+
+Activate modules::

+    >>> config = activate_modules('product_cost_history', create_company)
+
+    >>> Date = Model.get('ir.date')
+
+Setup company::
+
+    >>> company = get_company()

+    >>> company.save()
+
+    >>> today = Date.today(config.context)

+
+Cost history is empty::
+
+    >>> ProductCostHistory = Model.get('product.product.cost_history')
+    >>> ProductCostHistory.find([])
+    []
+
+Create some moves at different dates and with different cost::

+
+
+Check cost history::
+
+    >>> order = [('date', 'ASC')]
+    >>> [c.cost_price for c in ProductCostHistory.find([], order=order)]
+    [Decimal('100.0000'), Decimal('120.0000'), Decimal('110.0000')]

+    ...     today - dt.timedelta(days=2),
+    ...     today - dt.timedelta(days=1),
+    ...     today])
+
+Check cost price history on product::
+
+    >>> product.reload()
+    >>> product.cost_price
+    Decimal('110.0000')
+
+    >>> with config.set_context(_datetime=now - dt.timedelta(days=3)):

+    ...     product = Product(product.id)
+    >>> product.cost_price
+    Decimal('120.0000')
+
+
+Create service::
+
+    >>> template = ProductTemplate()
+    >>> template.name = 'Service'
+    >>> template.default_uom = unit
+    >>> template.type = 'service'
+    >>> template.list_price = Decimal('50.0000')

+    >>> service.cost_price = Decimal('30.0000')
+    >>> template.save()
+    >>> sevice, = template.products
+
+Update cost price::
+
+    >>> service.cost_price += 5
+    >>> service.save()
+
+Check cost history::
+
+    >>> history, = ProductCostHistory.find([('product', '=', service.id)])
+    >>> history.cost_price
+    Decimal('35.0000')
