Not sure what this block is for.  Some clarification would be great.

[Jamie, 2015/01/08 23:43:08]

I originally had some code here to click the "sign in" button and continue with
other tests. Unfortunately, there's a bug in the sign-in code that assumes apps
v1, so I removed it, but forgot to remove this block.

+        return Promise.resolve();
+      }
+  ).then(
+      function(value) {

value is unused, consider removing?

+        return browserTest.pass(value);
+      },
+      function(error) {
+        return browserTest.fail(error);
+      }
+  );
+};
+
+// Set a valid access token, then re-authenticate. Note that we're not
+// trying to test the sign-in flow here (that's tested elsewhere), we're
+// just getting the app back into a signed-in state so that we can continue
+// to test its behaviour if the token becomes invalid at various stages.

+  remoting.mockIdentity.setAccessToken(
+      remoting.MockIdentity.AccessToken.VALID);
