Panel Discussion: The Future Of Testing [Testμ 2022]

In the tech sector, we have heard and occasionally still hear these phrases: “Testing will soon be extinct!”, “Testing can be automated”, or “Who even needs testers?”. But don’t sweat, the testing craft has a promising future as long as the software is available on our planet. But what will testing look like in the future?

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.

How To Generate HTML Reports With WebdriverIO?

Reporting is an inevitable factor in any test automation framework. A well-designed and developed framework should not just let you write the test cases and execute them, but it should also let you generate the report automatically. Such frameworks allow us to run the entire test scripts and get reports for the complete project implementation rather than for the parts separately. Moreover, it contributes to the factors that determine the decision to choose a framework for Selenium automation testing.

Top 11 JavaScript Frameworks For 2019

An extensive number of programming languages are being used worldwide today, each having its own purpose, complexities, benefits and quirks. However, it is JavaScript that has without any doubt left an indelible and enduring impression on the web, to emerge as the most popular programming language in the world for the 6th consecutive year.

Why You Should Use Puppeteer For Testing

Over the past decade the world has seen emergence of powerful Javascripts based webapps, while new frameworks evolved. These frameworks challenged issues that had long been associated with crippling the website performance. Interactive UI elements, seamless speed, and impressive styling components, have started co-existing within a website and that also without compromising the speed heavily. CSS and HTML is now injected into JS instead of vice versa because JS is simply more efficient. While the use of these JavaScript frameworks have boosted the performance, it has taken a toll on the testers.
