                                                 Selenium As I have mentioned I am trying to explore the selenium. So I will more talk about selenium web driver or   selenium 2.0. Other topics like Selenium history and RC, touch and go manner!! Let’s start.... Selenium is an open source test automation suite used for automating web-based applications. It supports automation across different browsers, platforms and programming languages. Benefits:           Selenium is open source, there is no licensing cost for its usage.           Scripting can be done in most of the widely used programming languages like Java, C#, Ruby and Python           It supports most of the popular browser...

                                          Automation Testing Let’s talk about another aspect of Automation Testing. I am trying to explore selenium. I believe, one of the best ways to learn it, learn and share Here I am starting with basics post on Automation testing, general topics and I will move to selenium tool exploration along with you guys. What is Automation Testing A  p rocess of validating and verifying whether the software program works as expected using any automation tool How Automation testing is different from Performance testing? Since I am Performance tester so first question come in my mind is the difference in both approach. The basic difference is in the verification  and assertions done in the two different test types.  In Automation Testing the verification  and assertions done are all oriented to validati...

                                      Regular Expression in Performance Testing Regular Expression is the most effective way to handle dynamic response in performance testing. As we know regular expression is pattern based mathematical calculation. Regular expressions or regex or regexp are extremely useful in extracting information from any text by searching for one or more matches of a specific search pattern Regular expressions, as a concept, was founded by Stephen Kleene , best known as the founder of the piece of mathematical logic known as recursion theory How to   learn about RegEx ? With RegEx, we don’t really understand them until we use them, and we can’t really use them until we understand them. So, we must learn a little bit, and then use a little bit and get them wrong, and then go back to the concepts and learn a little bit more. In layman’s lang...

                               90% Percentile in Performance Testing Let’s talk about performance testing concept in general. One of the most important concepts which we always come across after completing load test is 90% Percentile Response time. What is Percentile? Let’s say 60% of people are shorter than you: percentile 60%. That means you are at the 60th percentile. i.e. Percentile relates to where an individual item stands within a population/a bulk of data set. Now we come to 90%Percentile Let’s consider an example: We execute a load test of 20 iterations. We captured the response times of 20 iterations as below: No. Iteration No. Login (Response Time) 1 1 0.8 2 2 1.5 3 3 1.8 4 4 1.1 5 5 1.6 6 6...
