+Purchase Request Scenario
+=========================
+
+Imports::
+
+    >>> import datetime as dt
+    >>> from decimal import Decimal
+
+    >>> from proteus import Model, Wizard
+    >>> from trytond.modules.account.tests.tools import create_chart, get_accounts

+    >>> from trytond.tests.tools import activate_modules, assertEqual, set_user
+
+    >>> today = dt.date.today()
+
+Activate modules::
+
+    >>> config = activate_modules(
+    ...     ['purchase_request', 'stock_supply'],
+    ...     create_company, create_chart)
+
+Get accounts::
+
+    >>> accounts = get_accounts()
+    >>> expense = accounts['expense']
+
+Create parties::
+
+    >>> Party = Model.get('party.party')
+    >>> customer = Party(name='Customer')
+    >>> customer.save()
+    >>> supplier = Party(name='Supplier')
+    >>> supplier.save()
+
+Create account category::
+
+    >>> ProductCategory = Model.get('product.category')
+    >>> account_category = ProductCategory(name="Account Category")
+    >>> account_category.accounting = True
+    >>> account_category.account_expense = expense
+    >>> account_category.save()
+
+Create product::
+
+    >>> ProductUom = Model.get('product.uom')
+    >>> ProductTemplate = Model.get('product.template')
+    >>> unit, = ProductUom.find([('name', '=', 'Unit')])

+    >>> product, = template.products
+    >>> product.cost_price = Decimal('8')
+    >>> template.save()
+    >>> product, = template.products
+
+Get stock locations::
+
+    >>> Location = Model.get('stock.location')
+    >>> warehouse_loc, = Location.find([('code', '=', 'WH')])
+    >>> supplier_loc, = Location.find([('code', '=', 'SUP')])
+    >>> customer_loc, = Location.find([('code', '=', 'CUS')])
+    >>> output_loc, = Location.find([('code', '=', 'OUT')])
+    >>> storage_loc, = Location.find([('code', '=', 'STO')])
+
+Create a need for missing product::
+
+    >>> ShipmentOut = Model.get('stock.shipment.out')
+    >>> shipment_out = ShipmentOut()
+    >>> shipment_out.planned_date = today
+    >>> shipment_out.effective_date = today
+    >>> shipment_out.customer = customer
+    >>> shipment_out.warehouse = warehouse_loc
+    >>> move = shipment_out.outgoing_moves.new()
+    >>> move.product = product
+    >>> move.unit = unit
+    >>> move.quantity = 1
+    >>> move.from_location = output_loc
+    >>> move.to_location = customer_loc
+    >>> move.company = shipment_out.company
+    >>> move.unit_price = Decimal('1')
+    >>> move.currency = shipment_out.company.currency
+    >>> shipment_out.click('wait')
+
+There is no purchase request::
+
+    >>> PurchaseRequest = Model.get('purchase.request')
+    >>> PurchaseRequest.find([])
+    []
+
+Create the purchase request::
+
+    >>> create_pr = Wizard('stock.supply')
+    >>> create_pr.execute('create_')
+
+There is now a draft purchase request::
+
+    >>> pr, = PurchaseRequest.find([('state', '=', 'draft')])
+    >>> assertEqual(pr.product, product)
+    >>> pr.quantity
+    1.0
+
+Create the purchase then cancel it::
+
+    >>> create_purchase = pr.click('create_purchase')
+    >>> create_purchase.form.party = supplier
+    >>> create_purchase.execute('start')
+    >>> pr.state
+    'purchased'
+    >>> (purchase,), = create_purchase.actions
+    >>> purchase.click('cancel')
+    >>> pr.reload()
+    >>> pr.state
+    'exception'
+
+Handle the exception::
+
+    >>> handle_exception = pr.click('handle_purchase_cancellation_exception')
+    >>> handle_exception.execute('reset')
+    >>> pr.state
+    'draft'
+
+Recreate a purchase and cancel it again::
+
+    >>> create_purchase = pr.click('create_purchase')
+    >>> pr.state
+    'purchased'
+    >>> (purchase,), = create_purchase.actions
+    >>> purchase.click('cancel')
+    >>> pr.reload()
+    >>> pr.state
+    'exception'
+
+Handle again the exception::
+
+    >>> handle_exception = pr.click('handle_purchase_cancellation_exception')
+    >>> handle_exception.execute('cancel_request')
+    >>> pr.state
+    'cancelled'
+
+Re-create the purchase request::
+
+    >>> create_pr = Wizard('stock.supply')
+    >>> create_pr.execute('create_')
+
+Create a second purchase request manually::
+
+    >>> ctx = config.context
+    >>> set_user(0)  # root
+    >>> pr_id, = PurchaseRequest.create([{
+    ...             'product': product.id,
+    ...             'quantity': 1,
+    ...             'unit': unit,
+    ...             'warehouse': warehouse_loc.id,
+    ...             'origin': 'stock.order_point,-1',
+    ...             }], ctx)
+    >>> set_user()
+    >>> pr = PurchaseRequest(pr_id)
+
+There is now 2 draft purchase requests::
+
+    >>> prs = PurchaseRequest.find([('state', '=', 'draft')])
+    >>> len(prs)
+    2
+
+Create the purchase with a unique line::
+
+    >>> create_purchase = PurchaseRequest.click(prs, 'create_purchase')
+    >>> create_purchase.form.party = supplier
+    >>> create_purchase.execute('start')
+    >>> pr.state
+    'purchased'
+    >>> (purchase,), = create_purchase.actions
+    >>> len(purchase.lines)
+    1
+    >>> line, = purchase.lines
+    >>> assertEqual(line.product, product)
+    >>> line.quantity
+    2.0
+    >>> assertEqual(line.unit, unit)
+
+Create a purchase request without product::
+
+    >>> ctx = config.context
+    >>> set_user(0)  # root
+    >>> pr_id, = PurchaseRequest.create([{
+    ...             'description': "Custom product",
+    ...             'quantity': 1,
+    ...             'origin': 'stock.order_point,-1',
+    ...             }], ctx)
+    >>> set_user()
+    >>> pr = PurchaseRequest(pr_id)
+    >>> pr.save()
+
+Create the purchase without product::
+
+    >>> create_purchase = pr.click('create_purchase')
+    >>> create_purchase.form.party = supplier
+    >>> create_purchase.execute('start')
+    >>> pr.state
+    'purchased'
+
+    >>> pr.purchase_line.product
+    >>> pr.purchase_line.description
+    'Custom product'
+    >>> pr.purchase_line.quantity
+    1.0
+    >>> pr.purchase_line.unit
+    >>> pr.purchase_line.unit_price
+
+It's not possible to delete a purchase linked to a purchase_request::
+
+    >>> pr.purchase_line.purchase.delete()
+    Traceback (most recent call last):
+        ...
+    AccessError: ...
