Selenium, a project hosted by the Apache Software Foundation, is an umbrella open-source project comprising a variety of tools and libraries for test automation. Selenium automation framework enables QA engineers to perform automated web application testing using popular programming languages like Python, Java, JavaScript, C#, Ruby, and PHP.
Dries Buytaert, a graduate student at the University of Antwerp, came up with the idea of developing something similar to a chat room. Moreover, he modified the conventional chat rooms into a website where his friends could post their queries and reply through comments. However, for this project, he thought of creating a temporary archive of posts.
In today’s fast-paced world, the primary goal of every business is to release their application or websites to the end users as early as possible. As a result, businesses constantly search for ways to test, measure, and improve their products. With the increase in competition, faster time to market (TTM) has become vital for any business to survive in today’s market. However, one of the possible challenges many business teams face is the release cycle time, which usually gets extended for several reasons.
