### Game Logic
- **Board**: 20x8 grid of cards using standard playing card assets
- **Matrix System**: 10x22 matrix with border padding (8x20 actual game board)
- **Matching Rules**: Cards must be identical and connected via valid paths:
- **I-pattern**: Straight line (horizontal or vertical)
- **L-pattern**: Single 90-degree turn
- **U-pattern**: Path extending to board border with two turns
- **Z-pattern**: Two-turn path through empty cells
- **Game Features**: New game, hint system, card selection with visual feedback
- **Game Features**: New game, hint system, card selection with visual feedback, debug visualization toggle
- **Testing**: Comprehensive Jest test suite with 90+ test cases covering all patterns

# Pikachu Game Testing System
A comprehensive Jest-based testing framework for the Pikachu card matching game logic, validating all four connection patterns with professional testing capabilities.
## Overview
This testing system validates all four Pikachu game patterns:
- **I-pattern**: Direct line connections (horizontal/vertical)
- **L-pattern**: Single-turn connections (90-degree turns)
- **U-pattern**: Border extension connections (extending beyond board edges)
- **Z-pattern**: Two-turn connections through intermediate points
## Project Structure
```

```
## Installation
```bash
# Install dependencies
npm install
# Jest is already included in devDependencies
```
## Usage
### Run All Tests
```bash
# Run all tests
npm test
# Run tests with coverage
npm run test:coverage
# Run tests in watch mode
npm run test:watch
# Run tests with detailed output
npm run test:verbose
# Run tests silently (minimal output)
npm run test:silent
```
### Run Specific Pattern Tests
```bash
# Test individual patterns
npm run test:i # I-pattern tests
npm run test:l # L-pattern tests
npm run test:u # U-pattern tests
npm run test:z # Z-pattern tests
```
### Run Individual Test Files
```bash
# Run specific test files
jest test/patterns/i-pattern.test.js
jest test/patterns/l-pattern.test.js
jest test/patterns/u-pattern.test.js
jest test/patterns/z-pattern.test.js
jest test/all-patterns.test.js
```
## Test Structure
### Base Test Class (`PikachuBaseTest`)
The base class provides common utilities for all pattern tests:
```javascript
import { PikachuBaseTest } from '../base/PikachuBaseTest.js';
describe('My Pattern Tests', () => {
let tester;
beforeEach(() => {
tester = new PikachuBaseTest();
});
test('should connect cards with specific pattern', () => {
// Create empty board
const matrix = tester.createEmptyMatrix();
// Place cards
tester.placeCard(matrix, 1, 1, 1); // row, col, cardType
tester.placeCard(matrix, 1, 5, 1);
// Create and run test case
const testCase = tester.createTestCase(
'Test description',
matrix,
1, 1, 1, 5, // from (1,1) to (1,5)
true, // expected result
'I-pattern' // expected pattern
);
tester.expectTestCase(testCase);
});
});
```
### Test Case Creation
```javascript
// Create test case with all parameters
const testCase = tester.createTestCase(
name, // Test description
matrix, // Board matrix
row1, col1, // First card position
row2, col2, // Second card position
expected, // Expected validity (true/false)
expectedPattern, // Expected pattern type (optional)
expectedError // Expected error message (optional)
);
// Execute test case with Jest assertions
tester.expectTestCase(testCase);
```
### Board Coordinates
- **Matrix**: 10x22 (height x width) including border padding
- **Game board**: 8x20 (actual playable area)
- **Coordinates**: 1-indexed for game board positions
- **Border**: Row 0, row 9, col 0, col 21 are always empty (type 0)
### Card Types
- **0**: Empty cell (passable)
- **1, 2, 3, ...**: Different card types
- **Same type**: Required for valid connections
## Jest Features
### Custom Matchers
The system includes custom Jest matchers for game-specific assertions:
```javascript
// Test if a move is valid
expect(result).toBeValidMove();
// Test if a move uses specific pattern
expect(result).toHavePattern('I-pattern');
// Standard Jest assertions also work
expect(result.valid).toBe(true);
expect(result.error).toContain('expected error message');
```
### Test Organization
Tests are organized using Jest's `describe` blocks:
```javascript
describe('I-Pattern Tests', () => {
describe('Horizontal Lines', () => {
test('should connect cards with clear horizontal path', () => {
// Test implementation
});
});
describe('Vertical Lines', () => {
test('should connect cards with clear vertical path', () => {
// Test implementation
});
});
});
```
## Example Test Cases
### I-Pattern Test
```javascript
test('should connect cards with clear horizontal path', () => {
const matrix = tester.createEmptyMatrix();
tester.placeCard(matrix, 1, 1, 1);
tester.placeCard(matrix, 1, 5, 1);
const testCase = tester.createTestCase(
'Horizontal line - clear path',
matrix,
1, 1, 1, 5,
true,
'I-pattern'
);
tester.expectTestCase(testCase);
});
```
### L-Pattern Test
```javascript
test('should connect cards with L-shape via corner', () => {
const matrix = tester.createEmptyMatrix();

