You want to learn more about QA automation tools. What do you do?
The DevOps Zone web page has an article entitled "Top 10 Testing Automation Tools for Software Testing." For people who are unfamiliar with QA-related technologies, they may not recognize the names of the companies behind the tools except HP. Many companies rely on HP's QA tools despite the fact that HP may sell its software development tools business unit to a different company. To learn more about QA tools themselves you may be interested in purchasing a book or two. You may also want to go Selenium's website. Another good article is this TechTarget one.
