They seem far away the days when software developers could target exactly each pixel on a Windows screen. Today, web applications run on various browsers (Chrome, Firefox, Safari, Edge, etc.) on different mobile or desktop devices with specific screen settings. This is why you need to perform cross-browser testing. This article lists the main cross-browser testing tools available today. Use our contact form to make us aware of some software testing tools that we should add to this list.

Cross-browser testing is a software testing activity that check the quality of web applications across multiple browsers, devices and operating systems. Screen size, screen resolution, OS version, browser versions, JavaScript and CSS languages support impact how your users are viewing content. Cross-browser testing helps you to understand and verify these different user experiences.

Here are some questions you should ask yourself when looking for a cross-browser testing tool:

Are you testing on real devices vs. emulators/simulators?

How many browsers, devices and operating systems are supported by the platform?

How can you test: writing your own scripts, with a record & replay tool or supporting an existing software testing framework like Selenium?

How much software testing power or which features do you need and get in the pricing plans: number of users, virtual location, testing time, parallel usage, support, external tool integration (bug tracking, continuous integration, …), analytics, etc. ?
