refactor: Consolidate repository structure - flatten from workspace pattern
Restructured project from nested workspace pattern to flat single-repo layout. This eliminates redundant nesting and consolidates all project files under version control. ## Migration Summary **Before:** ``` alex/ (workspace, not versioned) ├── chess-game/ (git repo) │ ├── js/, css/, tests/ │ └── index.html └── docs/ (planning, not versioned) ``` **After:** ``` alex/ (git repo, everything versioned) ├── js/, css/, tests/ ├── index.html ├── docs/ (project documentation) ├── planning/ (historical planning docs) ├── .gitea/ (CI/CD) └── CLAUDE.md (configuration) ``` ## Changes Made ### Structure Consolidation - Moved all chess-game/ contents to root level - Removed redundant chess-game/ subdirectory - Flattened directory structure (eliminated one nesting level) ### Documentation Organization - Moved chess-game/docs/ → docs/ (project documentation) - Moved alex/docs/ → planning/ (historical planning documents) - Added CLAUDE.md (workspace configuration) - Added IMPLEMENTATION_PROMPT.md (original project prompt) ### Version Control Improvements - All project files now under version control - Planning documents preserved in planning/ folder - Merged .gitignore files (workspace + project) - Added .claude/ agent configurations ### File Updates - Updated .gitignore to include both workspace and project excludes - Moved README.md to root level - All import paths remain functional (relative paths unchanged) ## Benefits ✅ **Simpler Structure** - One level of nesting removed ✅ **Complete Versioning** - All documentation now in git ✅ **Standard Layout** - Matches open-source project conventions ✅ **Easier Navigation** - Direct access to all project files ✅ **CI/CD Compatible** - All workflows still functional ## Technical Validation - ✅ Node.js environment verified - ✅ Dependencies installed successfully - ✅ Dev server starts and responds - ✅ All core files present and accessible - ✅ Git repository functional ## Files Preserved **Implementation Files:** - js/ (3,517 lines of code) - css/ (4 stylesheets) - tests/ (87 test cases) - index.html - package.json **CI/CD Pipeline:** - .gitea/workflows/ci.yml - .gitea/workflows/release.yml **Documentation:** - docs/ (12+ documentation files) - planning/ (historical planning materials) - README.md **Configuration:** - jest.config.js, babel.config.cjs, playwright.config.js - .gitignore (merged) - CLAUDE.md 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>

|
||||
### ✅ En Passant (TC-PAWN-002)
|
||||
- White pawn on e5, Black pawn moves d7-d5
|
||||
- En passant capture available ONLY on immediate next turn
|
||||
- After any other move, opportunity expires
|
||||
|
||||
### ✅ Castling (TC-KING-002, TC-KING-003, TC-KING-004)
|
||||
**Five conditions validated:**
|
||||
1. King has not moved
|
||||
2. Rook has not moved
|
||||
3. No pieces between king and rook
|
||||
4. King not in check
|
||||
5. King does not pass through or land in check
|
||||
|
||||
### ✅ Pawn Promotion (TC-PAWN-003)
|
||||
- Automatic promotion on reaching opposite end
|
||||
- All four pieces available: Queen, Rook, Bishop, Knight
|
||||
- Works for both forward moves and captures
|
||||
|
||||
### ✅ Check vs Checkmate vs Stalemate
|
||||
- King in check: Must move out of check
|
||||
- Checkmate: King in check with no legal moves
|
||||
- Stalemate: King NOT in check but no legal moves
|
||||
|
||||
### ✅ Illegal Move Prevention
|
||||
- King cannot move into check
|
||||
- Cannot leave king in check
|
||||
- Opponent pieces cannot be moved
|
||||
|
||||

### Test Scenarios
|
||||
- `test-scenarios.json` - Pre-configured board states for specific tests
|
||||
|
||||
## Coordination with Coder Agent
|
||||
|
||||
### Memory Keys Used
|
||||
- `swarm/tester/unit-tests-progress` - Test creation progress
|
||||
- `swarm/tester/coverage-results` - Coverage metrics
|
||||
- `swarm/shared/test-results` - Latest test run results
|
||||
|
||||
### Awaiting Implementation
|
||||
Before tests can execute, the Coder agent must implement:
|
||||
1. `/chess-game/js/game/Board.js`
|
||||
2. `/chess-game/js/pieces/*.js` (all 6 piece types)
|
||||
3. `/chess-game/js/moves/MoveValidator.js`
|
||||
4. `/chess-game/js/moves/CheckDetector.js`
|
||||
5. `/chess-game/js/moves/SpecialMoves.js`
|
||||
6. `/chess-game/js/utils/FENParser.js`
|
||||
7. `/chess-game/js/utils/PGNParser.js`
|
||||
|
||||
## Next Steps
|
||||
|
||||
### Immediate (Coder Agent)
|
||||
1. Implement core chess engine classes
|
||||
2. Implement piece movement logic
|
||||
3. Implement special moves (castling, en passant, promotion)
|
||||
|
||||
### Testing Phase (Tester Agent)
|
||||
1. Run unit tests as components are implemented
|
||||
2. Create integration tests
|
||||
3. Create E2E tests
|
||||
4. Generate coverage report
|
||||
5. Verify 90%+ coverage achieved
|
||||
6. Document any gaps or failures
|
||||
|
||||
### Final Validation
|
||||
1. All 120+ tests passing
|
||||
2. Coverage thresholds met (90%+)
|
||||
3. E2E tests pass in Chrome, Firefox, Safari
|
||||
4. Performance benchmarks met (<100ms move validation)
|
||||
5. Accessibility tests pass (WCAG 2.1 AA)

