+Production Lot Trace Scenario
+=============================
+
+Imports::
+
+    >>> from decimal import Decimal
+
+    >>> from proteus import Model
+    >>> from trytond.modules.company.tests.tools import create_company
+    >>> from trytond.tests.tools import activate_modules
+
+Activate modules::
+
+    >>> config = activate_modules(['stock_lot', 'production'], create_company)
+
+    >>> Lot = Model.get('stock.lot')
+    >>> LotTrace = Model.get('stock.lot.trace')
+    >>> ProductTemplate = Model.get('product.template')
+    >>> Production = Model.get('production')
+    >>> UoM = Model.get('product.uom')
+
+Create product::
+
+    >>> unit, = UoM.find([('name', '=', 'Unit')])
+
+    >>> template = ProductTemplate(name="Product")
+    >>> template.type = 'goods'
+    >>> template.default_uom = unit
+    >>> template.producible = True
+    >>> template.list_price = Decimal(1)
+    >>> template.save()
+    >>> product, = template.products
+
+Create component::
+
+    >>> template = ProductTemplate(name="Component")
+    >>> template.type = 'goods'
+    >>> template.default_uom = unit
+    >>> template.save()
+    >>> component, = template.products
+
+Create Lots::
+
+    >>> product_lot = Lot(product=product, number="1")
+    >>> product_lot.save()
+    >>> component_lot = Lot(product=component, number="2")
+    >>> component_lot.save()
+
+Make a production::
+
+    >>> production = Production()
+    >>> input = production.inputs.new()
+    >>> input.from_location = production.warehouse.storage_location
+    >>> input.to_location = production.location
+    >>> input.product = component
+    >>> input.lot = component_lot
+    >>> input.quantity = 1
+    >>> output = production.outputs.new()
+    >>> output.from_location = production.location
+    >>> output.to_location = production.warehouse.storage_location
+    >>> output.product = product
+    >>> output.lot = product_lot
+    >>> output.quantity = 1
+    >>> output.currency = production.company.currency
+    >>> output.unit_price = Decimal(0)
+    >>> production.click('wait')
+    >>> production.click('assign_force')
+    >>> production.click('run')
+    >>> production.click('do')
+    >>> production.state
+    'done'
+
+
+Check lot traces::
+
+    >>> trace, = LotTrace.find([('lot', '=', product_lot.id)])
+    >>> trace.document == production
+    True
+    >>> trace.upward_traces
+    []
+    >>> trace, = trace.downward_traces
+    >>> trace.document == production
+    True
+    >>> trace.product == component
+    True
+
+    >>> trace, = LotTrace.find([('lot', '=', component_lot.id)])
+    >>> trace.document == production
+    True
+    >>> trace.downward_traces
+    []
+    >>> trace, = trace.upward_traces
+    >>> trace.document == production
+    True
+    >>> trace.product == product
+    True
