// Jenkinsfile CI/CD Pipeline for Test Execution
// Generated by BMad TEA Agent - Test Architect Module
// Optimized for: Parallel Sharding, Burn-In Loop
// Stack: {test_stack_type} | Framework: {test_framework}
//
// Variables to customize per project:
//   INSTALL_CMD       - dependency install command (e.g., npm ci, pnpm install --frozen-lockfile)
//   TEST_CMD          - main test command (e.g., npm run test:e2e, npm test, npx vitest)
//   LINT_CMD          - lint command (e.g., npm run lint)
//   BROWSER_INSTALL   - browser install command (frontend/fullstack only; omit for backend)
//
// Node.js version management — choose one:
//   Option A (recommended): Configure NodeJS Plugin in Jenkins Global Tool Configuration,
//     then add to pipeline:  tools { nodejs 'NodeJS-24' }
//   Option B: Use nvm (pre-installed on agent) — this template uses nvm as the default
//   Option C: Use a Docker agent — agent { docker { image 'node:24' } }
