General Setup
=============

Imports::

    >>> import datetime
    >>> from dateutil.relativedelta import relativedelta
    >>> from decimal import Decimal
    >>> from proteus import config, Model, Wizard
    >>> from trytond.tests.tools import activate_modules
    >>> from trytond.modules.company.tests.tools import create_company, \
    ...     get_company
    >>> today = datetime.date.today()

Activate production_output_lot and production_lot_cost::

    >>> config = activate_modules(['production_output_lot', 'production_lot_cost'])

Create company::

    >>> _ = create_company()
    >>> company = get_company()

Reload the context::

    >>> User = Model.get('res.user')
    >>> config._context = User.get_preferences(True, config.context)

Configuration production location::

    >>> Location = Model.get('stock.location')
    >>> warehouse, = Location.find([('code', '=', 'WH')])
    >>> production_location, = Location.find([('code', '=', 'PROD')])
    >>> warehouse.production_location = production_location
    >>> warehouse.save()

Create lot sequence type and produced lots sequence::

    >>> user = User(config.user)
    >>> SequenceType = Model.get('ir.sequence.type')
    >>> sequence_type, = SequenceType.find([('name', '=', 'Stock Lot')])
    >>> Sequence = Model.get('ir.sequence')
    >>> lot_sequence = Sequence(name='Produced Lots',
    ...     sequence_type=sequence_type,
    ...     company=company)
    >>> lot_sequence.save()

Create product with lots required::

    >>> ProductUom = Model.get('product.uom')
    >>> unit, = ProductUom.find([('name', '=', 'Unit')])

    >>> ProductTemplate = Model.get('product.template')
    >>> Product = Model.get('product.product')
    >>> product = Product()
    >>> template = ProductTemplate()
    >>> template.name = 'product'
    >>> template.default_uom = unit
    >>> template.type = 'goods'
    >>> template.producible = True
    >>> template.list_price = Decimal(30)
    >>> template.lot_required = ['supplier', 'customer', 'lost_found',
    ...     'storage', 'production']
    >>> template.save()
    >>> product, = template.products
    >>> product.cost_price = Decimal(20)
    >>> product.save()

Create Components::

    >>> component1 = Product()
    >>> template1 = ProductTemplate()
    >>> template1.name = 'component 1'
    >>> template1.default_uom = unit
    >>> template1.type = 'goods'
    >>> template1.list_price = Decimal(5)
    >>> template1.save()
    >>> component1, = template1.products
    >>> component1.cost_price = Decimal(1)
    >>> component1.save()

    >>> meter, = ProductUom.find([('name', '=', 'Meter')])
    >>> centimeter, = ProductUom.find([('symbol', '=', 'cm')])
    >>> component2 = Product()
    >>> template2 = ProductTemplate()
    >>> template2.name = 'component 2'
    >>> template2.default_uom = meter
    >>> template2.type = 'goods'
    >>> template2.list_price = Decimal(7)
    >>> template2.save()
    >>> component2, = template2.products
    >>> component2.cost_price = Decimal(5)
    >>> component2.save()

Create Bill of Material with infrastructure cost::

    >>> BOM = Model.get('production.bom')
    >>> BOMInput = Model.get('production.bom.input')
    >>> BOMOutput = Model.get('production.bom.output')
    >>> bom = BOM(name='product')
    >>> input1 = BOMInput()
    >>> bom.inputs.append(input1)
    >>> input1.product = component1
    >>> input1.quantity = 5
    >>> input2 = BOMInput()
    >>> bom.inputs.append(input2)
    >>> input2.product = component2
    >>> input2.quantity = 150
    >>> input2.unit = centimeter
    >>> output = BOMOutput()
    >>> bom.outputs.append(output)
    >>> output.product = product
    >>> output.quantity = 1
    >>> bom.infrastructure_cost = Decimal('1.0')
    >>> bom.save()

    >>> ProductBom = Model.get('product.product-production.bom')
    >>> product.boms.append(ProductBom(bom=bom))
    >>> product.save()

Create an Inventory::

    >>> Inventory = Model.get('stock.inventory')
    >>> InventoryLine = Model.get('stock.inventory.line')
    >>> storage, = Location.find([
    ...         ('code', '=', 'STO'),
    ...         ])
    >>> inventory = Inventory()
    >>> inventory.location = storage
    >>> inventory_line1 = InventoryLine()
    >>> inventory.lines.append(inventory_line1)
    >>> inventory_line1.product = component1
    >>> inventory_line1.quantity = 20
    >>> inventory_line2 = InventoryLine()
    >>> inventory.lines.append(inventory_line2)
    >>> inventory_line2.product = component2
    >>> inventory_line2.quantity = 10
    >>> inventory.save()
    >>> inventory.click('confirm')
    >>> inventory.state
    'done'

Configure production to automatically create lots on running state::

    >>> ProductionConfig = Model.get('production.configuration')
    >>> production_config = ProductionConfig(1)
    >>> production_config.output_lot_creation = 'running'
    >>> production_config.output_lot_sequence = lot_sequence
    >>> production_config.save()

Make a production with infrastructure cost and lots automatically created when
production is Running::

    >>> Production = Model.get('production')
    >>> production = Production()
    >>> production.product = product
    >>> production.bom = bom
    >>> production.quantity = 2
    >>> sorted([i.quantity for i in production.inputs]) == [10, 300]
    True
    >>> output, = production.outputs
    >>> output.quantity == 2
    True
    >>> production.save()
    >>> production.click('wait')
    >>> production.state
    'waiting'
    >>> production.click('assign_try')
    >>> all(i.state == 'assigned' for i in production.inputs)
    True
    >>> production.click('run')
    >>> all(i.state == 'done' for i in production.inputs)
    True
    >>> output, = production.outputs
    >>> output.lot != None
    True
    >>> production.click('done')
    >>> output, = production.outputs
    >>> output.state
    'done'
    >>> production.cost == Decimal('27')
    True
    >>> output.unit_price
    Decimal('13.5000')
    >>> output.lot.cost_price == Decimal('13.5')
    True

Configure production to automatically create lots on done state::

    >>> production_config.output_lot_creation = 'done'
    >>> production_config.save()

Make a production with infrastructure cost and lots automatically created when
production is done::

    >>> production = Production()
    >>> production.product = product
    >>> production.bom = bom
    >>> production.quantity = 2
    >>> sorted([i.quantity for i in production.inputs]) == [10, 300]
    True
    >>> output, = production.outputs
    >>> output.quantity == 2
    True
    >>> production.save()
    >>> production.click('wait')
    >>> production.state
    'waiting'
    >>> production.click('assign_try')
    >>> all(i.state == 'assigned' for i in production.inputs)
    True
    >>> production.click('run')
    >>> all(i.state == 'done' for i in production.inputs)
    True
    >>> output, = production.outputs
    >>> output.lot
    >>> production.click('done')
    >>> output, = production.outputs
    >>> output.state
    'done'
    >>> output.lot != None
    True
    >>> production.cost == Decimal('27')
    True
    >>> output.unit_price
    Decimal('13.5000')
    >>> output.lot.cost_price == Decimal('13.5')
    True
