+Imports::
+
+    >>> import datetime as dt
+    >>> from decimal import Decimal
+
+    >>> from proteus import Model, Wizard
+    >>> from trytond.modules.account.tests.tools import (

+    >>> from trytond.tests.tools import activate_modules, assertEqual
+
+    >>> today = dt.date.today()
+
+Activate modules::
+
+    >>> config = activate_modules(
+    ...     'account_invoice_defer', create_company, create_chart)
+
+    >>> Invoice = Model.get('account.invoice')
+    >>> InvoiceDeferred = Model.get('account.invoice.deferred')
+    >>> Party = Model.get('party.party')
+    >>> ProductCategory = Model.get('product.category')
+    >>> ProductUom = Model.get('product.uom')
+
+Create fiscal year::
+
+    >>> fiscalyear = set_fiscalyear_invoice_sequences(
+    ...     create_fiscalyear(today=today))
+    >>> fiscalyear.click('create_period')
+    >>> period = fiscalyear.periods[0]
+
+Get accounts::
+
+    >>> accounts = add_deferred_accounts(get_accounts())
+
+Create party::
+
+    >>> party = Party(name="Insurer")
+    >>> party.save()
+
+Create account category::
+
+    >>> account_category = ProductCategory(name="Account Category")
+    >>> account_category.accounting = True
+    >>> account_category.account_expense = accounts['expense']
+    >>> account_category.account_revenue = accounts['revenue']
+    >>> account_category.save()
+
+Create product::
+
+    >>> unit, = ProductUom.find([('name', '=', 'Unit')])
+    >>> ProductTemplate = Model.get('product.template')
+    >>> template = ProductTemplate()
+    >>> template.name = "Insurance"
+    >>> template.default_uom = unit
+    >>> template.type = 'service'
+    >>> template.list_price = Decimal('1000')
+    >>> template.account_category = account_category
+    >>> template.save()
+    >>> product, = template.products
+
+Create invoice::
+
+    >>> invoice = Invoice(type='in')
+    >>> invoice.party = party
+    >>> line = invoice.lines.new()
+    >>> line.product = product
+    >>> line.quantity = 1
+    >>> line.unit_price = Decimal('1000')
+    >>> line.defer_from = period.start_date
+    >>> line.defer_to = line.defer_from + dt.timedelta(days=499)
+    >>> invoice.invoice_date = today
+    >>> invoice.click('post')
+    >>> invoice_line, = invoice.lines
+
+Check invoice deferred and run it::
+
+    >>> deferral, = InvoiceDeferred.find([])
+    >>> assertEqual(deferral.invoice_line, invoice_line)
+    >>> deferral.amount
+    Decimal('1000.00')
+    >>> assertEqual(deferral.start_date, invoice_line.defer_from)
+    >>> assertEqual(deferral.end_date, invoice_line.defer_to)
+    >>> deferral.click('run')
+
+Check moves on invoice deferred::
+
+    >>> deferral.reload()
+    >>> deferral.state
+    'running'
+    >>> len(deferral.moves)
+    13
+    >>> accounts['deferred_expense'].reload()
+    >>> Decimal('268') <= accounts['deferred_expense'].balance <= Decimal('271')
+    True
+
+Define next fiscal year::
+
+    >>> renew_fiscalyear = Wizard('account.fiscalyear.renew')
+    >>> renew_fiscalyear.execute('create_')
+    >>> new_fiscalyear, = renew_fiscalyear.actions[0]
+
+Create moves::
+
+    >>> create_moves = Wizard('account.invoice.deferred.create_moves')
+
+Check moves on invoice deferred::
+
+    >>> deferral.reload()
+    >>> deferral.state
+    'closed'
+    >>> len(deferral.moves)
+    18
+    >>> accounts['deferred_expense'].reload()
+    >>> accounts['deferred_expense'].balance
+    Decimal('0.00')
