+Payment Planning Scenario
+=========================
+
+Imports::
+
+    >>> import datetime as dt
+    >>> from decimal import Decimal
+
+    >>> from proteus import Model, Wizard
+    >>> from trytond.modules.account.tests.tools import (
+    ...     create_chart, create_fiscalyear, get_accounts)
+    >>> from trytond.modules.company.tests.tools import create_company
+    >>> from trytond.tests.tools import activate_modules, assertEqual
+
+    >>> today = dt.date.today()
+    >>> tomorrow = today + dt.timedelta(days=1)
+    >>> next_week = today + dt.timedelta(weeks=1)
+
+Activate modules::
+
+    >>> config = activate_modules('account_payment', create_company, create_chart)
+
+Create fiscal year::
+
+    >>> fiscalyear = create_fiscalyear(today=(today, next_week))
+    >>> fiscalyear.click('create_period')
+
+Get accounts::
+
+    >>> accounts = get_accounts()
+    >>> payable = accounts['payable']
+    >>> expense = accounts['expense']
+
+    >>> Journal = Model.get('account.journal')
+    >>> expense_journal, = Journal.find([('code', '=', 'EXP')])
+
+Create payment journal::
+
+    >>> PaymentJournal = Model.get('account.payment.journal')
+    >>> payment_journal = PaymentJournal(name='Manual',
+    ...     process_method='manual')
+    >>> payment_journal.save()
+
+Create parties::
+
+    >>> Party = Model.get('party.party')
+    >>> supplier = Party(name='Supplier')
+    >>> supplier.save()
+
+Create payable move::
+
+    >>> Move = Model.get('account.move')
+    >>> move = Move()
+    >>> move.journal = expense_journal
+    >>> line = move.lines.new(account=payable, party=supplier,
+    ...     credit=Decimal('50.00'), maturity_date=next_week)
+    >>> line = move.lines.new(account=expense, debit=Decimal('50.00'))
+    >>> move.click('post')
+
+Paying the line without date uses the maturity date::
+
+    >>> Payment = Model.get('account.payment')
+    >>> line, = [l for l in move.lines if l.account == payable]
+    >>> pay_line = Wizard('account.move.line.pay', [line])
+    >>> pay_line.execute('next_')
+    >>> pay_line.execute('next_')
+    >>> payment, = Payment.find()
+    >>> assertEqual(payment.date, next_week)
+
+The date on the payment wizard is used for payment date::
+
+    >>> payment.delete()
+    >>> pay_line = Wizard('account.move.line.pay', [line])
+    >>> pay_line.form.date = tomorrow
+    >>> pay_line.execute('next_')
+    >>> pay_line.execute('next_')
+    >>> payment, = Payment.find()
+    >>> assertEqual(payment.date, tomorrow)
