Having a separate code path for the test kind of defeats the purpose of the test
:)

Can you instead make a test-config.js file that you construct by hand?

[kmadhusu, 2013/07/15 22:21:51]

Fixed. Instead of modifying the codepath, I updated "configData.isGooglePage"
value in local_ntp_browsertest.js.

+    return mockTestData.isGooglePage;
+
+  return templateData.isGooglePage;
 }
