FG-0604 Cross-Platform Validation
Description
Test AI-generated artifacts across all target platforms, environments, and configurations. AI agents typically work in one environment but their output may need to function across many. Cross-Platform Validation ensures that output is tested in every context it will encounter, well beyond the development environment. This includes operating systems, browsers, screen sizes, accessibility tools, and deployment environments.
Implementation
Define the matrix of platforms and environments your output must support. Create test procedures for each platform. Automate cross-platform testing where possible. Test in the most constrained environment first: issues found there often affect all platforms. Track platform-specific issues to identify patterns.
Success Indicators
- Output functions correctly across all target platforms
- Platform-specific issues are caught before deployment
- Cross-platform testing is integrated into the regular workflow, not an afterthought
- The platform support matrix is documented and current
Failure Modes
- Testing only on the development platform: works for me syndrome
- Platform matrix too ambitious: testing more platforms than you actually support
- Automated tests that don't reflect real platform behavior
- Discovering platform issues only after deployment