```
## Adding New Tests
1. **Add test to existing pattern file**:
```javascript
test('should handle new scenario', () => {
const matrix = tester.createEmptyMatrix();
// Set up test scenario
const testCase = tester.createTestCase(/* parameters */);
tester.expectTestCase(testCase);
});
```
2. **Create new test file**:
```javascript
import { PikachuBaseTest } from '../base/PikachuBaseTest.js';
describe('New Pattern Tests', () => {
let tester;
beforeEach(() => {
tester = new PikachuBaseTest();
});
// Add tests here
});
```
## Configuration
### Jest Configuration (`jest.config.js`)
```javascript
export default {
testEnvironment: 'node',
testMatch: ['**/test/**/*.test.js'],
collectCoverageFrom: ['src/game/logic/**/*.js'],
coverageThreshold: {
global: {
branches: 80,
functions: 80,
lines: 80,
statements: 80
}
}
};
```
### Package.json Scripts
```json
{
"scripts": {
"test": "jest",
"test:watch": "jest --watch",
"test:coverage": "jest --coverage",
"test:i": "jest test/patterns/i-pattern.test.js",
"test:l": "jest test/patterns/l-pattern.test.js",
"test:u": "jest test/patterns/u-pattern.test.js",
"test:z": "jest test/patterns/z-pattern.test.js"
}
}
```
## Debugging
### Debug Individual Tests
```bash
# Run specific test with verbose output
jest test/patterns/i-pattern.test.js --verbose
# Run single test case
jest test/patterns/i-pattern.test.js -t "should connect cards with clear horizontal path"
# Run tests with debugging
node --inspect-brk node_modules/.bin/jest test/patterns/i-pattern.test.js --runInBand
```
### Print Board State
```javascript
test('debug board state', () => {
const matrix = tester.createEmptyMatrix();
tester.placeCard(matrix, 1, 1, 1);
tester.placeCard(matrix, 1, 5, 1);
tester.printBoard(matrix); // Prints board to console
// Continue with test
});
```
### Manual Testing
```javascript
test('manual game logic testing', () => {
const matrix = tester.createEmptyMatrix();
tester.placeCard(matrix, 1, 1, 1);
tester.placeCard(matrix, 1, 5, 1);
tester.game.loadBoardFromMatrix(matrix);
const result = tester.game.testMove(1, 1, 1, 5);
console.log('Test result:', result);
expect(result.valid).toBe(true);
});
```
## Coverage Goals
The test suite aims for high coverage:
- **Branches**: 80%+ (all conditional paths)
- **Functions**: 80%+ (all methods tested)
- **Lines**: 80%+ (all code lines executed)
- **Statements**: 80%+ (all statements covered)
## Performance
### Test Execution Time
- **Individual patterns**: ~0.5-1.0 seconds
- **All patterns**: ~2-3 seconds
- **With coverage**: ~3-5 seconds
### Optimization Tips
- Use `beforeEach` for common setup
- Avoid complex board setups in simple tests
- Use `test.only()` for focused development
- Use `test.skip()` for temporary test disabling
## Continuous Integration
The test suite is designed to work with CI/CD systems:
```bash
# CI command
npm test -- --coverage --watchAll=false
# Exit code 0 = success, 1 = failure
echo $?
```
## Contributing
1. Write tests for new patterns or edge cases
2. Follow existing test structure and naming
3. Ensure all tests pass before submitting
4. Add documentation for new test utilities
5. Maintain high code coverage
## Troubleshooting
### Common Issues
1. **Import errors**: Ensure `"type": "module"` in package.json
2. **Test timeouts**: Check for infinite loops in game logic
3. **Memory issues**: Clear test data in `beforeEach`
4. **Pattern conflicts**: Verify pattern priority logic
### Debug Commands
```bash
# Check Jest configuration
jest --showConfig
# Run tests with maximum verbosity
jest --verbose --detectOpenHandles
# Clear Jest cache
jest --clearCache
# Run tests without cache
jest --no-cache
```
