keep lightweight operations truly lightweight +- **Validate output format**: Docker "table" format always shows header - need to check for data rows +- **Handle edge cases**: Empty output, no containers, stopped containers all need proper handling + +### Specific Problems to Avoid in Future +- **Don't add polling when state is already validated** - check the execution flow first +- **Don't assume containers need time to start in lightweight mode** - global setup already handles this +- **Always test actual execution time** - especially for parallel tests where delays compound +- **Keep lightweight mode truly lightweight** - < 1 second, not up to 30 seconds +- **Detect header-only output** - check line count to distinguish header from actual data +- **Provide diagnostic fallbacks** - show stopped containers when no running containers found + +### Reference for Future WIs +**When adding diagnostics to test infrastructure**: +1. **Understand the execution context** - is this called before or after containers are ready? +2. **Distinguish between setup and validation** - global setup waits, lightweight mode doesn't need to +3. **Keep it fast** - if it's called per test in parallel, keep it under 1 second +4. **Don't poll unnecessarily** - only poll when state is uncertain, not when already validated +5. **Test parallel execution** - measure actual time with multiple tests running in parallel +6. **Validate output format** - check for both header and data, not just non-empty output +7. **Handle edge cases** - no containers, stopped containers, runtime failures +8. **Provide actionable diagnostics** - show both running and stopped containers for debugging + +**Critical Lessons**: +1. **Original requirement was visibility, not validation** - just display, don't wait +2. **Docker table format always shows header** - must check line count to detect actual data +3. **Empty output ≠ no output** - header-only is technically not empty but has no useful data +4. **Multiple iterations may be needed** - performance issue, then output detection issue +5. **Test with real scenarios** - both with and without containers to validate all cases
