There's a huge room for improvement in my automation code here and there, but there are also some hard improvement barriers presented from using selenium webdriver. In the future, I am thinking about moving all the selenium webdriver tests to use phantomjs. I am also still using ruby 1.8.7. I hope that upgrading to ruby 2.0 will have noticeable improvement in speed.
