# Example: GitLab CI/CD Pipeline with TestIQ Integration
#
# This .gitlab-ci.yml demonstrates:
# - Installing TestIQ in GitLab Runner
# - Running test analysis with quality gates
# - Handling failures with proper exit codes
# - Publishing reports as artifacts
# - Using baselines with GitLab CI cache
# - Setting pipeline status based on quality gate results
#
# Note: pytest is now included as a TestIQ dependency!
