os.path.join is not needed.

You can do:

file_Url = self.GetHttpURLForDataPath('pyauto_private', 'popup_blocker',
'PopupTest1.html')

+                     'PopupTest1.html'))

You could use cookie1.html from the data dir. It'll make this test faster.

+    self.SetOmniboxText(http_url)
+    self.WaitUntilOmniboxQueryDone()
+    cookie_data = self.GetCookie(pyauto.GURL(http_url))
