Plan for improving logging and output in tstest

!! FIRST: Reread /home/philkunz/.claude/CLAUDE.md to ensure following all guidelines !!

Goal - ✅ MOSTLY COMPLETED

• ✅ Make test output cleaner and more visually appealing
• ✅ Add structured logging capabilities
• ✅ Support different verbosity levels
• ✅ Improve CI/CD compatibility
• ✅ Add progress indicators and timing summaries

Current State - UPDATED

• ✅ Clean, modern visual design with Unicode characters
• ✅ Structured output format (JSON support)
• ✅ Multiple verbosity levels (quiet, normal, verbose)
• ✅ Real-time output with cleaner formatting
• ✅ Better error aggregation and display
• ✅ TAP protocol support integrated with new logger

Completed Improvements

1. ✅ Created new TsTestLogger class

• ✅ Centralized logging with consistent formatting
• ✅ Support for different output modes (normal, quiet, verbose)
• ✅ Better visual hierarchy with modern Unicode characters
• ✅ Progress indicators for multiple test files
• ✅ Structured error collection and display

2. ✅ Updated visual design

• ✅ Replaced heavy separators with cleaner alternatives
• ✅ Used better emoji and Unicode characters
• ✅ Added indentation for hierarchical display
• ✅ Grouped related information visually
• ✅ Added color coding consistently

3. ✅ Added command-line options

• ✅ --quiet for minimal CI-friendly output
• ✅ --verbose for detailed debugging information
• ✅ --no-color for environments without color support
• ✅ --json for structured JSON output
• ⏳ --log-file <path> for persistent logging (TODO)

4. ✅ Improved progress feedback

• ⏳ Show progress bar for multiple files (TODO)
• ✅ Display current file being executed
• ✅ Show real-time test counts
• ⏳ Add ETA for long test suites (TODO)

5. ✅ Better error and summary display

• ✅ Collect all errors and display at end
• ✅ Show timing metrics and performance summary (in verbose mode)
• ✅ Highlight slowest tests (in verbose mode)
• ✅ Add test failure context

6. ✅ Browser console integration

• ✅ Clearly separate browser logs from test output
• ⏳ Add browser log filtering options (TODO)
• ✅ Format browser errors specially

Implementation Steps - COMPLETED

Phase 1: ✅ Core Logger Implementation

1. ✅ Created tstest.logging.ts with TsTestLogger class
2. ✅ Added LogOptions interface for configuration
3. ✅ Implemented basic formatting methods
4. ✅ Added progress and summary methods

Phase 2: ✅ Integration

1. ✅ Updated CLI to accept new command-line options
2. ✅ Modified TsTest class to use new logger
3. ✅ Updated TapParser to use structured logging
4. ✅ Updated TapCombinator for better summaries

Phase 3: ✅ Visual Improvements

1. ✅ Replaced all existing separators
2. ✅ Updated color scheme
3. ✅ Added emoji and Unicode characters
4. ✅ Implemented hierarchical output

Phase 4: ✅ Advanced Features

1. ✅ Add JSON output format
2. ⏳ Implement file-based logging (TODO)
3. ✅ Add performance metrics collection
4. ✅ Create error aggregation system

Phase 5: ✅ Browser Integration

1. ✅ Update browser console forwarding
2. ✅ Add browser log formatting
3. ✅ Implement browser-specific indicators

Files modified

• ✅ ts/tstest.logging.ts - New logger implementation (created)
• ✅ ts/index.ts - Added CLI options parsing
• ✅ ts/tstest.classes.tstest.ts - Integrated new logger
• ✅ ts/tstest.classes.tap.parser.ts - Updated output formatting
• ✅ ts/tstest.classes.tap.combinator.ts - Improved summary display
• ❌ ts/tstest.logprefixes.ts - Still in use, can be deprecated later
• ❌ package.json - No new dependencies needed

Success Criteria - ACHIEVED

• ✅ Cleaner, more readable test output
• ✅ Configurable verbosity levels
• ✅ Better CI/CD integration
• ✅ Improved error visibility
• ✅ Performance metrics available
• ✅ Consistent visual design
• ✅ Maintained backward compatibility

Summary of Implementation

The logging improvement plan has been successfully implemented with the following achievements:

1. Created a new centralized TsTestLogger class that handles all output formatting
2. Added multiple output modes: quiet, normal, verbose, and JSON
3. Improved visual design with modern Unicode characters and emojis
4. Added CLI argument parsing for all new options
5. Integrated the logger throughout the codebase (TsTest, TapParser, TapCombinator)
6. Better error aggregation and display with failed tests shown at the end
7. Performance metrics available in verbose mode
8. Clean, hierarchical output that's much more readable

Remaining TODOs

Only a few minor features remain unimplemented:

• File-based logging (--log-file option)
• Progress bar visualization
• ETA for long test suites
• Browser log filtering options

The core logging improvements are complete and provide a much better user experience!
