+Product Replace Scenario
+========================
+
+Imports::
+
+    >>> from proteus import Model, Wizard
+    >>> from trytond.tests.tools import activate_modules, assertEqual, assertFalse
+
+Activate modules::
+
+    >>> config = activate_modules('product')
+
+    >>> Cron = Model.get('ir.cron')
+    >>> ProductTemplate = Model.get('product.template')
+    >>> UoM = Model.get('product.uom')
+
+Get units::
+
+    >>> unit, = UoM.find([('name', '=', "Unit")])
+    >>> kg, = UoM.find([('name', '=', "Kilogram")])
+
+Create a product::
+
+    >>> template = ProductTemplate()
+    >>> template.name = "Product"
+    >>> template.type = 'goods'
+    >>> template.default_uom = kg
+    >>> template.save()
+    >>> product1, = template.products
+
+Create a second product::
+
+    >>> template = ProductTemplate()
+    >>> template.name = "Product"
+    >>> template.type = 'service'
+    >>> template.default_uom = unit
+    >>> template.save()
+    >>> product2, = template.products
+
+Try to replace goods with service::
+
+    >>> replace = Wizard('product.product.replace', models=[product1])
+    >>> assertEqual(replace.form.source, product1)
+    >>> replace.form.destination = product2
+    >>> replace.execute('replace')
+    Traceback (most recent call last):
+        ...
+    DomainValidationError: ...
+
+Try to replace with different categories of unit of measure::
+
+    >>> product2.template.type = 'goods'
+    >>> product2.template.save()
+
+    >>> replace = Wizard('product.product.replace', models=[product1])
+    >>> replace.form.destination = product2
+    >>> replace.execute('replace')
+    Traceback (most recent call last):
+        ...
+    DomainValidationError: ...
+
+Replace product::
+
+    >>> product2.template.default_uom = kg
+    >>> product2.template.save()
+
+    >>> replace = Wizard('product.product.replace', models=[product1])
+    >>> replace.form.destination = product2
+    >>> replace.execute('replace')
+    >>> assertEqual(product1.replaced_by, product2)
+    >>> assertFalse(product1.active)
+
+Cron task deactivate replaced product::
+
+    >>> product1.active = True
+    >>> product1.save()
+
+    >>> deactivate_replaced, = Cron.find([
+    ...     ('method', '=', 'product.product|deactivate_replaced'),
+    ...     ])
+    >>> deactivate_replaced.click('run_once')
+
+    >>> product1.reload()
+    >>> assertFalse(product1.active)
