Account Asset Scenario
======================

Imports::

    >>> from decimal import Decimal

    >>> from dateutil.relativedelta import relativedelta

    >>> from proteus import Model, Wizard
    >>> from trytond.modules.account.tests.tools import (
    ...     create_chart, create_fiscalyear, get_accounts)
    >>> from trytond.modules.account_asset.tests.tools import add_asset_accounts

    >>> from trytond.modules.company.tests.tools import create_company
    >>> from trytond.tests.tools import activate_modules, assertEqual

Activate modules::

    >>> config = activate_modules('account_asset', create_company, create_chart)

Create fiscal year::

    >>> fiscalyear = set_fiscalyear_invoice_sequences(
    ...     create_fiscalyear())
    >>> fiscalyear.click('create_period')

Get accounts::

    >>> accounts = add_asset_accounts(get_accounts())
    >>> revenue = accounts['revenue']
    >>> asset_account = accounts['asset']
    >>> expense = accounts['expense']
    >>> depreciation_account = accounts['depreciation']

Create account category::

    >>> ProductCategory = Model.get('product.category')
    >>> account_category = ProductCategory(name="Account Category")
    >>> account_category.accounting = True
    >>> account_category.account_expense = expense
    >>> account_category.account_revenue = revenue
    >>> account_category.account_asset = asset_account
    >>> account_category.account_depreciation = depreciation_account
    >>> account_category.save()

Create an asset::

    >>> ProductUom = Model.get('product.uom')
    >>> unit, = ProductUom.find([('name', '=', 'Unit')])
    >>> ProductTemplate = Model.get('product.template')
    >>> Product = Model.get('product.product')
    >>> asset_product = Product()
    >>> asset_template = ProductTemplate()
    >>> asset_template.name = 'Asset'
    >>> asset_template.type = 'assets'
    >>> asset_template.default_uom = unit
    >>> asset_template.list_price = Decimal('1000')
    >>> asset_template.account_category = account_category
    >>> asset_template.depreciable = True
    >>> asset_template.depreciation_duration = 24
    >>> asset_template.save()
    >>> asset_product, = asset_template.products

Create supplier::

    >>> Party = Model.get('party.party')
    >>> supplier = Party(name='Supplier')
    >>> supplier.save()
    >>> customer = Party(name='Customer')
    >>> customer.save()

Create payment term::

    >>> payment_term = create_payment_term()
    >>> payment_term.save()

Buy an asset::

    >>> Invoice = Model.get('account.invoice')
    >>> InvoiceLine = Model.get('account.invoice.line')
    >>> supplier_invoice = Invoice(type='in')
    >>> supplier_invoice.party = supplier
    >>> invoice_line = InvoiceLine()
    >>> supplier_invoice.lines.append(invoice_line)
    >>> invoice_line.product = asset_product
    >>> invoice_line.quantity = 1
    >>> invoice_line.unit_price = Decimal('1000')
    >>> assertEqual(invoice_line.account, asset_account)
    >>> supplier_invoice.invoice_date = fiscalyear.start_date
    >>> supplier_invoice.click('post')
    >>> supplier_invoice.state
    'posted'
    >>> invoice_line, = supplier_invoice.lines
    >>> (asset_account.debit, asset_account.credit)
    (Decimal('1000.00'), Decimal('0.00'))

Depreciate the asset::

    >>> Asset = Model.get('account.asset')
    >>> asset = Asset()
    >>> asset.product = asset_product
    >>> asset.supplier_invoice_line = invoice_line
    >>> asset.value
    Decimal('1000.00')
    >>> assertEqual(asset.start_date, supplier_invoice.invoice_date)
    >>> assertEqual(asset.end_date,
    ...     (supplier_invoice.invoice_date + relativedelta(years=2, days=-1)))
    >>> asset.quantity
    1.0
    >>> assertEqual(asset.unit, unit)
    >>> asset.residual_value = Decimal('100')
    >>> asset.click('create_lines')
    >>> len(asset.lines)
    24
    >>> {l.depreciation for l in asset.lines}
    {Decimal('37.50')}
    >>> asset.lines[0].actual_value
    Decimal('962.50')
    >>> asset.lines[0].accumulated_depreciation
    Decimal('37.50')
    >>> asset.lines[11].actual_value
    Decimal('550.00')
    >>> asset.lines[11].accumulated_depreciation
    Decimal('450.00')
    >>> asset.lines[-1].actual_value
    Decimal('100.00')
    >>> asset.lines[-1].accumulated_depreciation
    Decimal('900.00')
    >>> asset.click('run')

Trying to close the period to check error::

    >>> period = supplier_invoice.move.period
    >>> period.click('close')
    Traceback (most recent call last):
        ...
    AccessError: ...

Create Moves for 3 months::

    >>> create_moves = Wizard('account.asset.create_moves')
    >>> create_moves.form.date = (supplier_invoice.invoice_date
    ...     + relativedelta(months=3))

Create Moves for 3 other months::

    >>> create_moves = Wizard('account.asset.create_moves')
    >>> create_moves.form.date = (supplier_invoice.invoice_date
    ...     + relativedelta(months=6))

    Decimal('0.00')

Sale the asset::

    >>> customer_invoice = Invoice(type='out')
    >>> customer_invoice.party = customer
    >>> invoice_line = InvoiceLine()
    >>> customer_invoice.lines.append(invoice_line)
    >>> invoice_line.product = asset_product
    >>> invoice_line.asset = asset
    >>> invoice_line.quantity = 1
    >>> invoice_line.unit_price = Decimal('600')
    >>> assertEqual(invoice_line.account, revenue)
    >>> customer_invoice.click('post')
    >>> customer_invoice.state
    'posted'

    Decimal('239.28')

    Decimal('239.28')

Generate the asset report::

    >>> print_depreciation_table = Wizard(
    ...     'account.asset.print_depreciation_table')
    >>> print_depreciation_table.execute('print_')

Close periods::

    >>> period.click('close')
