+Feature: Rerun campaigns
+
+  Background:
+    Given I am signed in as the API user
+
+  Scenario: Rerun campaign button queues correctly
+    Given I have a campaign "brian"
+    And that campaign has 5 certificates
+    And I visit the campaign page for "brian"
+    Then the campaign should be queued to be rerun
+    When I click "Rerun campaign"
+    And I should be redirected to the campaign page for "brian"
+    And I should see "Campaign queued for rerun"
+
+  Scenario: Rerunnning campaigns when new data is present
+    Given I want to create a certificate via the API
+    And I apply a campaign "brian"
+    And the field "publisherUrl" is missing from my metadata
+    And my URL autocompletes via DataKitten
+    When I request a certificate via the API
+    And the certificate is created
+    And I visit the campaign page for "brian"
+    When I add the field "publisherUrl" with the value "http://example.com" to my metadata
+    And my URL autocompletes via DataKitten
+    And I click "Rerun campaign"
+    Then I should see "1 certificate published"
