What Is A Cross Browser Testing Tool?
Manually testing your web application in different browsers is time-consuming and inefficient. That’s where cross-browser testing tools come into play. These tools are designed to test multiple browsers simultaneously. This improves user experience and assures consistency across different browsers.
Why Do You Need A Cross Browser Testing Tool?
Cross-browser testing tools allow you to test your application across various browser combinations, ensuring it works consistently and as expected. They also help to perform compatibility testing at scale and troubleshoot bugs in your website and apps when visited through various devices and browsers.
A multi-browser testing tool helps with compatibility testing at scale – without requiring infrastructure setup from your end. It will help you troubleshoot bugs in your website and apps when visited through various devices and browsers.
Compatibility Testing
Cross Browser testing tools that support code-less scripting make this process easier for non-programmers. For example, being able to write your script in English and help create browser-agnostic tests in a jiffy, so you don’t have to account for individual webdriver implementation differences in popular browsers before writing or executing your tests.
Speed
When you test locally hosted apps across different browsers on a cloud-based testing platform, there’s always the issue of speed of execution. For a large enterprise, you can expect a complex test scenario to take hours. This issue is common to all popular cloud-based testing platforms.
