+Feature: dc / kvs / trailing slash
+  Scenario: I have 10 folders
+    Given 1 datacenter model with the value "datacenter"
+    And 10 kv models from yaml
+    When I visit the kvs page for yaml
+    ---
+      dc: datacenter
+      kv: foo/bar
+    ---
+    Then the url should be /datacenter/kv/foo/bar
+    And the last GET request was made to "/v1/kv/foo/bar/?keys&dc=datacenter&separator=%2F"
