Halodoc automated web performance testing by integrating Lighthouse into their CI/CD pipeline to catch regressions before deployment. They built a custom framework around Lighthouse's Node.js library that runs parallel tests against critical URLs, validates Core Web Vitals against thresholds, and blocks merge requests that exceed performance limits. The solution includes an orchestrator for coordination, worker processes for isolated audits, a retry manager for stability, and a result aggregator that computes median values across multiple runs. This shift-left approach replaced reactive production monitoring with proactive pre-merge validation, reducing manual testing and preventing performance issues from reaching users.
