Selenium is still the most influential and well-developed framework for web automation testing. Being one of the best automation frameworks with constantly evolving features, it is poised to lead the industry in all aspects as compared to other trending frameworks like Cypress, Puppeteer, PlayWright, etc. Furthermore, using Selenium gives you the flexibility to use different programming languages like C#, Ruby, Perl, Java, Python, etc., and also accommodate different operating systems and web browsers for Selenium automation testing.
JavaScript is one of the most widely used programming languages. This popularity invites a lot of JavaScript development and testing frameworks to ease the process of working with it. As a result, numerous JavaScript testing frameworks can be used to perform unit testing.
We were eager to listen to Manoj Kumar, VP Developer Relations, LambdaTest, speak on the importance of Selenium 4.0 and how bright the future is. This was the agenda of the speech:
In today’s data-driven world, the ability to access and analyze large amounts of data can give researchers, businesses & organizations a competitive edge. One of the most important & free sources of this data is the Internet, which can be accessed and mined through web scraping.
LambdaTest’s Playwright tutorial will give you a broader idea about the Playwright automation framework, its unique features, and use cases with examples to exceed your understanding of Playwright testing. This tutorial will give A to Z guidance, from installing the Playwright framework to some best practices and advanced concepts.
