-Feature: example
- In order to test DataBase Cleaner
- Here are some scenarios that rely on the DB being clean!
-
-  Background:
-    Given I have setup database cleaner to clean multiple databases using datamapper
-
-  Scenario: dirty the db
-    When I create a widget in one db using datamapper
-     And I create a widget in another db using datamapper
-    Then I should see 1 widget in one db using datamapper
-     And I should see 1 widget in another db using datamapper
-
-  Scenario: assume a clean db
-    When I create a widget in one db using datamapper
-    Then I should see 1 widget in one db using datamapper
-     And I should see 0 widget in another db using datamapper
-
-  Scenario: assume a clean db
-    When I create a widget in another db using datamapper
-    Then I should see 0 widget in one db using datamapper
-     And I should see 1 widget in another db using datamapper
