When to Use This Skill

Invoke this skill when you need to:

• Understand the dual testing strategy (integration vs client)
• Set up proper test co-location
• Determine mocking strategy (hoisted vs runtime)
• Handle subpath export mocking (/client, /server)
• Validate platform separation (server-only vs client-only operations)
• Configure test execution and coverage
• Troubleshoot common test failures

For platform-specific testing:

• React Native components/screens → Use testing-setup-react-native skill
