Testing a website on multiple devices involves validating behaviour, layout and performance across different screen sizes, browsers and operating systems. While manual testing is possible, it quickly becomes time-consuming and difficult to scale.
Automated cross device website testing allows teams to run repeatable tests across many device environments, ensuring consistent user experiences and reducing the risk of device-specific issues.
Cross-Device Testing Tools
Run automated tests for your app or website on any device, any browser and across any OS.
T-plan is the smart choice for code-free multi-device testing tools.
Why Choose T-Plan for Cross Device Testing?
Websites and applications are accessed across a wide range of devices, screen sizes and operating systems. Choosing the right cross device testing tool is essential to ensure consistent behaviour and a reliable user experience, regardless of how users access your application.
T-Plan supports multi device testing by interacting directly with the user interface at screen level, allowing teams to validate real user journeys across desktop and mobile environments.
With T-Plan, teams can:
- Run cross device website testing across desktops, laptops, tablets and mobile devices
- Reuse the same automation logic across multiple devices and environments
- Validate applications visually as they appear to end users, not at code level
- Reduce test maintenance for complex, legacy or frequently changing interfaces
- Scale cross-device testing efficiently without increasing manual effort
Why Run Automated Cross Device Website Testing?
Ensuring websites and applications behave correctly across multiple real devices is critical to delivering a reliable digital experience. However, with the sheer variety of phones, tablets, operating systems and screen sizes in use today, manual cross device website testing quickly becomes slow, repetitive and difficult to scale.
Using automated cross device testing makes it possible to validate functionality, layout and user interactions consistently across all device environments. This helps teams understand why a website may work on one device but not another, and resolve issues earlier in the delivery cycle.
Automated cross-device website testing enables teams to:
- Run repeatable tests across multiple devices in a fraction of the time
- Redirect tester effort towards higher-value exploratory and usability work
- Increase coverage using parallel or overnight execution with fewer resources
- Validate real end-user experience by driving applications exactly as they appear on screen
By automating how to test a website on multiple devices, teams gain confidence that users receive a consistent experience wherever they access the site.

Cross Device Testing Tool FAQs
Cross device testing is the process of validating that a website or application works correctly across multiple devices, screen sizes, operating systems and browsers. It ensures that functionality, layout and user experience remain consistent whether users access your site on a desktop, tablet or mobile device.
Many teams use a combination of browser-based tools, but effective cross-browser testing increasingly requires cross device testing software that can validate real user interactions across devices and platforms.
T-Plan supports cross-browser and cross-device testing by automating the user interface at screen level, allowing teams to test across browsers, operating systems and devices using a single, visual automation approach.
Users access websites in many different ways, and even small inconsistencies can lead to broken journeys, lost conversions or poor user satisfaction. Testing across multiple devices helps identify layout issues, usability problems and functional defects before they reach production, protecting both revenue and brand reputation.
Websites can behave differently across devices due to variations in browsers, operating systems, screen resolutions, hardware performance or touch interactions. Without proper cross device testing, these differences often go unnoticed until users encounter problems. Automated testing helps uncover these issues early by validating how applications behave in real-world device environments.
Cross-browser testing focuses on validating behaviour across different browsers, while cross device testing goes further by including different devices, screen sizes and operating systems. Together, they ensure a consistent and reliable experience for all users, regardless of how they access your website or application.
