What are the best multi-browser testing tools?

When we write scripts for one browser, they may not necessarily run on all browsers. It’s a no-brainer. And, we all know that a few browsers can limit certain features.

For instance, if we design features that run on Safari on Mac OS, those features may not function across other browsers. To ensure the features run uniformly across various browsers and OS versions that our users have, we should perform multi-browser testing. Multi-browser scripts require stringent maintenance and updates to support niche and latest features too. 

Let us understand the importance of multi-browser testing before we proceed. As per Kinsta’s study on global browser market share, Chrome (77.03%) holds a steady share of followers, with Safari trailing next; the difference in percentage is, however, huge. with Safari at 8.87%.

Plus, there are multiple versions of operating systems and screen resolutions that our users browse content on.

According to Sweor, users take only 0.05 seconds to form an opinion on a website — and whether they’ll use it or not. The same report also states that 57 percent of the population won’t recommend a non-responsive website.

In short, user experience can take a massive hit, thereby affecting the business, if websites or web apps are not thoroughly tested before shipping. You can also check out our post on the most common issues one can face while performing browser compatibility tests.

For proper multi-browsing testing, it’s imperative to list out which browsers and OS versions we intend to test. To increase test efficacy, we must prefer testing on real-time devices as they can fetch accurate results.

Adding to all of this — picking the right tool for testing solves nearly half the problem. To help you pick the right tool, we’ll discuss the best multi-browser testing tools to check out in 2021 in this post.
