Install account_bank Module::

    >>> config = activate_modules('account_bank')

Create company::

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

Create fiscal year::

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

Create chart of accounts::

    >>> _ = create_chart(company)
    >>> accounts = get_accounts(company)
    >>> receivable = accounts['receivable']
    >>> revenue = accounts['revenue']
    >>> expense = accounts['expense']
    >>> cash = accounts['cash']

Create tax::

    >>> tax = create_tax(Decimal('.10'))
    >>> tax.save()

Create party::

    >>> Party = Model.get('party.party')
    >>> party = Party(name='Party')
    >>> party.save()

Create account category::

    >>> ProductCategory = Model.get('product.category')
    >>> account_category = ProductCategory(name="Account Category")

    >>> template.account_category = account_category
    >>> product, = template.products
    >>> product.cost_price = Decimal('25')
    >>> template.save()
    >>> product, = template.products

Create payment term::

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

Create payment type and link to party::

    >>> PaymentType = Model.get('account.payment.type')
    >>> payable_payment_type = PaymentType(name='Type', kind='payable')
    >>> payable_payment_type.save()
    >>> receivable_payment_type = PaymentType(name='Type', kind='receivable')
    >>> receivable_payment_type.save()
    >>> party.customer_payment_type = receivable_payment_type
    >>> party.supplier_payment_type = payable_payment_type
    >>> party.save()

Create invoice::

    >>> Invoice = Model.get('account.invoice')
    >>> InvoiceLine = Model.get('account.invoice.line')
    >>> invoice = Invoice()
    >>> invoice.party = party
    >>> invoice.payment_term = payment_term
    >>> line = InvoiceLine()
    >>> invoice.lines.append(line)
    >>> line.product = product
    >>> line.quantity = 5
    >>> line.unit_price = Decimal(40)
    >>> line = InvoiceLine()
    >>> invoice.lines.append(line)
    >>> line.account = revenue
    >>> line.description = 'Test'
    >>> line.quantity = 1
    >>> line.unit_price = Decimal(20)
    >>> invoice.untaxed_amount
    Decimal('220.00')
    >>> invoice.tax_amount
    Decimal('20.00')
    >>> invoice.total_amount
    Decimal('240.00')
    >>> invoice.payment_type == receivable_payment_type
    True
    >>> invoice.save()
    >>> Invoice.post([invoice.id], config.context)
    >>> invoice.reload()
    >>> invoice.state
    'posted'
    >>> invoice.amount_to_pay == Decimal(240)
    True

Create credit note::

    >>> Invoice = Model.get('account.invoice')
    >>> InvoiceLine = Model.get('account.invoice.line')
    >>> credit_note = Invoice()
    >>> credit_note.type = 'out'
    >>> credit_note.party = party
    >>> credit_note.payment_term = payment_term

    >>> credit_note.reload()
    >>> credit_note.state
    'posted'
    >>> credit_note.amount_to_pay == Decimal(-44)
    True


Partialy reconcile both lines::

    >>> MoveLine = Model.get('account.move.line')
    >>> lines = MoveLine.find([
    ...     ('account', '=', receivable.id)])
    >>> compensation_move = Wizard('account.move.compensation_move',
    ...     models=lines)
    >>> compensation_move.form.maturity_date = today
    >>> compensation_move.form.account = receivable
    >>> compensation_move.execute('create_move')
    >>> credit_note.reload()
    >>> credit_note.amount_to_pay
    Decimal('0.0')
    >>> invoice.reload()
    >>> invoice.amount_to_pay
    Decimal('0.0')


Create a move that pays the pending amount::

    >>> Period = Model.get('account.period')
    >>> Move = Model.get('account.move')
    >>> move = Move()
    >>> period, = Period.find([
    ...     ('start_date', '<=', today),
    ...     ('end_date', '>=', today),
    ...     ('type', '=', 'standard'),
    ...     ])
    >>> move.period = period
    >>> move.date = today
    >>> move.journal = lines[0].move.journal
    >>> line = move.lines.new()
    >>> line.account = receivable
    >>> line.credit = Decimal('196.0')
    >>> line.debit = Decimal('0.0')
    >>> line.party = party
    >>> line = move.lines.new()
    >>> line.account = cash
    >>> line.debit = Decimal('196.0')
    >>> line.credit = Decimal('0.0')
    >>> move.click('post')
    >>> invoice.reload()
    >>> invoice.amount_to_pay
    Decimal('0.0')
    >>> lines = MoveLine.find([
    ...     ('account', '=', receivable.id)])
    >>> to_reconcile = [l for l in lines if not l.reconciliation]
    >>> reconcile_lines = Wizard('account.move.reconcile_lines',
    ...     to_reconcile)
    >>> reconcile_lines.state == 'end'
    True
    >>> invoice.reload()
    >>> invoice.amount_to_pay
    Decimal('0.0')
    >>> invoice.state
    'paid'
