+
+Activate modules::
+
+    >>> config = activate_modules('stock', create_company)
+
+Get currency::

+
+Get stock locations::
+
+    >>> Location = Model.get('stock.location')
+    >>> supplier_loc, = Location.find([('code', '=', 'SUP')])

+
+Fill storage::
+
+    >>> StockMove = Model.get('stock.move')
+    >>> incoming_move = StockMove()
+    >>> incoming_move.product = product
+    >>> incoming_move.unit = unit
+    >>> incoming_move.quantity = 1
+    >>> incoming_move.from_location = supplier_loc

+    >>> incoming_move.currency = currency
+    >>> incoming_moves.append(incoming_move)
+    >>> StockMove.click(incoming_moves, 'do')
+
+Create an inventory::
+
+    >>> Inventory = Model.get('stock.inventory')
+    >>> inventory = Inventory()
+    >>> inventory.location = storage_loc
+    >>> inventory.empty_quantity = 'keep'
+    >>> inventory.save()
+    >>> inventory.click('complete_lines')
+    >>> line_by_product = {l.product.id: l for l in inventory.lines}

+    >>> line_p2 = line_by_product[product2.id]
+    >>> line_p2.expected_quantity
+    2.5
+    >>> inventory.save()
+
+Fill storage with more quantities::
+
+    >>> incoming_move = StockMove()
+    >>> incoming_move.product = product
+    >>> incoming_move.unit = unit
+    >>> incoming_move.quantity = 1
+    >>> incoming_move.from_location = supplier_loc
+    >>> incoming_move.to_location = storage_loc
+    >>> incoming_move.planned_date = today
+    >>> incoming_move.effective_date = today
+    >>> incoming_move.unit_price = Decimal('100')
+    >>> incoming_move.currency = currency
+    >>> incoming_moves = [incoming_move]
+
+    >>> incoming_move = StockMove()
+    >>> incoming_move.product = product2
+    >>> incoming_move.unit = kg
+    >>> incoming_move.quantity = 1.3
+    >>> incoming_move.from_location = supplier_loc
+    >>> incoming_move.to_location = storage_loc
+    >>> incoming_move.planned_date = today
+    >>> incoming_move.effective_date = today
+    >>> incoming_move.unit_price = Decimal('70')
+    >>> incoming_move.currency = currency
+    >>> incoming_moves.append(incoming_move)
+    >>> StockMove.click(incoming_moves, 'do')
+
+Update the inventory::
+
+    >>> inventory.click('complete_lines')
+    >>> line_p1.reload()
+    >>> line_p1.expected_quantity
+    2.0
+    >>> line_p1.quantity
+    3.0
+    >>> line_p2.reload()
+    >>> line_p2.expected_quantity
+    3.8
+    >>> line_p2.quantity = 3.8
+    >>> line_p2.save()
+
+Confirm the inventory::
+
+    >>> inventory.click('confirm')
+    >>> line_p1.reload()
+    >>> line_p1.expected_quantity
+    2.0
+    >>> move, = line_p1.moves
+    >>> move.quantity
+    1.0
+    >>> assertEqual(move.from_location, lost_found_loc)
+    >>> assertEqual(move.to_location, inventory.location)
+    >>> line_p2.reload()
+    >>> len(line_p2.moves)
+    0
+
+Creating an inventory with empty quantities::
+
+    >>> inventory = Inventory()
+    >>> inventory.location = storage_loc
+    >>> inventory.empty_quantity = 'keep'
+    >>> line = inventory.lines.new()
+    >>> line.product = product
+    >>> inventory.click('confirm')
+    >>> line, = inventory.lines
+    >>> len(line.moves)
+    0
+
+Empty storage::
+
+    >>> Inventory = Model.get('stock.inventory')
+    >>> inventory = Inventory()
+    >>> inventory.location = storage_loc
+    >>> inventory.empty_quantity = 'keep'
+    >>> line = inventory.lines.new()
+    >>> line.product = product
+    >>> line.quantity = 0
+    >>> line = inventory.lines.new()
+    >>> line.product = product2
+    >>> line.quantity = 0
+    >>> inventory.save()
+    >>> line_p1, line_p2 = inventory.lines
+    >>> line_p1.quantity
+    0.0
+    >>> line_p1.expected_quantity
+    3.0
+    >>> line_p2.quantity
+    0.0
+    >>> line_p2.expected_quantity
+    3.8
+    >>> inventory.click('confirm')
+
+Add quantity of consumable product::
+
+    >>> inventory = Inventory()
+    >>> inventory.location = storage_loc
+    >>> inventory.empty_quantity = 'keep'
+    >>> line = inventory.lines.new()
+    >>> line.product = consumable
+    >>> line.quantity = 5.0
+    >>> inventory.click('complete_lines')
+    >>> len(inventory.lines)
+    1
+    >>> inventory.click('confirm')
+    >>> line, = inventory.lines
+    >>> move, = line.moves
+    >>> move.quantity
+    5.0
+    >>> assertEqual(move.from_location, lost_found_loc)
+    >>> assertEqual(move.to_location, inventory.location)
+
+Create an inventory that should be empty after completion::
+
+    >>> Inventory = Model.get('stock.inventory')
+    >>> inventory = Inventory()
+    >>> inventory.location = storage_loc
+    >>> inventory.empty_quantity = 'keep'
+    >>> inventory.click('complete_lines')
+    >>> len(inventory.lines)
+    0
+
+Create an inventory and check rec_name::
+
+    >>> Inventory = Model.get('stock.inventory')
+    >>> inventory = Inventory()
+    >>> inventory.date = dt.date(2023, 1, 31)
+    >>> inventory.location = storage_loc
+    >>> inventory.empty_quantity = 'keep'
+    >>> inventory.save()
+    >>> inventory.rec_name
+    '[6] [STO] Storage Zone @ 01/31/2023'
