>> bom.save()

    >>> ProductBom = Model.get('product.product-production.bom')
    >>> product.boms.append(ProductBom(bom=bom))
    >>> product.save()

Create an Inventory::

    >>> Inventory = Model.get('stock.inventory')
    >>> InventoryLine = Model.get('stock.inventory.line')
    >>> storage, = Location.find([
    ...         ('code', '=', 'STO'),
    ...         ])
    >>> inventory = Inventory()
    >>> inventory.location = storage
    >>> inventory_line1 = InventoryLine()
    >>> inventory.lines.append(inventory_line1)
    >>> inventory_line1.product = component1
    >>> inventory_line1.quantity = 10
    >>> inventory_line2 = InventoryLine()
    >>> inventory.lines.append(inventory_line2)
    >>> inventory_line2.product = component2
    >>> inventory_line2.quantity = 5
    >>> inventory.save()
    >>> Inventory.confirm([inventory.id], config.context)
    >>> inventory.state
    u'done'

Create a production of product::

    >>> Production = Model.get('production')
    >>> production = Production()
    >>> production.product = product
    >>> production.bom = bom
    >>> production.quantity = 2
    >>> sorted([i.quantity for i in production.inputs]) == [10, 300]
    True
    >>> output, = production.outputs
    >>> output.quantity == 2
    True
    >>> production.cost == Decimal('25')
    True
    >>> output.unit_price == Decimal('12.5')
    True
    >>> production.save()

Create a Lot for the produced product::

    >>> output, = production.outputs
    >>> config._context['from_move'] = output.id
    >>> Lot = Model.get('stock.lot')
    >>> lot = Lot(number='1')
    >>> lot.product = product
    >>> lot.cost_price
    >>> lot.save()
    >>> output.lot = lot
    >>> output.save()
    >>> del config._context['from_move']

Make the production::

    >>> Production.wait([production.id], config.context)
    >>> production.state
    u'waiting'
    >>> Production.assign_try([production.id], config.context)
    True
    >>> production.reload()
    >>> all(i.state == 'assigned' for i in production.inputs)
    True
    >>> Production.run([production.id], config.context)
    >>> production.reload()
    >>> all(i.state == 'done' for i in production.inputs)
    True
    >>> Production.done([production.id], config.context)
    >>> production.reload()
    >>> output, = production.outputs
    >>> output.state
    u'done'
    >>> output.lot.cost_price == Decimal('12.5')
    True
