+### JSON Memory
+
+There's one more Cucumber step that json_spec provides which hasn't been used above. It's used to

+name by which to remember it.

+      Scenario: Index action includes full user JSON
+        Given the following user exists:
+          | id | first_name | last_name |
+          | 1  | Steve      | Richert   |
+        And I visit "/users/1.json"
+        And I keep the JSON response as "USER_1"
+        When I visit "/users.json"
+        Then the JSON response should be:
+          """
