selenium testing & sauceThis is part 5 of 8 in a mini series of follow-up Q&A’s from Selenium expert Dave Haeffner. Read up on the firstsecondthird, and fourth. Dave discussed  how to build out a well factored, maintainable, resilient, and parallelized suite of tests that run locally, on a Continuous Integration system, and in the cloud in our recent webinar, "Selenium Bootcamp". Following the webinar, there were several follow-up questions. Dave's agreed to respond to 8. Below you’ll find the fourth Q&A. Stay tuned next Wednesday for the next question.

5. ­Is Selenium Grid still relevant/useful for parallelization? ­

Selenium Grid is a great option for scaling your test infrastructure if you're okay with handling the overhead of spinning up/maintaining a bunch of machines. It, by itself, will not give you parallelization. That is to say, it can handle however many connections you throw at it, but you will still need to find a way to execute your tests in parallel. You can learn more about Selenium Grid on it's project main page. -Dave Haeffner, April 9, 2014
