Code Review: This is a well-crafted solution that replaces the symlink with a wrapper script. The implementation correctly uses exec with proper argument handling, follows Ruby conventions with frozen_string_literal pragma, and has appropriate file permissions. The hardcoded route=/ makes sense for the dummy app since it routes to pages#index which displays all test components. No security concerns identified. Minor suggestion: consider adding a comment explaining why / is the appropriate route. Recommendation: APPROVE

Code Review

Overall Assessment

The change from a symlink to a wrapper script is a good solution for providing custom default arguments to the dummy app. This approach maintains flexibility while ensuring the dummy app uses the correct route.

Code Quality & Best Practices

Positive Aspects:

• Clean and simple implementation
• Properly uses exec to replace the process (no zombie processes)
• Preserves all command-line arguments with *ARGV
• Maintains executable permissions
• Uses proper shebang and frozen string literal pragma

Suggestions for Improvement:

1. Path Construction: Consider using File.expand_path for more robust path resolution
2. Error Handling: Add a check to ensure the target script exists before executing

Potential Issues

• No critical bugs identified
• The relative path traversal is fragile but acceptable for a test dummy app

Performance Considerations

• Using exec is efficient - it replaces the current process rather than spawning a child
• No performance concerns

Security Concerns

• No security issues identified
• The script does not process untrusted input or perform dangerous operations

Test Coverage

Missing Tests: The PR should include tests to verify:

1. The wrapper script correctly passes the --route=/ argument
2. Additional arguments are properly forwarded
3. The script handles the base script not existing gracefully

Additional Notes

• The removal of the symlink in favor of a wrapper script is a good architectural decision
• This change aligns well with the existing DEFAULT_ROUTE mechanism in the base script
• Consider documenting this pattern if other dummy apps might need similar customization

Recommendation

Approved with suggestions - The implementation is solid and achieves its goal. The suggested improvements would make the script more robust but are not blocking issues.
