+Feature: Exchange rates

+  When I navigate the menu and select the item at "System > Currency > Edit rates"
+  Then I should see the Edit rates screen
+   And I should see the title "Available exchange rates"
+   And I expect the report to contain 2 rows
+   And I expect the 'Currency' report column to contain 'EUR' for Valid From '2020-01-01'
