- 12. 1/28/2013 12 About Neustar: • Among other services, Neustar offers cloud-based load testing.
- 13. 1/28/2013 13 Why choose cloud-based load testing? • Identify bottlenecks/unusual performance issues before going live. • Local load testing adds unnecessary load to network/cpu. • Local load tests originate in one location.
- 14. 1/28/2013 14 What does Neustar have to offer? • Real browser tests Browser: Firefox Asynchronous calls included or blacklisted Screen shots, video playback of failures • Basic tests Headless Http client Ideal for testing web services 10x cheaper than real browser tests Direct Http calls, faster performance

- 18. 1/28/2013 18 Gotchas • File based test resources are unreliable. • Limited script size (Too many instructions exception). • Limited client-side SSL support. • Heap size issues running basic tests.
- 19. 1/28/2013 19 Gotchas • No failure pagination (Large failure list causes logging page to become unresponsive). • Firefox-only in browser tests (Chrome support on 2013 roadmap). • Number of available agents dependent on origin datacenter (eg: more in DC than Oregon). • Too many pauses/waits can cause transaction to fail.
