+==============================
+
+Imports::
+
+    >>> from decimal import Decimal
+
+    >>> from proteus import Model
+    >>> from trytond.modules.account.tests.tools import create_chart, get_accounts
+    >>> from trytond.modules.company.tests.tools import create_company
+    >>> from trytond.tests.tools import activate_modules
+
+Activate modules::
+
+    >>> config = activate_modules(
+    ...     'sale_promotion_coupon', create_company, create_chart)
+
+Get accounts::
+
+    >>> accounts = get_accounts()
+    >>> revenue = accounts['revenue']
+
+Create customer::
+
+    >>> Party = Model.get('party.party')
+    >>> customer = Party(name='Customer')
+    >>> customer.save()
+
+Create account category::
+
+    >>> ProductCategory = Model.get('product.category')
+    >>> account_category = ProductCategory(name="Account Category")
+    >>> account_category.accounting = True
+    >>> account_category.account_revenue = revenue
+    >>> account_category.save()
+
+Create products::
+
+    >>> ProductUom = Model.get('product.uom')
+    >>> ProductTemplate = Model.get('product.template')
+    >>> Product = Model.get('product.product')
+    >>> unit, = ProductUom.find([('name', '=', 'Unit')])
+    >>> template = ProductTemplate()
+    >>> template.name = 'Product'
+    >>> template.default_uom = unit
+    >>> template.type = 'goods'
+    >>> template.salable = True
+    >>> template.list_price = Decimal('20')
+    >>> template.account_category = account_category
+    >>> template.save()
+    >>> product, = template.products
+
+Create Promotion with coupon::
+
+    >>> Promotion = Model.get('sale.promotion')
+    >>> promotion = Promotion(name="10%")
+    >>> promotion.formula = '0.9 * unit_price'
+    >>> coupon = promotion.coupons.new()
+    >>> coupon.number_of_use = 0
+    >>> number = coupon.numbers.new(number="CODE10")
+    >>> promotion.save()
+
+Sale without promotion coupon::
+
+    >>> Sale = Model.get('sale.sale')
+    >>> sale = Sale()
+    >>> sale.party = customer
+    >>> sale_line = sale.lines.new()
+    >>> sale_line.product = product
+    >>> sale_line.quantity = 5
+    >>> sale.save()
+    >>> sale.untaxed_amount
+    Decimal('100.00')
+    >>> sale.click('quote')
+    >>> sale.untaxed_amount
+    Decimal('100.00')
+
+Add promotion coupon to the sale::
+
+    >>> sale.click('draft')
+    >>> sale.coupons.extend(sale.coupons.find([('rec_name', '=', 'CODE10')]))
+    >>> len(sale.coupons)
+    1
+    >>> sale.save()
+    >>> sale.untaxed_amount
+    Decimal('100.00')
+    >>> sale.click('quote')
+    >>> sale.untaxed_amount
+    Decimal('90.00')
+
+Check coupon inactive after usage::
+
+    >>> Number = Model.get('sale.promotion.coupon.number')
+    >>> coupon, = promotion.coupons
+
+    >>> number, = Number.find([('rec_name', '=', 'CODE10')])
+    >>> bool(number.active)
+    True
+
+    >>> with config.set_context(party=customer.id):
+    ...     number_party, = Number.find([('rec_name', '=', 'CODE10')])
+    >>> bool(number_party.active)
+    True
+
+    >>> coupon.number_of_use = 1
+    >>> coupon.save()
+    >>> number.reload()
+    >>> bool(number.active)
+    False
+    >>> Number.find([('rec_name', '=', 'CODE10')])
+    []
+    >>> number_party.reload()
+    >>> bool(number_party.active)
+    False
+    >>> with config.set_context(party=customer.id):
+    ...     Number.find([('rec_name', '=', 'CODE10')])
+    []
+
+Cancel sale remove the coupons::
+
+    >>> sale.click('cancel')
+    >>> len(sale.coupons)
