## Running Tests

### Using Cargo
```bash
# Run all tests
cargo test

# Run specific test file
cargo test interactive_unit_tests

# Run with verbose output
cargo test -- --test-threads=1 --nocapture

# Run performance tests
cargo test interactive_performance_tests

# Run integration tests
cargo test interactive_integration_tests
```

### Using Test Script
```bash
# Run comprehensive test suite
./test_interactive.sh

# Run with custom timeout
./test_interactive.sh
```

### Manual Testing
```bash
# Build jbuild
cargo build --bin jbuild

# Test interactive commands
cargo run --bin jbuild -- interactive --help
cargo run --bin jbuild -- monitor --help
cargo run --bin jbuild -- profile --help

# Test with a real project
cargo run --bin jbuild -- interactive --dashboard
cargo run --bin jbuild -- monitor --duration 10
cargo run --bin jbuild -- profile --format json
```

## Test Artifacts

### Generated Files
- **Profile Reports**: JSON, Markdown, and Text reports
- **Test Projects**: Temporary Maven and Gradle projects
- **Output Logs**: Command execution logs and error messages
- **Performance Metrics**: Execution times and throughput data

### Cleanup
- All temporary directories are automatically cleaned up
- Test artifacts are removed after test completion
- Environment variables are properly managed

## Test Validation

5. **Environment**: Ensure proper Java and tool setup

### Debug Commands
```bash
# Check binary exists
ls -la target/debug/jbuild

# Check dependencies
cargo tree

# Check build
cargo check --bin jbuild

# Run single test
cargo test test_name -- --nocapture
```

## Continuous Integration
