+================================

+Imports::
+
+    >>> from decimal import Decimal
+
+    >>> from proteus import Model, Wizard
+    >>> from trytond.modules.account.tests.tools import (
+    ...     create_chart, create_fiscalyear, get_accounts)

+    ...     set_fiscalyear_invoice_sequences)
+    >>> from trytond.modules.company.tests.tools import create_company
+    >>> from trytond.tests.tools import activate_modules
+
+Activate modules::
+
+    >>> config = activate_modules('account_invoice', create_company, create_chart)
+
+    >>> Party = Model.get('party.party')
+    >>> ProductCategory = Model.get('product.category')
+    >>> ProductUom = Model.get('product.uom')
+    >>> ProductTemplate = Model.get('product.template')
+    >>> Invoice = Model.get('account.invoice')
+    >>> Warning = Model.get('res.user.warning')
+
+Create fiscal year::
+
+    >>> fiscalyear = set_fiscalyear_invoice_sequences(
+    ...     create_fiscalyear())
+    >>> fiscalyear.click('create_period')
+
+Get accounts::
+
+    >>> accounts = get_accounts()
+
+Create party::
+
+    >>> party = Party(name="Party")
+    >>> 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')])
+    >>> template = ProductTemplate()
+    >>> template.name = 'product'
+    >>> template.default_uom = unit
+    >>> template.type = 'service'
+    >>> template.list_price = Decimal('40')
+    >>> template.account_category = account_category
+    >>> template.save()
+    >>> product, = template.products
+
+Create invoice::
+
+    >>> invoice = Invoice()
+    >>> invoice.party = party
+    >>> line = invoice.lines.new()
+    >>> line.product = product
+    >>> line.quantity = 5
+    >>> line.unit_price = Decimal('40')
+
+Post invoice and cancel the created move::
+
+    >>> invoice.click('post')
+    >>> invoice.state
+    'posted'
+    >>> cancel_move = Wizard('account.move.cancel', [invoice.move])
+    >>> cancel_move.form.description = 'Cancel'
+    >>> cancel_move.execute('cancel')
+    Traceback (most recent call last):
+        ...
+    CancelInvoiceMoveWarning: ...
+
+Bypass the warning and cancel the move::
+
+    >>> try:
+    ...     cancel_move.execute('cancel')
+    ... except CancelInvoiceMoveWarning as warning:
+    ...     Warning(user=config.user, name=warning.name).save()
+    >>> cancel_move.execute('cancel')
+    >>> cancel_move.state
+    'end'
+
+    >>> invoice.reload()
+    >>> [bool(l.reconciliation) for l in invoice.move.lines
+    ...     if l.account == accounts['receivable']]
+    [True]
+    >>> invoice.state
+    'paid'
