What is Selenium Grid & Advantages of Selenium Grid

Manual cross browser testing is neither efficient nor scalable as it will take ages to test on all permutations & combinations of browsers, operating systems, and their versions. Like every developer, I have also gone through that ‘I can do it all phase’. But if you are stuck validating your code changes over hundreds of browsers and OS combinations then your release window is going to look even shorter than it already is. This is why automated browser testing can be pivotal for modern-day release cycles as it speeds up the entire process of cross browser compatibility.

A Reconsideration of Software Testing Metrics

There is just one area where each member of the software testing community has a distinct point of view! Metrics! This contentious issue sparks intense disputes, and most conversations finish with no definitive conclusion. It covers a wide range of topics: How can testing efforts be measured? What is the most effective technique to assess effectiveness? Which of the many components should be quantified? How can we measure the quality of our testing performance, among other things?

Why Selenium WebDriver Should Be Your First Choice for Automation Testing

Developed in 2004 by Thoughtworks for internal usage, Selenium is a widely used tool for automated testing of web applications. Initially, Selenium IDE(Integrated Development Environment) was being used by multiple organizations and testers worldwide, benefits of automation testing with Selenium saved a lot of time and effort. The major downside of automation testing with Selenium IDE was that it would only work with Firefox. To resolve the issue, Selenium RC(Remote Control) was used which enabled Selenium to support automated cross browser testing.
