When working with tests that run across multiple platforms (iOS, Android, etc.), ensure proper configuration and handling of platform-specific issues: 1. Place test files in all relevant platform-specific directories to ensure they're properly recognized: ``` metrics/linux-gcc8-release/render-tests/... ios-render-test-runner/... android-render-test-runner/... ``` 2. When excluding a test that fails on specific platforms: - Document the reason for exclusion with a clear comment or issue link - Specify the exclusion only for affected platforms when possible - Create a follow-up issue to investigate and fix the root cause 3. For inconsistent test results that vary by device or environment: - Document the specific conditions where failures occur - Consider conditional test execution rather than complete exclusion This approach maintains test coverage across platforms while providing clear documentation for temporarily disabled tests.
