🚀 v3.2.0 - Advanced Testing & Security Features

Major Feature Release - Enhanced testing, security, and performance!

This release introduces powerful new capabilities for enterprise Java projects, including multi-version matrix testing, TestContainers integration, container security scanning, and advanced caching strategies.

✨ New Features

🔢 Multi-Version Matrix Testing

Test your project against multiple Java versions simultaneously:

jobs:
  test:
    uses: techishthoughts-org/java-workflows/.github/workflows/java-ci.yml@v3.2
    with:
      java-version-matrix: '11,17,21,25'  # Test all LTS in parallel!
      fail-fast: false  # Continue even if one version fails

Benefits:

✅ Test all LTS versions (11, 17, 21, 25) in parallel
✅ Catch version-specific issues early
✅ Configurable fail-fast behavior
✅ Independent OS and Java version matrices

🐳 TestContainers Integration

Real database and service testing with automatic container management:

steps:
  - uses: techishthoughts-org/java-workflows/.github/actions/testcontainers-test@v3.2
    with:
      build-tool: 'maven'
      java-version: '21'
      test-profile: 'integration-test'
      containers: 'postgres,redis,kafka'  # Auto-preload containers
      parallel-tests: true

Supported Containers:

📦 Databases: PostgreSQL, MySQL, MariaDB, MongoDB
📦 Caching: Redis
📦 Messaging: Kafka, RabbitMQ
📦 Search: Elasticsearch

Benefits:

✅ No mocking required - test against real services
✅ Automatic container lifecycle management
✅ Preloading for faster test execution
✅ Consistent test environment across all runs
✅ Automatic cleanup after tests

🔒 Container Security Scanning

Comprehensive container image security analysis:

jobs:
  scan:
    uses: techishthoughts-org/java-workflows/.github/workflows/container-scan.yml@v3.2
    with:
      image-name: 'myapp'
      image-tag: '${{ github.sha }}'
      scan-severity: 'MEDIUM'
      fail-on-severity: 'HIGH'
      generate-sbom: true

Security Tools:

🔍 Trivy - Comprehensive vulnerability scanner
🔍 Grype - Additional validation
📦 Syft - SBOM generation

Features:

✅ Multi-severity reporting (CRITICAL, HIGH, MEDIUM, LOW)
✅ SARIF upload to GitHub Security tab
✅ Container SBOM generation (CycloneDX)
✅ Configurable failure thresholds
✅ Detailed vulnerability reports

💾 Advanced Caching

Multi-layer caching for significantly faster builds:

steps:
  - uses: techishthoughts-org/java-workflows/.github/actions/advanced-cache@v3.2
    with:
      build-tool: 'maven'
      cache-dependencies: true          # Maven/Gradle dependencies
      cache-build-outputs: true         # Compiled classes
      cache-test-data: true             # Test fixtures

Performance Impact:

⚡ 40-60% faster builds overall
⚡ Dependencies: ~2-5 minutes saved
⚡ Build outputs: ~1-3 minutes saved
⚡ Test data: ~30-60 seconds saved

Caching Layers:

💾 Dependencies (Maven ~/.m2, Gradle ~/.gradle)
💾 Build outputs (target/classes, build/classes)
💾 Test data and fixtures
💾 Intelligent fallback keys
💾 Platform-specific optimization
