Many teams adopt Playwright after years of investment in other UI frameworks. A deliberate migration plan helps you move tests gradually without losing coverage or overwhelming the team.
Planning a Migration from Legacy UI Suites
Start by identifying high-value flows and the most brittle tests in your legacy suite. Migrate these first to get quick wins in stability and feedback time.
Typical migration phases:
1. Inventory existing suites (Selenium, Cypress, others)
2. Choose priority flows (checkout, login, onboarding)
3. Rebuild those flows in Playwright with modern patterns
4. Run both suites in parallel for a period
5. Decommission legacy tests as confidence growsGood communication with stakeholders is key: explain what is being migrated, what will change in reporting and how teams should adapt their workflows.
Common Mistakes
Mistake 1 — Copying legacy tests line by line
This preserves old problems.
❌ Wrong: Recreating brittle patterns like hard waits or fragile selectors.
✅ Correct: Adopt Playwright’s strengths, such as locators, fixtures and auto-waiting.
Mistake 2 — Migrating low-value tests first
This delays benefits.
❌ Wrong: Spending months rewriting obscure edge-case tests.
✅ Correct: Focus on critical paths where better tooling yields the most impact.
