TestSquad.org discussed the fact that many people often feel confusion and have a lot of unanswered questions when they first start using Selenium RC or Selenium Grid. Many users of Selenium felt like these programs were not particularly good ones and noted that starting them on many browsers created excess overhead on the machines on which they were being run. This caused computing power to be wasted unnecessarily. Unfortunately, many people go to great lengths to be able to test with these Selenium products. It was not uncommon for people to take out personal loans or use their home equity loans for testing funds. This would often lead to bad credit and disappointment with the product as a whole.
Visitors to the site were able to weigh in with their own personal opinions on this topic. One visitor compared it to QTP for performance testing and also complained about the overhead. He felt that the programs were better suited to regression testing and functional testing and suggested that readers read is blog on finding and creating a good automated test. This particular user felt that the ability to reuse a program was more important than general performance.
Though a few users disagreed with the site's overall opinion, most agreed with the site's take on the matter. There was much debate and conversation over the best programs to use for performance testing. Overall, while no one program was actually named the best and the site itself did not take a stance, Selenium RC and Selenium Grid did not come highly recommended for performance testing except in very select cases.Even then, this was rare, and most people felt that the cons far outweighed the benefits and thus switched to other, more operable programs to meet their performance testing needs. The program was rarely reused.
