# GitLab 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)
#   BROWSER_CACHE_PATH - browser cache path (frontend/fullstack only; omit for backend)

stages:
  - lint
  - test
  - burn-in
  - report
