  I create a PO
-
  !record {model: purchase.order, id: purchase_order_1}:
    partner_id: base.res_partner_1
    invoice_method: order
    order_line:
      - product_id: product.product_product_15
        price_unit: 79.80
        product_qty: 15.0
      - product_id: product.product_product_25
        price_unit: 2868.70
        product_qty: 5.0
      - product_id: product.product_product_27
        price_unit: 3297.20
        product_qty: 4.0

  I cancel the PO and create a new revision
-
   !python {model: purchase.order}: |
     po = self.browse(cr, uid, ref('purchase_order_1'))
     old_name = po.name
     self.action_cancel(cr, uid, [ref('purchase_order_1')])
     action = self.new_revision(cr, uid, [ref('purchase_order_1')])
     po.refresh()
     assert po.old_revision_ids, "Old revisions not set"
     assert po.revision_number == 1, "Revision number should be 1, %s found" % po.revision_number
     new_name = '%s-01' % old_name
     assert po.name == new_name, "New name should be %s, %s found" % (new_name, po.name)
