✅ CI Pipeline Enhancements Checklist

🧪 Testing & Quality

• Unit Testing
  Run unit tests to verify component behavior.
  📌 Result: Step passes or fails based on test results.

  Measure test coverage using JaCoCo.
  📌 Result: Generates coverage report, optionally uploaded to SonarQube.

• Test Coverage Thresholds
  Enforce minimum test coverage percentage.
  📌 Result: Fail pipeline if coverage is too low.

• Integration Testing
  Validate system-level interactions using DB/services.
  📌 Result: Pass/fail with logs or reports.

• Mutation Testing
  Use PIT to test effectiveness of unit tests.
  📌 Result: Generate mutation coverage score report.

---

📦 Build & Artifacts

• Build Artifacts
  Generate .jar or .war files using Maven/Gradle.
  📌 Result: Artifact available in target/ or build/ directory.

• Upload Artifact
  Save the build artifact for deployment or sharing.
  📌 Result: Upload to CI/CD storage or artifact repository.

---

🧰 Code Quality & Security

• Static Code Analysis
  Use SonarQube to detect code smells, bugs, and vulnerabilities.
  📌 Result: Dashboard report, optional step failure.

• Linting/Code Style Checks
  Enforce consistent code style via Checkstyle, PMD, etc.
  📌 Result: Step fails if style violations exist.

• Dependency Vulnerability Scanning
  Scan for CVEs in dependencies using OWASP or Snyk.
  📌 Result: Vulnerability report, fail on critical issues.

• License Compliance Check
  Verify that dependencies use approved licenses.
  📌 Result: Report generated or step failure on violations.

---

🐳 Docker & Deployment Prep

• Docker Image Build
  Create a Docker image for deployment.
  📌 Result: Image built and tagged locally.

• Docker Image Push
  Push Docker image to a container registry.
  📌 Result: Image available in DockerHub, ECR, etc.

• Database Migration Check
  Validate DB migrations using Flyway or Liquibase.
  📌 Result: DB schema updated or step fails.

---

🧠 Automation & Intelligence

• Pull Request Comments
  Add test/coverage results as comments in PRs.
  📌 Result: Auto-comment on PRs with CI summary.

• Git Tagging/Versioning
  Automatically tag releases (e.g., v1.0.0).
  📌 Result: Git tag created and pushed.

• Environment Matrix Testing
  Test against multiple JDK versions or OS environments.
  📌 Result: Matrix jobs with parallel results.

• Caching Dependencies
  Cache Maven/Gradle dependencies to speed up builds.
  📌 Result: Faster pipeline runs.

• Notifications (Slack/Email/etc.)
  Alert team of pipeline results.
  📌 Result: Notification sent on success/failure.

• Secret Scanning
  Detect committed secrets in codebase.
  📌 Result: Alert or block PR if secrets are found.

Notes:

• Feel free to break each task into separate issues or PRs.
• Update this checklist as you make progress.
