Healthcare SaaS Platform — Regression Overhaul
US HealthTech · 100K+ Active UsersBusiness Challenge
Release cycles blocked by 4-hour manual regression. Engineering team unable to ship more than once per week. Customer-facing bugs eroding trust.
Root Cause
Legacy architecture without isolation patterns. Implicit waits everywhere. Shared test state. No parallel execution capability.
Technical Problem
Monolithic Selenium suite with 60% flaky tests. No CI/CD integration. Test data coupling causing cascading failures. Zero API-level coverage.
Solution Strategy
Built Playwright + TypeScript POM framework from scratch with custom fixtures, API mocking, visual regression, and GitHub Actions CI/CD pipeline with parallel sharding.
Metrics
Business Impact
$200K+ annual cost savings. Daily releases enabled. Customer-facing bugs reduced by 70%. Engineering velocity doubled.
Lessons Learned
Invest in API-level testing pyramid first. Parallel sharding is non-negotiable for scale. Flaky test elimination requires locator strategy overhaul, not retries.
