Quick Start

# Run all tests
./testing/scripts/run_all_tests.sh

# Run specific test suites
cargo test --lib                    # Unit tests
cargo test --test '*'               # Integration tests
cargo bench                         # Benchmarks

# Generate coverage report
cargo tarpaulin --out Html

# Run security scan
cargo audit

Features

1. Automated Test Generation

  • Auto-generate unit tests from contract interfaces
  • Property-based testing with proptest
  • Fuzz testing support
  • Snapshot testing

2. Performance Testing

  • Criterion benchmarks for all operations
  • Load testing with configurable scenarios
  • Latency measurement (p50, p95, p99)
  • Gas optimization analysis

3. Security Testing

  • Vulnerability scanning (reentrancy, overflow, access control)
  • Dependency audit
  • Attack vector testing
  • Security score calculation

4. Test Data Management

  • Reusable test fixtures
  • Mock data generators
  • Test environment isolation
  • Deterministic test data

5. Analytics & Reporting

  • Code coverage tracking
  • Test execution metrics
  • Quality score calculation
  • Trend analysis

6. CI/CD Integration

  • GitHub Actions workflows
  • Automated test execution
  • Coverage reporting
  • Performance regression detection

Test Categories

Unit Tests (32 passing)

  • Insurance contract: 13 tests
  • Governance contract: 19 tests
  • Located in contracts/*/tests/

Integration Tests

  • Full flow testing
  • Cross-contract interactions
  • Located in testing/integration/

Property Tests

  • Mathematical invariants
  • Input validation
  • Located in testing/property/

Performance Tests

  • Bridge operations benchmarks
  • Escrow operations benchmarks
  • Located in benches/

Configuration

Load Testing

Edit testing/load/load_test_config.toml:

  • Concurrent users
  • Test duration
  • Operation weights
  • Performance thresholds

Coverage

Minimum coverage target: 80% Current coverage: Check testing/reports/coverage/

Security

Security score target: 90% Run: cargo audit for dependency vulnerabilities

CI/CD Pipeline

On Push/PR

  1. Code formatting check
  2. Clippy linting
  3. Unit tests
  4. Integration tests
  5. Security audit
  6. Coverage report

Nightly

  1. Full test suite
  2. Performance benchmarks
  3. Load testing
  4. Security scan

Quality Metrics

Current Status

  • Total tests: 32 passing
  • Code coverage: TBD
  • Security score: TBD
  • Performance: TBD

Targets

  • Test coverage: >80%
  • Security score: >90%
  • Bridge latency: <100ms
  • Escrow latency: <50ms

Usage Examples

Generate Tests

use testing::automated::TestGenerator;

let mut generator = TestGenerator::new("MyContract".to_string());
generator.parse_contract(Path::new("contracts/my_contract/src/lib.rs"))?;
generator.write_tests(Path::new("tests/generated"))?;

Run Benchmarks

cargo bench --bench bridge_operations
cargo bench --bench escrow_operations -- --save-baseline main

Security Scan

use testing::security::VulnerabilityScanner;

let mut scanner = VulnerabilityScanner::new();
scanner.scan_file(Path::new("contracts/teachlink/src/lib.rs"))?;
println!("{}", scanner.generate_report());

Load Testing

# Configure in testing/load/load_test_config.toml
# Run load test
cargo test --test load_test -- --ignored

Contributing

When adding new features:

  1. Write unit tests
  2. Add integration tests
  3. Update benchmarks
  4. Run security scan
  5. Check coverage
