Execute tests across cloud infrastructure, local devices, or real devices, giving teams the flexibility to test anywhere

Scale Cross-Device Testing with
Agentic AI and No-Code

Testing across browsers, devices, and platforms becomes complex as applications grow and release cycles accelerate. Testsigma simplifies cross-device testing with Agentic AI, no-code automation, and flexible cloud and local execution environments.

Identify Critical Device &
Browser Coverages

Use AI Agents to identify high-risk device, browser, and OS combinations based on your application usage. Convert these insights into a focused cross-device testing strategy that ensures real user environments are covered.

Create Tests Without
Coding

Build cross-device automated tests using the Generator Agent, NLP steps, Record, and data-driven inputs without writing scripts. AI assistance accelerates test creation while keeping tests easy to update as your application evolves.

Validate Mobile and Web
Experiences

Test web and native mobile apps across browsers, operating systems, and device configurations. Use Mobile Inspector, OTP handling, and emulator or simulator environments to validate real user journeys.

Run Tests in Parallel Across
Devices

Scale cross-device testing with parallel executions across browsers, mobile devices, and platforms. Testsigma supports large-scale testing across thousands of devices and browser combinations without slowing release cycles.

Keep Tests Stable with
Auto-Healing

Reduce maintenance with AI-powered auto-healing that adapts to UI changes automatically. This keeps cross-device tests stable across browsers and devices, even as your application evolves.

Frequently Asked Questions

Why is cross-device testing important for product quality?

Users access applications from many browsers, devices, and operating systems. Cross-device testing ensures that features, layouts, and workflows behave consistently across these environments, helping teams avoid device-specific bugs that could impact real users.

Which devices and browsers should be prioritized in cross-device testing?

Start with the browsers, operating systems, and devices most used by your customers. Analytics data can help identify the combinations that matter most, allowing teams to focus testing on high-impact environments first.

What is the difference between cross-browser testing and cross-device testing?

Cross-browser testing validates how an application behaves across different browsers, while cross-device testing verifies functionality across devices, operating systems, and screen sizes. Cross-device testing typically includes cross-browser testing as part of broader environment coverage.

Can cross-device testing be automated?

Yes, cross-device testing can be automated using test automation frameworks or platforms that support running tests across multiple devices and browsers. Automated tests help teams validate the same user flows consistently across many environments.

When should cross-device tests run in the development cycle?

Cross-device tests should run during continuous integration and before releases to ensure critical workflows work across supported devices and browsers. Many teams also schedule regular regression runs to maintain broader environment coverage.

What challenges are common in cross-device testing?

Common challenges include device fragmentation, browser-specific behavior, UI layout differences across screen sizes, and maintaining test environments. Using automation and device clouds helps teams manage these challenges more efficiently.

How does parallel execution help in cross-device testing?

Parallel execution allows the same test suite to run simultaneously across multiple devices and browsers. This significantly reduces test cycle time and helps teams validate more environments without slowing down release pipelines.
