Top Browsers for Cross-Browser Testing in 2020

We all know that user experience matters; it’s the key to delighting our customers. So, whether you are managing a live website or building a new one, you need to ensure a uniform user experience across all browsers and browser versions. Since web browsers don’t render the websites the same way, it becomes essential to perform cross-browser testing and check website compatibility on different browsers.

By performing cross-browser testing, you can ensure that the website behaves as intended across all the browsers. A website comprises the latest web technologies and languages such as HTML, CSS, Python, SQL, PHP, and JavaScript. All these web techs combine to give a complete look and function of the website. When these websites run on different web browsers, browsers execute the website code and display it to the users. But each browser interacts with websites uniquely and interprets the web components based on their arrangement to represent the website accordingly.

Guide To Cross Browser Testing On Older Browser Versions

“How do I perform website testing on older browser versions? Is it even necessary?”

Have you ever wondered about these questions? If you did, you’re not the only one. At some point, every web tester or web developer ponders on these. And it is logical to do so. After all, new browser versions are released every month. Which makes it difficult for testers and developers to maintain a record of emerging and deprecated features. Not to forget, the never-ending release requirements are constantly squeezing your bandwidth.

WebSockets vs. Long Polling

Sometimes we need information from our servers as soon as it’s available. The usual AJAX request/response we’re all used to doesn’t keep the connection open for this sort of use case. Instead, we need a push-based method like WebSockets, long polling, server-sent events (SSE), or, the more recently created, HTTP2 push. In this article, we compare two methods: WebSockets and long polling.

An Overview of Long Polling

In 1995, Netscape Communications hired Brendan Eich to implement scripting capabilities in Netscape Navigator and, over a ten-day period, the JavaScript language was born. Its capabilities as a language were initially very limited compared to modern-day JavaScript, and its ability to interact with the browser’s document object model (DOM) was even more limited. JavaScript was mostly useful for providing limited enhancements to enrich document consumption capabilities. For example, in-browser form validation and lightweight insertion of dynamic HTML into an existing document.
