Cross-browser testing tools are required when there is a need to test an application on multiple browsers. These tools will assist in ensuring that the web application functions correctly across all browsers. When both the server and client sides of the web application are accessed through several web browsers, this tool will be used. One can evaluate the application’s compatibility across several browsers with the help of these tools. Testing software on a single web browser isn’t always sufficient, which is why cross-browser testing techniques are necessary. The article focuses on discussing cross-browser testing.

What is Cross-Browser Testing?

Cross-browser testing tools allow testing the applications and websites end-to-end on both web and mobile across a variety of browsers. These tools are mostly cloud-based and allow you to conduct tests on browsers without installing the tool.

  • Cross-browser testing is an important part of software testing. 
  • It is a type of performance testing that allows the tester to check whether the website works as intended on all web browsers, mobile devices, and operating systems.
  • It helps to deliver a consistent user experience across different devices, browsers, platforms, etc.

Features of Cross-Browser Testing Tool

The following are some of the key features that a good cross-browser testing tool must have:

  1. Customer Support and Technical Support: The tool should have full technical support available for the users whether it’s a support team, documentation, or open-source resources.
  2. Cloud-Based: The tool should be cloud-based so that a wide range of browsers and devices are accessible. 
  3. Simple User Interface: The tool should be easy to use and navigate and the test results should be easy to view and access.
  4. Test on Browsers: The tool should have the ability to run on a multitude of browsers without the need to install those browsers.

Types of Cross-Browser Testing

  • Functional Cross-browser Testing: Make sure that every functional component of the web application functions as planned in all browsers. It guarantees that features like buttons, forms, links, and dynamic content behave consistently.
  • Effective Cross-Browser Testing: Analyze how well the web application runs in various browser versions. It examines elements including responsiveness, resource usage and website load times.
  • Cross-Browser Security Testing: Determine which security flaws may be browser-specific and fix them. It guarantees that the programme is safe and complies with security protocols on various browsers.
  • Cross-Platform Testing: Analyze the web application’s performance across various operating systems. It confirms stable operation across many operating systems, including Windows, macOS, Linux, etc.
  • Browser Version Testing: Ascertain compatibility with various browser versions. To suit individuals with varying preferences or organizations with particular browser version needs, testing is conducted on many browser versions.

Why is Cross-Browser Testing Important?

  • Erroneous display of website content: Different versions of operating systems interpret data in different ways thus some browsers may display the content of a website inappropriately, resulting in user disappointment.
  • Ensure the best user experience: Non-functional variety of web application testing can ensure every user can have the best user experience.
  • The website works properly: There should be no breaks in the layout and the website should work the same way in all browsers, OSes, or devices.
  • Speed: There is always an issue with the speed of execution when the website is tested locally across different browsers on a cloud-based testing platform.
  • Scalability: Before launching and updating the mobile application or the website one wants to see how the website appears on real devices. With cross-browser testing, it is possible to test the website in the exact environments before being alive. 
  • Multiple testing options: Almost all cross-browser testing tools offer performance testing, responsive testing, localization testing, visualization testing, etc.
  • Compatibility testing: Cross-browser testing tools that support code-less scripting make the testing process easier for non-programmers.

Benefits of Cross-Browser Testing Tools

  • Testing on multiple OS:  Cross-browser testing tools help to test web applications on multiple operating systems such as Windows, macOS, and Linux.
  • Testing on multiple browsers: Cross-browser testing tools enable testing web applications on multiple browsers.
  • Saves time: It helps to save time as there is no need to reinstall the browser multiple times.
  • Testing on varying screen resolutions: It enables testing web applications on varying screen resolutions, devices such as PCs, laptops, or mobile devices.
