+Stock Lot Number Scenario
+=========================
+
+Imports::
+
+    >>> from proteus import Model
+    >>> from trytond.tests.tools import activate_modules, assertEqual
+
+Activate modules::
+
+    >>> config = activate_modules('stock_lot')
+
+Create lot sequence::
+
+    >>> Sequence = Model.get('ir.sequence')
+    >>> SequenceType = Model.get('ir.sequence.type')
+    >>> sequence_type, = SequenceType.find(
+    ...     [('name', '=', "Stock Lot")], limit=1)
+    >>> sequence = Sequence(name="Lot", sequence_type=sequence_type)
+    >>> sequence.save()
+
+Set default sequence::
+
+    >>> Configuration = Model.get('product.configuration')
+    >>> configuration = Configuration(1)
+    >>> configuration.default_lot_sequence = sequence
+    >>> configuration.save()
+
+Create product::
+
+    >>> ProductUom = Model.get('product.uom')
+    >>> ProductTemplate = Model.get('product.template')
+    >>> unit, = ProductUom.find([('name', '=', 'Unit')])
+
+    >>> template = ProductTemplate()
+    >>> assertEqual(template.lot_sequence, sequence)
+    >>> template.name = 'Product'
+    >>> template.default_uom = unit
+    >>> template.type = 'goods'
+    >>> template.save()
+    >>> product, = template.products
+
+Create lot without number::
+
+    >>> Lot = Model.get('stock.lot')
+    >>> lot = Lot(product=product)
+    >>> lot.save()
+
+    >>> lot.number
+    '1'
+
+Copy set a new number::
+
+    >>> lot2, = lot.duplicate()
+    >>> lot2.number
+    '2'
+
+Copy without sequence keep same number::
+
+    >>> template.lot_sequence = None
+    >>> template.save()
+    >>> lot3, = lot.duplicate()
+    >>> lot3.number
+    '1'
