Motivation

After completing the System.CommandLine 2.0.0-beta5 migration, comprehensive testing and validation is required to ensure:

• All CLI functionality works correctly with the new API
• No regressions have been introduced
• Performance improvements are realized
• Error handling and validation scenarios work properly
• Help system displays correctly

Task Description

Conduct comprehensive testing and validation of the System.CommandLine upgrade to ensure all functionality works correctly and no regressions have been introduced.

Testing Areas:

1. Functional Testing:

• Test all CLI commands with various parameter combinations
• Verify help output for all commands (--help)
• Test error scenarios and validation messages
• Verify subcommand functionality (DataDictionaryCommandHandler)
• Test option parsing with required/optional parameters

2. Integration Testing:

• Test complete workflows end-to-end
• Verify dependency injection continues to work
• Test file I/O operations through CLI
• Verify logging and error output

3. Performance Validation:

• Measure application startup time improvements
• Verify parsing performance improvements
• Test memory usage (should be reduced)

4. Regression Testing:

• Verify all existing command-line scenarios work
• Test edge cases and error conditions
• Verify output format consistency
• Test with various input combinations

Commands to Test:

• init-project with various options
• extract-model with different configurations
• data-dictionary subcommands
• enrich-model functionality
• export-model with different formats
• query-model operations
• show-object display

Acceptance Criteria

• All CLI commands execute successfully with test parameters
• Help system displays correctly for all commands
• Error handling works properly for invalid inputs
• Subcommands function correctly
• No performance regressions observed
• All existing CLI scenarios pass testing
• Memory usage is reduced as expected
• Startup time improvements are measurable
• Integration with IHost dependency injection works
• Logging and error output function correctly

Impact / Risk

• Dependencies: Requires completion of issues [Chore]: Update System.CommandLine package reference to 2.0.0-beta5 #15, [Chore]: Migrate Program.cs to System.CommandLine 2.0.0-beta5 API #16, [Chore]: Update CommandHandler base class for System.CommandLine 2.0.0-beta5 #17, and [Chore]: Migrate all command handlers to System.CommandLine 2.0.0-beta5 API #18
• Risk Level: Medium - Final validation step before completion
• Testing Scope: Complete CLI functionality
• Performance: Should validate expected improvements
