Different Ways To Style CSS Box Shadow Effects

Have you ever visited a website that only has plain text and images? Most probably, no. It’s because such websites do not exist now. But there was a time when websites only had plain text and images with almost no styling. For the longest time, websites did not focus on user experience. For instance, this is how eBay’s homepage looked in 1999.

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.

New Year Resolutions Of Every Website Tester In 2020

Were you able to work upon your resolutions for 2019? I may sound comical here but my 2019 resolution being a web developer was to take a leap into web testing in my free time. Why? So I could understand the release cycles from a tester’s perspective. I wanted to wear their shoes and see the SDLC from their eyes. I also thought that it would help me groom myself better as an all-round IT professional.
