+# Pake CLI Test Suite
+
+This directory contains the complete test suite for the Pake CLI tool.
+
+## Quick Start
+
+```bash
+# Run all tests (unit + integration + builder)
+npm test
+```
+
+## Test Structure
+
+```tree
+tests/
+├── index.js              # Main test runner
+├── cli.test.js           # Unit tests for CLI functionality
+├── integration.test.js   # Integration tests
+├── builder.test.js       # Platform-specific builder tests
+├── test.config.js        # Shared test configuration
+└── README.md            # This file
+```
+
+## Test Categories
+
+### 1. Unit Tests (`cli.test.js`)
+
+Fast tests that verify individual CLI functions:
+
+- ✅ Version command
+- ✅ Help command
+- ✅ Argument validation
+- ✅ URL validation (including weekly.tw93.fun)
+- ✅ Number validation
+- ✅ Dependency checks
+- ✅ Response time
+- ✅ Remote icon URL validation
+- ✅ Configuration merging logic
+
+### 2. Integration Tests (`integration.test.js`)
+
+Tests that verify components work together:
+
+- ✅ Process spawning
+- ✅ Interactive mode
+- ✅ Build command construction
+- ✅ File system permissions
+- ✅ Dependency resolution
+
+### 3. Builder Tests (`builder.test.js`)
+
+Platform-specific builder logic tests:
+
+- ✅ Mac file naming patterns
+- ✅ Windows file naming patterns
+- ✅ Linux file naming patterns (deb/rpm/AppImage)
+- ✅ Architecture detection logic
+- ✅ Multi-arch build detection
+- ✅ Target format validation
+
+All tests run automatically with: `npm test`
+
+## Test Commands
+
+| Command             | Description             | Coverage                     | Duration    |
+| ------------------- | ----------------------- | ---------------------------- | ----------- |
+| `npm test`          | Run all automated tests | Unit + Integration + Builder | ~30 seconds |
+| `npm run cli:build` | Build CLI for testing   | Development setup            | ~5 seconds  |
+
+**GitHub Actions Integration:**
+
+- Automated testing on push/PR to main/dev branches
+- Multi-platform testing (Ubuntu, Windows, macOS)
+- Quality checks and code formatting validation
+
+## Manual Testing Scenarios
+
+### Basic Usage
+
+```bash
+# Test basic app creation with weekly.tw93.fun
+node dist/cli.js https://weekly.tw93.fun --name "Weekly"
+
+# Test with custom dimensions
+node dist/cli.js https://weekly.tw93.fun --name "Weekly" --width 1200 --height 800
+
+# Test debug mode
+node dist/cli.js https://weekly.tw93.fun --name "DebugApp" --debug
+```
+
+### Advanced Features
+
+```bash
+# Test with remote CDN icon
+node dist/cli.js https://weekly.tw93.fun --name "IconWeekly" --icon "https://gw.alipayobjects.com/os/k/fw/weekly.icns"
+
+# Test with injection files (create test files first)
+echo "body { background: red; }" > test.css
+echo "console.log('injected');" > test.js
+node dist/cli.js https://weekly.tw93.fun --name "InjectionApp" --inject ./test.css,./test.js
+
+# Test fullscreen app
+node dist/cli.js https://weekly.tw93.fun --name "FullWeekly" --fullscreen
+
+# Test system tray integration
+node dist/cli.js https://weekly.tw93.fun --name "TrayWeekly" --show-system-tray
+```
+
+### Platform-Specific (macOS)
+
+```bash
+# Test universal binary
+node dist/cli.js https://weekly.tw93.fun --name "Weekly" --multi-arch
+
+# Test hidden title bar
+node dist/cli.js https://weekly.tw93.fun --name "ImmersiveWeekly" --hide-title-bar
+
+# Test dark mode
+node dist/cli.js https://weekly.tw93.fun --name "DarkWeekly" --dark-mode
+```
+
+## Test Configuration
+
+Tests use configuration from `test.config.js`:
+
+```javascript
+export const TIMEOUTS = {
+  QUICK: 3000, // Quick commands
+  MEDIUM: 10000, // Validation tests
+  LONG: 300000, // Build tests
+};
+
+export const TEST_URLS = {
+  WEEKLY: "https://weekly.tw93.fun",
+  VALID: "https://example.com",
+  GITHUB: "https://github.com",
+  INVALID: "not://a/valid[url]",
+};
+
+export const TEST_ASSETS = {
+  WEEKLY_ICNS: "https://gw.alipayobjects.com/os/k/fw/weekly.icns",
+};
+```
+
+## Adding New Tests
+
+### Unit Test
+
+```javascript
+// In cli.test.js
+runner.addTest(
+  "My New Test",
+  () => {
+    // Test logic here
+    return true; // or false
+  },
+  "Test description"
+);
+```
+
+### Integration Test
+
+```javascript
+// In integration.test.js
+runner.addTest(
+  "My Integration Test",
+  async () => {
+    // Async test logic
+    return await someAsyncOperation();
+  },
+  TIMEOUTS.MEDIUM
+);
+```
+
+## Continuous Integration
+
+The project uses simplified GitHub Actions workflows:
+
+### Current Workflows:
+
+- **`quality-and-test.yml`** - Runs all tests, code formatting, and Rust quality checks
+- **`claude-unified.yml`** - Claude AI integration for code review and assistance
+- **`release.yml`** - Handles releases, app building, and Docker publishing
+- **`pake-cli.yaml`** - Manual CLI building workflow
+- **`pake_build_single_app.yaml`** - Reusable single app building workflow
+
+### Integration Example:
+
+```yaml
+# Automatic testing on push/PR
+- name: Run Quality & Tests
+  run: npm test
+
+# Manual CLI building
+- name: Build CLI
+  run: npm run cli:build
+```
+
+## Troubleshooting
+
+### Common Issues
+
+1. **"CLI file not found"**
+
+   ```bash
+   npm run cli:build
+   ```
+
+2. **"Permission denied"**
+
+   ```bash
+   chmod +x tests/index.js
+   ```
+
+3. **"Timeout errors"**
+   - Increase timeout in `test.config.js`
+   - Check system resources
+
+### Debug Mode
+
+Run tests with debug output:
+
+```bash
+DEBUG=1 npm test
+```
+
+## Performance Expectations
+
+| Platform  | First Build | Subsequent | Memory |
+| --------- | ----------- | ---------- | ------ |
+| M1 Mac    | 2-3 min     | 30-45s     | ~200MB |
+| Intel Mac | 3-4 min     | 45-60s     | ~250MB |
+| Linux     | 4-5 min     | 60-90s     | ~300MB |
+| Windows   | 5-6 min     | 90-120s    | ~350MB |
+
+## Contributing
+
+When adding new features:
+
+1. Add unit tests for new functions
+2. Add integration tests for new workflows
+3. Update manual test scenarios
+4. Run full test suite before submitting
+
+```bash
+# Pre-commit test routine
+npm run cli:build
+npm test
