## What Cross-Browser Testing Tools Do

- Run the same test across multiple browsers, versions, devices, and operating systems
- Catch rendering and functional inconsistencies before users encounter them
- Provide real-device or emulator-based coverage at scale
- Support parallel execution to keep test suites fast as coverage grows
- Integrate with CI/CD pipelines for automated cross-browser regression checks
