+Product Identifier Scenario
+===========================
+
+Imports::
+
+    >>> from proteus import Model
+    >>> from trytond.tests.tools import activate_modules
+
+Activate modules::
+
+    >>> config = activate_modules('product')
+
+Create product::
+
+    >>> ProductUom = Model.get('product.uom')
+    >>> unit, = ProductUom.find([('name', '=', 'Unit')])
+    >>> ProductTemplate = Model.get('product.template')
+    >>> template = ProductTemplate()
+    >>> template.name = 'product'
+    >>> template.default_uom = unit
+    >>> template.type = 'service'
+    >>> template.save()
+    >>> product, = template.products
+
+The identifier code is computed when set::
+
+    >>> identifier = product.identifiers.new()
+    >>> identifier.type = 'ean'
+    >>> identifier.code = '123 456 7890 123'
+    >>> identifier.code
+    '1234567890123'
+
+An Error is raised for invalid code::
+
+    >>> product.save()
+    Traceback (most recent call last):
+        ...
+    InvalidIdentifierCode: ...
+
+Valid codes are saved correctly::
+
+    >>> identifier.code = '978-0-471-11709-4'
+    >>> product.save()
+    >>> identifier, = product.identifiers
+    >>> identifier.code
+    '9780471117094'