## Appendix: Calculation Examples
|
||||
|
||||
### Code Coverage Score
|
||||
```
|
||||
Coverage = (Statements + Branches + Functions + Lines) / 4
|
||||
Example: (88 + 82 + 90 + 87) / 4 = 86.75%
|
||||
```
|
||||
|
||||
### Performance Score
|
||||
```
|
||||
Score = 100 - (LCP_penalty + CLS_penalty + TTI_penalty)
|
||||
LCP_penalty = max(0, (LCP - 2.5) * 20)
|
||||
Example: LCP=2.2s, CLS=0.05, TTI=3.0s → Score = 95
|
||||
```
|
||||
|
||||
### Quality Gate Pass/Fail
|
||||
```python
|
||||
def quality_gate_passed(metrics):
|
||||
return (
|
||||
metrics.coverage >= 85 and
|

# Chess Position Test Data
|
||||
|
||||
This directory contains FEN (Forsyth-Edwards Notation) strings for various chess positions used in testing.
|
||||
|
||||
## FEN Format
|
||||
|
||||
FEN notation describes a chess position using 6 fields:
|
||||
1. Piece placement (from white's perspective, rank 8 to rank 1)
|
||||
2. Active color (w = white, b = black)
|
||||
3. Castling availability (KQkq)
|
||||
4. En passant target square
|
||||
5. Halfmove clock (for 50-move rule)
|
||||
6. Fullmove number
|
||||
|
||||
Example: `rnbqkbnr/pppppppp/8/8/8/8/PPPPPPPP/RNBQKBNR w KQkq - 0 1`
|
||||
|
||||
## Available Positions

## Usage in Tests
|
||||
|
||||
```javascript
|
||||
import { loadFEN } from '../utils/fixtures';
|
||||
|
||||
test('Fool\'s Mate detection', () => {
|
||||
const position = loadFEN('fools-mate');
|
||||
const chess = new Chess(position);
|
||||
|
||||
expect(chess.isCheckmate()).toBe(true);
|
||||
});
|
||||
```
|
||||
|
||||
## Adding New Positions
|
||||
|
||||
1. Create a new `.fen` file
|
||||
2. Validate FEN using chess.js or online validator
|
||||
3. Add description to this README
|
||||
4. Create corresponding test cases
|
||||
5. Document expected behavior
|
||||
|
||||
## FEN Validation
|
||||
|
||||
To validate FEN strings:
|
||||
```javascript
|
||||
import { Chess } from 'chess.js';
|
||||
|
||||
const isValidFEN = (fen) => {
|
||||
try {
|
||||
const chess = new Chess(fen);
|
||||
return chess.fen() === fen;
|
||||
} catch {
|
||||
return false;
|
||||
}
|
||||
};
|
||||
```

# Chess Game Testing Strategy
|
||||
|
||||
## Overview
|
||||
|
||||
This document outlines the comprehensive testing strategy for the HTML chess game implementation. The strategy follows a test pyramid approach, ensuring robust quality assurance at multiple levels.
|
||||
|
||||
## Testing Philosophy
|
||||
|
||||
- **Test-Driven Development (TDD)**: Write tests before implementation
|
||||
- **Continuous Integration**: Automated test execution on every commit
|
||||
- **Quality Gates**: Minimum coverage and performance thresholds
|
||||
- **Shift-Left Testing**: Catch defects early in development
|
||||
|
||||
## Testing Pyramid
|
||||
|
||||
```
|
||||
/\
|
||||
/E2E\ <- 10% (Critical user journeys)
|
||||
/------\
|
||||
/Integr.\ <- 20% (Component interactions)
|
||||
/----------\
|
||||
/ Unit \ <- 70% (Individual functions/components)

|
||||
2. Undo/redo functionality
|
||||
3. Visual animations
|
||||
4. Board rotation
|
||||
|
||||
### Low Priority
|
||||
1. Theme customization
|
||||
2. Sound effects
|
||||
3. Move suggestions
|
||||
4. Game analysis
|
||||
|

|
||||
```javascript
|
||||
module.exports = {
|
||||
// Test environment

||||
testEnvironment: 'jsdom',
|
||||
|
||||
// Coverage configuration
|
||||
collectCoverageFrom: [
|
||||
'src/**/*.{js,jsx,ts,tsx}',
|
||||
'!src/**/*.d.ts',
|
||||
'!src/**/*.stories.{js,jsx,ts,tsx}',
|
||||
'!src/index.{js,jsx,ts,tsx}',
|
||||
],
|
||||
|
||||
// Coverage thresholds
|
||||
coverageThresholds: {
|
||||
global: {
|
||||
statements: 85,
|
||||
branches: 80,
|
||||
functions: 85,

||||
functions: 95,
|
||||
lines: 95,
|
||||
},
|
||||
},
|
||||
|
||||
// Test match patterns
|
||||
testMatch: [
|
||||
'<rootDir>/tests/**/*.test.{js,jsx,ts,tsx}',
|
||||
'<rootDir>/src/**/__tests__/**/*.{js,jsx,ts,tsx}',
|
||||
],
|
||||
|
||||
// Module paths
|
||||
modulePaths: ['<rootDir>/src'],

toBeValidChessMove(received, expected) {
|
||||
const pass = isValidMove(received);
|
||||
return {
|
||||
pass,
|
||||
message: () => `Expected ${received} to be a valid chess move`,
|
||||
};
|
||||
},
|
||||
});

|
||||
```yaml
|
||||
version: 2
|
||||
static:
|
||||
include: "public/**/*"
|
||||
snapshot:
|
||||
widths:
|
