Chrome is currently the dominating browser with around 67.53% of market share as of Nov 2024, but if you only test your websites on Chrome, there is still around 32.47% of your users who visit your site on other browsers that you are missing out on.
What if a bug occurs on those browsers? To ensure that no bugs went undetected, you need cross-browser testing.
To test across browsers, you may need a cross-browser testing tool. Without such tools, you need to constantly switch from one browser/device/OS to the next for the same test case.
In this article, we have listed down the top cross-browser testing tools for your QA team to consider. Make sure to choose a tool that aligns best with your team's needs, resources, and technical expertise.
Benefits of Adopting a Cross-browser Testing Tool
Cross-browser testing is just one aspect of the broader scope of cross-platform testing, which evaluates software across combinations of browsers, operating systems, devices, and their legacy versions. The landscape includes:
- 9000+ devices
- 21 operating systems (with older versions)
- 6 major browser engines (e.g., Blink, WebKit, Gecko) powering thousands of browsers like Chrome, Firefox, and Safari.
These variables create thousands of device-OS-browser combinations to test for compatibility and performance.
Upon adopting a cross-browser testing tool, you can see these benefits:
- Improved coverage as you gain access to thousands of browsers, devices, and OS to test on.
- Time and cost efficiency as setting up and maintaining an in-house device lab is really costly.
- Parallel testing capabilities to reduce the time spent on regression testing
- Seamless integration with CI/CD systems (Jenkins, GitLab, Azure) to enable automated checks during software builds for faster feedback.
