This file is missing a command to add an extension to the extensions_to_load.
Right now, its assuming (Requiring) that the user pass them in via the command
line.

Something like

   extension_to_load = ExtensionToLoad(os.path.join(os.path.dirname(__file__),
 unittestdatadir, 'extension_test')))

+  options, args = parser.parse_args(args)
+
+  browser_to_create = telemetry.FindBrowser(options)
+  assert browser_to_create
+  with browser_to_create.Create() as b:
+    ext = b.extensions.FindByUrl(
+        'chrome-extension://aapnijgdinlhnhlmodcfapnahmbfebeb/' +

this part bugs me --- we're hand-coding in the extension id. We should figure
out a way to get the extension id before we load it. Ideally, we'd add an id
getter property on extension and then do extension_to_load.id?
