++    name: 00001
++    product_id: product_product_hppaviliondesktoppcs0

++  I update stock of 'HP Pavilion Desktop PCs' with 10 PCE in Stock with Production Lot.
++-
++  !record {model: stock.change.product.qty, id: update_qty_with_lot}:
++    location_id: stock_location_stock
++    new_quantity: 10
++    product_id: product_product_hppaviliondesktoppcs0
++    prodlot_id: lot_hp_pc_1
++-
++  Now I run the update wizard and update stock.
++-
++  !python {model: stock.change.product.qty}: |
++    self.change_product_qty(cr, uid, [ref('update_qty_with_lot')], context=context)
++-
++  I check real stock of 'HP Pavilion Desktop PCs'.
++-
++  !python {model: product.product}: |
++    product = self.browse(cr, uid, ref('product_product_hppaviliondesktoppcs0'), context=context)
++    assert product.qty_available == 20, "Real stock is not 20 PCE."
++-
++  The current stock of the 'HP Pavilion Desktop PCs' is 20 PCE.

++    location_id: stock_location_stock
++    new_quantity: 10
++    product_id: product_product_hppaviliondesktoppcs0
++-
++  I try to update more 10 PCE in Stock without Production Lot.
++-
++  !python {model: stock.change.product.qty}: |
++    self.change_product_qty(cr, uid, [ref('update_qty_nolot')], context=context)
++-
++  I again check real stock of 'HP Pavilion Desktop PCs'.
++-
++  !python {model: product.product}: |
++    product = self.browse(cr, uid, ref('product_product_hppaviliondesktoppcs0'), context=context)
++    assert product.qty_available == 20, "Real stock is updated with 10 more PCE."
++-
++  I confirm available stock of 'HP Pavilion Desktop PCs' is still 20 PCE.
