+Account Tax Code Scenario
+=========================
+
+Imports::
+
+    >>> from decimal import Decimal
+
+    >>> from proteus import Model, Wizard
+    >>> from trytond.modules.account.tests.tools import (
+    ...     create_chart, create_fiscalyear, create_tax, create_tax_code, get_accounts)
+    >>> from trytond.modules.company.tests.tools import create_company
+    >>> from trytond.tests.tools import activate_modules
+
+Activate modules::
+
+    >>> config = activate_modules('account', create_company, create_chart)
+
+Create fiscal year::
+
+    >>> fiscalyear = create_fiscalyear()
+    >>> fiscalyear.click('create_period')
+    >>> period = fiscalyear.periods[0]
+
+Get accounts::
+
+    >>> accounts = get_accounts()
+
+Create tax code::
+
+    >>> TaxCode = Model.get('account.tax.code')
+    >>> tax = create_tax(Decimal('0.1'))
+    >>> tax.save()
+    >>> base_code = create_tax_code(tax, amount='base')
+    >>> base_code.save()
+    >>> tax_code_invoice = create_tax_code(tax)
+    >>> tax_code_invoice.save()
+    >>> tax_code_credit = create_tax_code(tax, type='credit')
+    >>> tax_code_credit.save()
+
+Create parties::
+
+    >>> Party = Model.get('party.party')
+    >>> party = Party(name='Party')
+    >>> party.save()
+
+Create some moves::
+
+    >>> Journal = Model.get('account.journal')
+    >>> Move = Model.get('account.move')
+    >>> journal, = Journal.find([
+    ...         ('code', '=', 'EXP'),
+    ...         ])
+
+    >>> move = Move(period=period, journal=journal)
+    >>> move.date = period.start_date
+    >>> line = move.lines.new()
+    >>> line.account = accounts['expense']
+    >>> line.credit = Decimal(10)
+    >>> line = move.lines.new()
+    >>> line.account = accounts['payable']
+    >>> line.debit = Decimal(11)
+    >>> line.party = party
+    >>> line = move.lines.new()
+    >>> line.account = accounts['tax']
+    >>> line.credit = Decimal(1)
+    >>> tax_line = line.tax_lines.new()
+    >>> tax_line.amount = line.credit
+    >>> tax_line.type = 'tax'
+    >>> tax_line.tax = tax
+    >>> move.save()
+
+    >>> _ = move.duplicate()
+
+    >>> cancel_move = Wizard('account.move.cancel', [move])
+    >>> cancel_move.form.reversal = False
+    >>> cancel_move.execute('cancel')
+
+Check tax code::
+
+    >>> TaxCode = Model.get('account.tax.code')
+
+    >>> with config.set_context(periods=[period.id]):
+    ...     tax_code_invoice = TaxCode(tax_code_invoice.id)
+    ...     tax_code_credit = TaxCode(tax_code_credit.id)
+    >>> tax_code_invoice.amount, tax_code_credit.amount
+    (Decimal('1.00'), Decimal('0.00'))
