Some valuable browser testing tools.

When talking about website or web app development, one thing that developers are most concerned about is cross-browser compatibility. As you know, there are multiple things involved in creating a website, such as planning, designing, testing, etc. For developers, executing each of these tasks is crucial at every stage of web app development to ensure that users don’t face any error while browsing the website.

Most of the work related to web app can be done during the development phase to improve user experience, but cross-browser compatibility is something that can trouble you even after the website is live. For instance, let’s just say that you have tested your site compatibility across some specific browsers like Mozilla Firefox, Internet Explorer, and Chrome.

What if a user visits your website via Opera or Safari browser?

Do you think your website is compatible with other browsers as well? And if it is not, do you think users will revisit your site?

Due to the lack of your site’s browser compatibility, you can lose on a lot of user traffic, which might result in less return on investment. Thus, it is vital to test your web app across all those browsers that users can use to access your website.

What Does Cross-Browser Compatibility Mean?

Multiple explanations of cross-browser testing are available across the internet, and all of them are true in their way. In our opinion, we believe that verifying the functionality of a web app or website across all the related browsers, operating systems, and devices to ensure it provides a common user experience on every platform is considered as cross-browser compatibility testing. Now, there are multiple metrics involved in it, such as:

  • Performance – Ensuring optimal web performance on all platforms.
  • Code validation – Ensuring that the JavaScript and CSS validate appropriately across all browsers.
  • User interface – Checking whether the web UI matches as per your expectations or not.
  • Behavior – Providing the same user experience throughout the website like navigation, dialog boxes, links, etc.

Most of you might be thinking, is it necessary to test the website across all the browsers, and if it is, then how much time would it take to test all the browsers, OS, and devices?

First of all, the list of browsers, operating systems, and devices are too long, so testing every browser+OS combination doesn’t make sense; however, you will have to do your research to find out what browsers and devices users uses the most to access your website.

Even after finalizing a list of browsers, OS, and devices, it is not easy to test every combination manually because it requires a lot of resources, efforts, and most importantly — time. So, there are browser testing tools for developers to ease the process of cross-browser compatibility testing.

Here, we will take a look at the top seven browser testing tools for developers available in 2019.
