It doesn't look like you need to login to any of the pages above so you can drop
this.

will do

+
+  def RunPageInteractions(self, action_runner):
+    pass
+
+
+class TodoMVCPageSet(story.StorySet):

Seems like this could be PUBLIC_BUCKET since these are public pages? (You'll
need to re-upload the wpr if you change this, sorry!)

[jochen (gone - plz use gerrit), 2016/03/09 18:44:42]

will do

+
+    for name, url in URL_LIST:
+      self.AddStory(TodoMVCPage(url, self, name))
