Flutter Test Runner

Purpose

This skill helps run and manage Sanmill's Flutter test suite, ensuring code quality and functional correctness.

Use Cases

• Run unit and widget tests
• Run integration tests with real AI engine
• Generate and view test coverage reports
• Verify functionality after code modifications
• Validate changes in CI/CD pipelines

Test Structure Overview

src/ui/flutter_app/
├── test/                # Unit and widget tests (Dart VM, fast)
├── integration_test/    # Integration tests (real platform + AI engine)
└── test_driver/         # Test drivers

Quick Commands

Unit and Widget Tests

cd src/ui/flutter_app

# Run all tests
flutter test

# Run specific test file
flutter test test/game/position_test.dart

# Run with coverage
flutter test --coverage

Integration Tests

# From repository root - use the project script (recommended)
./run-integration-test.sh --full           # Complete test suite
./run-integration-test.sh --single         # Single test case
./run-integration-test.sh --help           # Show options

# Manual execution (from src/ui/flutter_app)
flutter test integration_test/ -d linux    # Linux
flutter test integration_test/ -d macos    # macOS
flutter test integration_test/ -d windows  # Windows

Test Types Comparison

Key difference : Integration tests use the real C++ AI engine and must run on actual platforms, not the Dart VM.

Coverage Reports

# Generate coverage
flutter test --coverage

# View summary (requires lcov)
lcov --summary coverage/lcov.info

# Generate HTML report
genhtml coverage/lcov.info -o coverage/html
# Then open coverage/html/index.html

Coverage targets : Overall ≥80%, Critical logic ≥90%, UI ≥70%

Common Issues & Solutions

1. MissingPluginException

• Symptom : Tests fail with plugin errors
• Cause : Running integration tests with flutter test test/
• Fix : Use flutter test integration_test/ -d <platform>

2. Import Errors

• Fix : Run flutter pub get or flutter clean && flutter pub get

3. Integration Test Failures (AI-related)

• Cause : AI behavior may vary between runs
• Solution :
  1. Check if AI moves are reasonable
  2. Update expected sequences in test data if needed
  3. Ensure consistent AI configuration

4. Timeout Issues

• Increase test timeout in test configuration
• Check async operation handling
• Adjust maxWaitTimeMs for AI tests

Best Practices

1. Run unit tests frequently - Fast feedback loop
2. Run integration tests before commits - Catch platform-specific issues
3. Check coverage for new code - Maintain quality standards
4. Keep tests independent - Tests should not depend on each other
5. Update expectations carefully - For AI tests, verify moves are actually correct

Reference Documentation

• Integration tests : src/ui/flutter_app/integration_test/AUTOMATED_MOVE_TESTS_README.md
• Flutter testing guide : https://docs.flutter.dev/testing
• Test directories : src/ui/flutter_app/test/ and src/ui/flutter_app/integration_test/

Output Format

Test results should report:

• ✓ Pass/fail status with counts
• ✗ Failure details with stack traces
• 📊 Coverage percentage (if generated)
• ⏱ Execution time
• 💡 Actionable recommendations
