Top Programming Languages Helpful For Testers

There are many debates going on whether testers should know programming languages or not. Everyone has his own way of backing the statement. But when I went on a deep research into it, I figured out that no matter what, along with soft skills, testers must know some programming languages as well. Especially those that are popular in running automation tests.

Selenium C# Tutorial: Introduction

As per, Stack Overflow Annual Developer Survey 2019, C# is one of the most loved programming languages with 67% and is also deemed to be one of the most popular languages with 31% votes from all the respondents.

23 Node.js Best Practices For Automation Testing

If you are in the world of software development, you must be aware of Node.js. From Amazon to LinkedIn, a plethora of major websites use Node.js. Powered by JavaScript, Node.js can run on a server, and a majority of devs use it for enterprise applications. As they consider it a very respectable language due to the power it provides them to work with. And if you follow Node.js best practices, you can increase your application performance on a vast scale.

Cypress vs Selenium – Which Is Better ?

Selenium is one of the most prominent automation frameworks for functional testing and web app testing. Automation testers who use Selenium can run tests across different browser and platform combinations by leveraging an online Selenium Grid, you can learn more about what Is Selenium? Though Selenium is the go-to framework for test automation, Cypress – a relatively late entrant in the test automation game has been catching up at a breakneck pace.
