+@domain @cart
+Feature: Adding a new cart rule
+  In order to give the customer surcharge
+  based on the cart, we add a new rule
+  the surcharge is allowed to be more than the items total
+
+  Background:
+    Given the site operates on a store in "Austria"
+    And the site has a currency "Euro" with iso "EUR"
+    And I am in country "Austria"
+    And the site has a tax rate "AT" with "20%" rate
+    And the site has a tax rule group "AT"
+    And the tax rule group has a tax rule for country "Austria" with tax rate "AT"
+    And the site has a product "Shoe" priced at 10000
+    And the product has the tax rule group "AT"
+    And I add the product "Shoe" to my cart
+
+  Scenario: Add a new surcharge rule with 500 euro for all products
+    Given adding a cart price rule named "surcharge"
+    And the cart rule is active
+    And the cart rule is a voucher rule with code "asdf"
+    And the cart rule has a action surcharge with 500 in currency "EUR" off
+    And I apply the voucher code "asdf" to my cart
+    Then the cart discount should be "60000" including tax
+    Then the cart discount should be "50000" excluding tax
+    Then the cart total tax should be "12000"
+    Then the cart item taxes should be "12000"
+    Then the cart total should be "60000" excluding tax
+    Then the cart total should be "72000" including tax
