Testing tools

What are the best cross browser testing tools and why do we need to use them? The answer is simple and soon you will figure it out but so far let’s answer other questions. How often do software customers want their project to work for any user, in any environment? What is hidden behind this phrase? What exactly is required from the tester when it comes to testing? And how will he translate requirements into reality?

Today, every web developer has a task to check the site for compatibility with various browsers and their browser versions. You can, of course, install various browsers on your computer and visually check how the website displays in them. But if you are asked how many browsers you know, I think you can name at least five with confidence. And if you ask how many browsers exist at all - perhaps you will think about it. And if you ask Google about this? The answer will be confusing. The number of more or less well-known browsers now exceeds 50 items. And maybe right now someone is releasing another one on the network, their own. And let's imagine that tomorrow this “someone” will release an update to his browser. So how can one check everything in such difficult conditions? There are already many cross browser testing tools that allow you to comprehensively test a website and check how it is displayed in various browsers, on different platforms and screen resolutions.

Below we present a list of browser compatibility testing tools. These services will help you easily check your site for compatibility with any browser, from various versions of Internet Explorer to more than 300 browsers on the market in combination with different operating systems.

Cross-browser compatibility is the identity of displaying a web resource in different browsers and their versions. The incorrect look of the site pushes users away, which is bad for behavioral factors and SEO. A number of automatic web-browser testing tools allow checking cross-browser compatibility. However, some of them are paid but most of them have trial access or free plans. Choose a service that is more suitable for your workflow and check all significant design changes. In addition to the foregoing, we note that the choice of a good cross-platform tool depends on the requirements of the client and the capabilities of the product company. In addition, each browser compatibility testing tool has its advantages and disadvantages.
